Replace the eay DES code with key scheule setup code by me and DES
s-box and p permutation from Richard Outerbridge implemtation (in public domain). The DES modes are implemented by me. ui.c code are from appl/login. The implementation is about 3 times slower then Eric for encryption, and about the same speed for key setup. git-svn-id: svn://svn.h5l.se/heimdal/trunk/heimdal@14585 ec53bebd-3082-4978-b11e-865c3cabbd6b

The hunt for getting a DES with plain BSD license w/o advertisement clause
|
||||
==========================================================================
|
||||
|
||||
$Id$
|
||||
|
||||
This all feels very silly given that DES is about 30 years old and now
|
||||
is deprecated.
|
||||
|
||||
Helpful documents on the way:
|
||||
|
||||
Schider's crypto wasn't that useful since it only told how to do DES,
|
||||
not how to do des fast or how to not use DES. I find this to be a
|
||||
common thread in the book, it explain each tool in great detail, but
|
||||
not its limitations.
|
||||
|
||||
Dag Arne Osvik: Efficient Implementation of the Data Encryption Standard
|
||||
|
||||
Some threads on sci.crypto was also useful.

PC1 transformations
|
||||
===================
|
||||
|
||||
|
||||
Getting the PC1 bit mangling working was hard, I never got it to work.
|
||||
|
||||
Printning out the bit usage made me realize a lookup table could be
|
||||
used since only 12 bits are used from the first half and 16 from the
|
||||
second.
|
||||
|
||||
01110000 01110000 01110000 01110000 01111000 01111000 01111000 01111000

|
||||
|
||||
The pattern is getting more obvious if its printed out where the bits
|
||||
are coming from.

Only 3 bits-table is needed for the first half and 4 bits for the
|
||||
second half because they are on diffrent shift offsets.
|
||||
|
||||
So to get the bitpattern bit-pattern
|
||||
|
||||
gen_pattern("pc1_c_3", 7, [ 5, 13, 21 ], 0, 0x1000000);
|
||||
gen_pattern("pc1_c_4", 15, [ 1, 9, 17, 25 ], 0, 0x1000000);
|
||||
gen_pattern("pc1_d_3", 7, [ 49, 41, 33 ], 32, 0x1000000);
|
||||
gen_pattern("pc1_d_4", 15, [ 57, 53, 45, 37 ], 32, 0x1000000);

|
||||
PC2 transformations
|
||||
===================
|
||||
|
||||
PC2 is also a table lookup, since its a 24 bit field, I use 4 6-bit
|
||||
lookup tables. Printing the reverse of the PC2 table reveal that some
|
||||
of the bits are not used, namely (9, 18, 22, 25) from c and (7, 10,
|
||||
15, 26) from d.
|
||||
|
||||
pc2 from c

49 37 30 46 - 34 44
|
||||
|
||||
So we generate tables for that too.
|
||||
|
||||
gen_pattern("pc2_c_1", 63, [ 5, 24, 7, 16, 6, 10 ], 0, 0x800000);

gen_pattern("pc2_c_4", 63, [ 11, 13, 4, 17, 21, 8 ], 0, 0x800000);

gen_pattern("pc2_d_3", 63, [ 41, 38, 47, 33, 40, 42 ], 28, 0x800000);

gen_pattern("pc2_d_4", 63, [ 49, 37, 30, 46, 34, 44 ], 28, 0x800000);

run './des_opts' to determin the best compile time options.

The output from des_opts should be put in the makefile options and des_enc.c

For the DEC Alpha, edit des.h and change DES_LONG to 'unsigned int'

These routines should compile on MSDOS, most 32bit and 64bit version

The only problems should be #include files that are in the wrong places.
|

|

These routines can be compiled under MSDOS.
|
||||
I have successfully encrypted files using des(1) under MSDOS and then
|

decrypted the files on a SparcStation.
|
||||
I have been able to compile and test the routines with

Microsoft C v 5.1 and Turbo C v 2.0.

The code in this library is in no way optimised for the 16bit

operation of MSDOS.

When building for glibc, ignore all of the above and just unpack into

|

As a final note on performace. Certain CPUs like sparcs and Alpha often give
|
||||
a %10 speed difference depending on the link order. It is rather anoying

when one program reports 'x' DES encrypts a second and another reports

'x*0.9' the speed.

To use this library with Bones (kerberos without DES):
|
||||
1) Get my modified Bones - eBones. It can be found on
|
||||
gondwana.ecr.mu.oz.au (128.250.1.63) /pub/athena/eBones-p9.tar.Z
|
||||
and
|
||||
nic.funet.fi (128.214.6.100) /pub/unix/security/Kerberos/eBones-p9.tar.Z
|
||||
|
||||
2) Unpack this library in src/lib/des, makeing sure it is version
|
||||
3.00 or greater (libdes.tar.93-10-07.Z). This versions differences
|
||||
from the version in comp.sources.misc volume 29 patchlevel2.
|
||||
The primarily difference is that it should compile under kerberos :-).
|
||||
It can be found at.
|
||||
ftp.psy.uq.oz.au (130.102.32.1) /pub/DES/libdes.tar.93-10-07.Z
|
||||
|
||||
Now do a normal kerberos build and things should work.
|
||||

Modes of DES
|
||||
Quite a bit of the following information has been taken from
|
||||
AS 2805.5.2
|
||||
Australian Standard
|
||||
Electronic funds transfer - Requirements for interfaces,
|
||||
Part 5.2: Modes of operation for an n-bit block cipher algorithm
|
||||
Appendix A
|
||||
|
||||
There are several different modes in which DES can be used, they are
|
||||
as follows.
|
||||
|
||||
Electronic Codebook Mode (ECB) (des_ecb_encrypt())
|
||||
- 64 bits are enciphered at a time.
|
||||
- The order of the blocks can be rearranged without detection.
|
||||
- The same plaintext block always produces the same ciphertext block
|
||||
(for the same key) making it vulnerable to a 'dictionary attack'.
|
||||
- An error will only affect one ciphertext block.
|
||||
|
||||
Cipher Block Chaining Mode (CBC) (des_cbc_encrypt())
|
||||
- a multiple of 64 bits are enciphered at a time.
|
||||
- The CBC mode produces the same ciphertext whenever the same
|
||||
plaintext is encrypted using the same key and starting variable.
|
||||
- The chaining operation makes the ciphertext blocks dependent on the
|
||||
current and all preceding plaintext blocks and therefore blocks can not
|
||||
be rearranged.
|
||||
- The use of different starting variables prevents the same plaintext
|
||||
enciphering to the same ciphertext.
|
||||
- An error will affect the current and the following ciphertext blocks.
|
||||
|
||||
Cipher Feedback Mode (CFB) (des_cfb_encrypt())
|
||||
- a number of bits (j) <= 64 are enciphered at a time.
|
||||
- The CFB mode produces the same ciphertext whenever the same
|
||||
plaintext is encrypted using the same key and starting variable.
|
||||
- The chaining operation makes the ciphertext variables dependent on the
|
||||
current and all preceding variables and therefore j-bit variables are
|
||||
chained together and con not be rearranged.
|
||||
- The use of different starting variables prevents the same plaintext
|
||||
enciphering to the same ciphertext.
|
||||
- The strength of the CFB mode depends on the size of k (maximal if
|
||||
j == k). In my implementation this is always the case.
|
||||
- Selection of a small value for j will require more cycles through
|
||||
the encipherment algorithm per unit of plaintext and thus cause
|
||||
greater processing overheads.
|
||||
- Only multiples of j bits can be enciphered.
|
||||
- An error will affect the current and the following ciphertext variables.
|
||||
|
||||
Output Feedback Mode (OFB) (des_ofb_encrypt())
|
||||
- a number of bits (j) <= 64 are enciphered at a time.
|
||||
- The OFB mode produces the same ciphertext whenever the same
|
||||
plaintext enciphered using the same key and starting variable. More
|
||||
over, in the OFB mode the same key stream is produced when the same
|
||||
key and start variable are used. Consequently, for security reasons
|
||||
a specific start variable should be used only once for a given key.
|
||||
- The absence of chaining makes the OFB more vulnerable to specific attacks.
|
||||
- The use of different start variables values prevents the same
|
||||
plaintext enciphering to the same ciphertext, by producing different
|
||||
key streams.
|
||||
- Selection of a small value for j will require more cycles through
|
||||
the encipherment algorithm per unit of plaintext and thus cause
|
||||
greater processing overheads.
|
||||
- Only multiples of j bits can be enciphered.
|
||||
- OFB mode of operation does not extend ciphertext errors in the
|
||||
resultant plaintext output. Every bit error in the ciphertext causes
|
||||
only one bit to be in error in the deciphered plaintext.
|
||||
- OFB mode is not self-synchronising. If the two operation of
|
||||
encipherment and decipherment get out of synchronism, the system needs
|
||||
to be re-initialised.
|
||||
- Each re-initialisation should use a value of the start variable
|
||||
different from the start variable values used before with the same
|
||||
key. The reason for this is that an identical bit stream would be
|
||||
produced each time from the same parameters. This would be
|
||||
susceptible to a 'known plaintext' attack.
|
||||
|
||||
Triple ECB Mode (des_3ecb_encrypt())
|
||||
- Encrypt with key1, decrypt with key2 and encrypt with key1 again.
|
||||
- As for ECB encryption but increases the effective key length to 112 bits.
|
||||
- If both keys are the same it is equivalent to encrypting once with
|
||||
just one key.
|
||||
|
||||
Triple CBC Mode (des_3cbc_encrypt())
|
||||
- Encrypt with key1, decrypt with key2 and encrypt with key1 again.
|
||||
- As for CBC encryption but increases the effective key length to 112 bits.
|
||||
- If both keys are the same it is equivalent to encrypting once with
|
||||
just one key.

The primary ftp site for this library is

|

libdes is now also shipped with SSLeay. Primary ftp site of
|
||||
ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/SSLeay-x.x.x.tar.gz
|
||||
|
||||
The best way to build this library is to build it as part of SSLeay.
|
||||
|
||||
This kit builds a DES encryption library and a DES encryption program.
|
||||
It supports ecb, cbc, ofb, cfb, triple ecb, triple cbc, triple ofb,
|
||||
triple cfb, desx, and MIT's pcbc encryption modes and also has a fast
|
||||
implementation of crypt(3).
|
||||
It contains support routines to read keys from a terminal,
|
||||
generate a random key, generate a key from an arbitrary length string,
|
||||
read/write encrypted data from/to a file descriptor.
|
||||
|
||||
The implementation was written so as to conform with the manual entry
|
||||
for the des_crypt(3) library routines from MIT's project Athena.
|
||||
|
||||
destest should be run after compilation to test the des routines.
|
||||
rpw should be run after compilation to test the read password routines.
|
||||
The des program is a replacement for the sun des command. I believe it
|
||||
conforms to the sun version.
|
||||
|
||||
The Imakefile is setup for use in the kerberos distribution.
|
||||
|
||||
These routines are best compiled with gcc or any other good
|
||||
optimising compiler.
|
||||
Just turn you optimiser up to the highest settings and run destest
|
||||
after the build to make sure everything works.
|
||||
|
||||
I believe these routines are close to the fastest and most portable DES
|
||||
routines that use small lookup tables (4.5k) that are publicly available.
|
||||
The fcrypt routine is faster than ufc's fcrypt (when compiling with
|
||||
gcc2 -O2) on the sparc 2 (1410 vs 1270) but is not so good on other machines
|
||||
(on a sun3/260 168 vs 336). It is a function of CPU on chip cache size.
|
||||
[ 10-Jan-97 and a function of an incorrect speed testing program in
|
||||
ufc which gave much better test figures that reality ].
|
||||
|
||||
It is worth noting that on sparc and Alpha CPUs, performance of the DES
|
||||
library can vary by upto %10 due to the positioning of files after application
|
||||
linkage.

Version 4.01 14/01/97
|
||||
Even faster inner loop in the DES assember for x86 and a modification
|
||||
for IP/FP which is faster on x86. Both of these changes are
|
||||
from Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk>. His
|
||||
changes make the assember run %40 faster on a pentium. This is just
|
||||
a case of getting the instruction sequence 'just right'.
|
||||
All credit to 'Svend' :-)
|
||||
Quite a few special x86 'make' targets.
|
||||
A libdes-l (lite) distribution.
|
||||
|
||||
Version 4.00
|
||||
After a bit of a pause, I'll up the major version number since this
|
||||
is mostly a performace release. I've added x86 assember and
|
||||
added more options for performance. A %28 speedup for gcc
|
||||
on a pentium and the assember is a %50 speedup.
|
||||
MIPS CPU's, sparc and Alpha are the main CPU's with speedups.
|
||||
Run des_opts to work out which options should be used.
|
||||
DES_RISC1/DES_RISC2 use alternative inner loops which use
|
||||
more registers but should give speedups on any CPU that does
|
||||
dual issue (pentium). DES_UNROLL unrolls the inner loop,
|
||||
which costs in code size.
|
||||
|
||||
Version 3.26
|
||||
I've finally removed one of the shifts in D_ENCRYPT. This
|
||||
meant I've changed the des_SPtrans table (spr.h), the set_key()
|
||||
function and some things in des_enc.c. This has definitly
|
||||
made things faster :-). I've known about this one for some
|
||||
time but I've been too lazy to follow it up :-).
|
||||
Noticed that in the D_ENCRYPT() macro, we can just do L^=(..)^(..)^..
|
||||
instead of L^=((..)|(..)|(..).. This should save a register at
|
||||
least.
|
||||
Assember for x86. The file to replace is des_enc.c, which is replaced
|
||||
by one of the assember files found in asm. Look at des/asm/readme
|
||||
for more info.
|
||||
|
||||
/* Modification to fcrypt so it can be compiled to support
|
||||
HPUX 10.x's long password format, define -DLONGCRYPT to use this.
|
||||
Thanks to Jens Kupferschmidt <bt1cu@hpboot.rz.uni-leipzig.de>. */
|
||||
|
||||
SIGWINCH case put in des_read_passwd() so the function does not
|
||||
'exit' if this function is recieved.
|
||||
|
||||
Version 3.25 17/07/96
|
||||
Modified read_pwd.c so that stdin can be read if not a tty.
|
||||
Thanks to Jeff Barber <jeffb@issl.atl.hp.com> for the patches.
|
||||
des_init_random_number_generator() shortened due to VMS linker
|
||||
limits.
|
||||
Added RSA's DESX cbc mode. It is a form of cbc encryption, with 2
|
||||
8 byte quantites xored before and after encryption.
|
||||
des_xcbc_encryption() - the name is funny to preserve the des_
|
||||
prefix on all functions.
|
||||
|
||||
Version 3.24 20/04/96
|
||||
The DES_PTR macro option checked and used by SSLeay configuration
|
||||
|
||||
Version 3.23 11/04/96
|
||||
Added DES_LONG. If defined to 'unsigned int' on the DEC Alpha,
|
||||
it gives a %20 speedup :-)
|
||||
Fixed the problem with des.pl under perl5. The patches were
|
||||
sent by Ed Kubaitis (ejk@uiuc.edu).
|
||||
if fcrypt.c, changed values to handle illegal salt values the way
|
||||
normal crypt() implementations do. Some programs apparently use
|
||||
them :-(. The patch was sent by Bjorn Gronvall <bg@sics.se>
|
||||
|
||||
Version 3.22 29/11/95
|
||||
Bug in des(1), an error with the uuencoding stuff when the
|
||||
'data' is small, thanks to Geoff Keating <keagchon@mehta.anu.edu.au>
|
||||
for the patch.
|
||||
|
||||
Version 3.21 22/11/95
|
||||
After some emailing back and forth with
|
||||
Colin Plumb <colin@nyx10.cs.du.edu>, I've tweaked a few things
|
||||
and in a future version I will probably put in some of the
|
||||
optimisation he suggested for use with the DES_USE_PTR option.
|
||||
Extra routines from Mark Murray <mark@grondar.za> for use in
|
||||
freeBSD. They mostly involve random number generation for use
|
||||
with kerberos. They involve evil machine specific system calls
|
||||
etc so I would normally suggest pushing this stuff into the
|
||||
application and/or using RAND_seed()/RAND_bytes() if you are
|
||||
using this DES library as part of SSLeay.
|
||||
Redone the read_pw() function so that it is cleaner and
|
||||
supports termios, thanks to Sameer Parekh <sameer@c2.org>
|
||||
for the initial patches for this.
|
||||
Renamed 3ecb_encrypt() to ecb3_encrypt(). This has been
|
||||
done just to make things more consistent.
|
||||
I have also now added triple DES versions of cfb and ofb.
|
||||
|
||||
Version 3.20
|
||||
Damn, Damn, Damn, as pointed out by Mike_Spreitzer.PARC@xerox.com,
|
||||
my des_random_seed() function was only copying 4 bytes of the
|
||||
passed seed into the init structure. It is now fixed to copy 8.

||||
My own suggestion is to used something like MD5 :-)
|
||||
|
||||
Version 3.19
|
||||
While looking at my code one day, I though, why do I keep on
|
||||
calling des_encrypt(in,out,ks,enc) when every function that
|
||||
calls it has in and out the same. So I dropped the 'out'
|
||||
parameter, people should not be using this function.
|
||||
|
||||
Version 3.18 30/08/95
|
||||
Fixed a few bit with the distribution and the filenames.
|
||||
3.17 had been munged via a move to DOS and back again.
|
||||
NO CODE CHANGES
|
||||
|
||||
Version 3.17 14/07/95
|
||||
Fixed ede3 cbc which I had broken in 3.16. I have also
|
||||
removed some unneeded variables in 7-8 of the routines.
|
||||
|
||||
Version 3.16 26/06/95
|
||||
Added des_encrypt2() which does not use IP/FP, used by triple
|
||||
des routines. Tweaked things a bit elsewhere. %13 speedup on
|
||||
sparc and %6 on a R4400 for ede3 cbc mode.
|
||||
|
||||
Version 3.15 06/06/95
|
||||
Added des_ncbc_encrypt(), it is des_cbc mode except that it is
|
||||
'normal' and copies the new iv value back over the top of the
|
||||
passed parameter.
|
||||
CHANGED des_ede3_cbc_encrypt() so that it too now overwrites
|
||||
the iv. THIS WILL BREAK EXISTING CODE, but since this function
|
||||
only new, I feel I can change it, not so with des_cbc_encrypt :-(.
|
||||
I need to update the documentation.
|
||||
|
||||
Version 3.14 31/05/95
|
||||
New release upon the world, as part of my SSL implementation.
|
||||
New copyright and usage stuff. Basically free for all to use
|
||||
as long as you say it came from me :-)
|
||||
|
||||
Version 3.13 31/05/95
|
||||
A fix in speed.c, if HZ is not defined, I set it to 100.0
|
||||
which is reasonable for most unixes except SunOS 4.x.
|
||||
I now have a #ifdef sun but timing for SunOS 4.x looked very
|
||||
good :-(. At my last job where I used SunOS 4.x, it was
|
||||
defined to be 60.0 (look at the old INSTALL documentation), at
|
||||
the last release had it changed to 100.0 since I now work with
|
||||
Solaris2 and SVR4 boxes.
|
||||
Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this
|
||||
one out.
|
||||
|
||||
Version 3.12 08/05/95
|
||||
As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>,
|
||||
my D_ENCRYPT macro in crypt() had an un-necessary variable.
|
||||
It has been removed.
|
||||
|
||||
Version 3.11 03/05/95
|
||||
Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys
|
||||
and one iv. It is a standard and I needed it for my SSL code.
|
||||
It makes more sense to use this for triple DES than
|
||||
3cbc_encrypt(). I have also added (or should I say tested :-)
|
||||
cfb64_encrypt() which is cfb64 but it will encrypt a partial
|
||||
number of bytes - 3 bytes in 3 bytes out. Again this is for
|
||||
my SSL library, as a form of encryption to use with SSL
|
||||
telnet.
|
||||
|
||||
Version 3.10 22/03/95
|
||||
Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls
|
||||
to cbc3_encrypt, the 2 iv values that were being returned to
|
||||
be used in the next call were reversed :-(.
|
||||
Many thanks to Bill Wade <wade@Stoner.COM> for pointing out
|
||||
this error.
|
||||
|
||||
Version 3.09 01/02/95
|
||||
Fixed des_random_key to far more random, it was rather feeble
|
||||
with regards to picking the initial seed. The problem was
|
||||
pointed out by Olaf Kirch <okir@monad.swb.de>.
|
||||
|
||||
Version 3.08 14/12/94
|
||||
Added Makefile.PL so libdes can be built into perl5.
|
||||
Changed des_locl.h so RAND is always defined.
|
||||
|
||||
Version 3.07 05/12/94
|
||||
Added GNUmake and stuff so the library can be build with
|
||||
glibc.
|
||||
|
||||
Version 3.06 30/08/94
|
||||
Added rpc_enc.c which contains _des_crypt. This is for use in
|
||||
secure_rpc v 4.0
|
||||
Finally fixed the cfb_enc problems.
|
||||
Fixed a few parameter parsing bugs in des (-3 and -b), thanks
|
||||
to Rob McMillan <R.McMillan@its.gu.edu.au>
|
||||
|
||||
Version 3.05 21/04/94
|
||||
for unsigned long l; gcc does not produce ((l>>34) == 0)
|
||||
This causes bugs in cfb_enc.
|
||||
Thanks to Hadmut Danisch <danisch@ira.uka.de>
|
||||
|
||||
Version 3.04 20/04/94
|
||||
Added a version number to des.c and libdes.a
|
||||
|
||||
Version 3.03 12/01/94
|
||||
Fixed a bug in non zero iv in 3cbc_enc.
|
||||
|
||||
Version 3.02 29/10/93
|
||||
I now work in a place where there are 6+ architectures and 14+
|
||||
OS versions :-).
|
||||
Fixed TERMIO definition so the most sys V boxes will work :-)
|
||||
|
||||
Release upon comp.sources.misc
|
||||
Version 3.01 08/10/93
|
||||
Added des_3cbc_encrypt()
|
||||
|
||||
Version 3.00 07/10/93
|
||||
Fixed up documentation.
|
||||
quad_cksum definitely compatible with MIT's now.
|
||||
|
||||
Version 2.30 24/08/93
|
||||
Triple DES now defaults to triple cbc but can do triple ecb
|
||||
with the -b flag.
|
||||
Fixed some MSDOS uuen/uudecoding problems, thanks to
|
||||
Added prototypes.
|
||||
|
||||
Version 2.22 29/06/93
|
||||
Fixed a bug in des_is_weak_key() which stopped it working :-(
|
||||
thanks to engineering@MorningStar.Com.
|
||||
|
||||
Version 2.21 03/06/93
|
||||
des(1) with no arguments gives quite a bit of help.
|
||||
Added -c (generate ckecksum) flag to des(1).
|
||||
Added -3 (triple DES) flag to des(1).
|
||||
Added cfb and ofb routines to the library.
|
||||
|
||||
Version 2.20 11/03/93
|
||||
Added -u (uuencode) flag to des(1).
|
||||
I have been playing with byte order in quad_cksum to make it
|
||||
compatible with MIT's version. All I can say is avid this
|
||||
function if possible since MIT's output is endian dependent.
|
||||
|
||||
Version 2.12 14/10/92
|
||||
Added MSDOS specific macro in ecb_encrypt which gives a %70
|
||||
speed up when the code is compiled with turbo C.
|
||||
|
||||
Version 2.11 12/10/92
|
||||
Speedup in set_key (recoding of PC-1)
|
||||
I now do it in 47 simple operations, down from 60.
|
||||
Thanks to John Fletcher (john_fletcher@lccmail.ocf.llnl.gov)
|
||||
for motivating me to look for a faster system :-)
|
||||
The speedup is probably less that 1% but it is still 13
|
||||
instructions less :-).
|
||||
|
||||
Version 2.10 06/10/92
|
||||
The code now works on the 64bit ETA10 and CRAY without modifications or
|
||||
#defines. I believe the code should work on any machine that
|
||||
defines long, int or short to be 8 bytes long.
|
||||
Thanks to Shabbir J. Safdar (shabby@mentor.cc.purdue.edu)
|
||||
for helping me fix the code to run on 64bit machines (he had
|
||||
access to an ETA10).
|
||||
Thanks also to John Fletcher <john_fletcher@lccmail.ocf.llnl.gov>
|
||||
for testing the routines on a CRAY.
|
||||
read_password.c has been renamed to read_passwd.c
|
||||
string_to_key.c has been renamed to string2key.c
|
||||
|
||||
Version 2.00 14/09/92
|
||||
Made mods so that the library should work on 64bit CPU's.
|
||||
Removed all my uchar and ulong defs. To many different
|
||||
versions of unix define them in their header files in too many
|
||||
different combinations :-)
|
||||
IRIX - Sillicon Graphics mods (mostly in read_password.c).
|
||||
Thanks to Andrew Daviel (advax@erich.triumf.ca)
|
||||
|
||||
Version 1.99 26/08/92
|
||||
Fixed a bug or 2 in enc_read.c
|
||||
Fixed a bug in enc_write.c
|
||||
Fixed a pseudo bug in fcrypt.c (very obscure).
|
||||
|
||||
Version 1.98 31/07/92
|
||||
Support for the ETA10. This is a strange machine that defines
|
||||
longs and ints as 8 bytes and shorts as 4 bytes.
|
||||
Since I do evil things with long * that assume that they are 4
|
||||
bytes. Look in the Makefile for the option to compile for
|
||||
this machine. quad_cksum appears to have problems but I
|
||||
will don't have the time to fix it right now, and this is not
|
||||
a function that uses DES and so will not effect the main uses
|
||||
of the library.
|
||||
|
||||
Version 1.97 20/05/92 eay
|
||||
Fixed the Imakefile and made some changes to des.h to fix some
|
||||
problems when building this package with Kerberos v 4.
|
||||
|
||||
Version 1.96 18/05/92 eay
|
||||
Fixed a small bug in string_to_key() where problems could
|
||||
occur if des_check_key was set to true and the string
|
||||
generated a weak key.
|
||||
|
||||
Patch2 posted to comp.sources.misc
|
||||
Version 1.95 13/05/92 eay
|
||||
Added an alternative version of the D_ENCRYPT macro in
|
||||
ecb_encrypt and fcrypt. Depending on the compiler, one version or the
|
||||
other will be faster. This was inspired by
|
||||
Dana How <how@isl.stanford.edu>, and her pointers about doing the
|
||||
*(ulong *)((uchar *)ptr+(value&0xfc))
|
||||
vs
|
||||
ptr[value&0x3f]
|
||||
to stop the C compiler doing a <<2 to convert the long array index.
|
||||
|
||||
Version 1.94 05/05/92 eay
|
||||
Fixed an incompatibility between my string_to_key and the MIT
|
||||
version. When the key is longer than 8 chars, I was wrapping
|
||||
with a different method. To use the old version, define
|
||||
OLD_STR_TO_KEY in the makefile. Thanks to
|
||||
viktor@newsu.shearson.com (Viktor Dukhovni).
|
||||
|
||||
Version 1.93 28/04/92 eay
|
||||
Fixed the VMS mods so that echo is now turned off in
|
||||
read_password. Thanks again to brennan@coco.cchs.su.oz.AU.
|
||||
MSDOS support added. The routines can be compiled with
|
||||
Turbo C (v2.0) and MSC (v5.1). Make sure MSDOS is defined.
|
||||
|
||||
Patch1 posted to comp.sources.misc
|
||||
Version 1.92 13/04/92 eay
|
||||
Changed D_ENCRYPT so that the rotation of R occurs outside of
|
||||
the loop. This required rotating all the longs in sp.h (now
|
||||
called spr.h). Thanks to Richard Outerbridge <71755.204@CompuServe.COM>
|
||||
speed.c has been changed so it will work without SIGALRM. If
|
||||
times(3) is not present it will try to use ftime() instead.
|
||||
|
||||
Version 1.91 08/04/92 eay
|
||||
Added -E/-D options to des(1) so it can use string_to_key.
|
||||
Added SVR4 mods suggested by witr@rwwa.COM
|
||||
Added VMS mods suggested by brennan@coco.cchs.su.oz.AU. If
|
||||
anyone knows how to turn of tty echo in VMS please tell me or
|
||||
implement it yourself :-).
|
||||
Changed FILE *IN/*OUT to *DES_IN/*DES_OUT since it appears VMS
|
||||
does not like IN/OUT being used.
|
||||
|
||||
Libdes posted to comp.sources.misc
|
||||
Version 1.9 24/03/92 eay
|
||||
Now contains a fast small crypt replacement.
|
||||
Added des(1) command.
|
||||
Added des_rw_mode so people can use cbc encryption with
|
||||
enc_read and enc_write.
|
||||
|
||||
Version 1.8 15/10/91 eay
|
||||
Bug in cbc_cksum.
|
||||
Many thanks to Keith Reynolds (keithr@sco.COM) for pointing this
|
||||
one out.
|
||||
|
||||
Version 1.7 24/09/91 eay
|
||||
Fixed set_key :-)
|
||||
set_key is 4 times faster and takes less space.
|
||||
There are a few minor changes that could be made.
|
||||
|
||||
Version 1.6 19/09/1991 eay
|
||||
Finally go IP and FP finished.
|
||||
Now I need to fix set_key.
|
||||
This version is quite a bit faster that 1.51
|
||||
|
||||
Version 1.52 15/06/1991 eay
|
||||
20% speedup in ecb_encrypt by changing the E bit selection
|
||||
to use 2 32bit words. This also required modification of the
|
||||
sp table. There is still a way to speedup the IP and IP-1
|
||||
(hints from outer@sq.com) still working on this one :-(.
|
||||
|
||||
Version 1.51 07/06/1991 eay
|
||||
Faster des_encrypt by loop unrolling
|
||||
Fixed bug in quad_cksum.c (thanks to hughes@logos.ucs.indiana.edu)
|
||||
|
||||
Version 1.50 28/05/1991 eay
|
||||
Optimised the code a bit more for the sparc. I have improved the
|
||||
speed of the inner des_encrypt by speeding up the initial and
|
||||
final permutations.
|
||||
|
||||
Version 1.40 23/10/1990 eay
|
||||
Fixed des_random_key, it did not produce a random key :-(
|
||||
|
||||
Version 1.30 2/10/1990 eay
|
||||
Have made des_quad_cksum the same as MIT's, the full package
|
||||
should be compatible with MIT's
|
||||
Have tested on a DECstation 3100
|
||||
Still need to fix des_set_key (make it faster).
|
||||
Does des_cbc_encrypts at 70.5k/sec on a 3100.
|
||||
|
||||
Version 1.20 18/09/1990 eay
|
||||
Fixed byte order dependencies.
|
||||
Fixed (I hope) all the word alignment problems.
|
||||
Speedup in des_ecb_encrypt.
|
||||
|
||||
Version 1.10 11/09/1990 eay
|
||||
Added des_enc_read and des_enc_write.
|
||||
Still need to fix des_quad_cksum.
|
||||
Still need to document des_enc_read and des_enc_write.

|

.SH DESCRIPTION
|
||||
.B des
|
||||
encrypts and decrypts data using the
|
||||
Data Encryption Standard algorithm.
|
||||
One of
|
||||
.B \-e, \-E
|
||||
(for encrypt) or
|
||||
.B \-d, \-D
|
||||
(for decrypt) must be specified.
|
||||
It is also possible to use
|
||||
.B \-c
|
||||
or
|
||||
.B \-C
|
||||
in conjunction or instead of the a encrypt/decrypt option to generate
|
||||
a 16 character hexadecimal checksum, generated via the
|
||||
.I des_cbc_cksum.
|
||||
.LP
|
||||
Two standard encryption modes are supported by the
|
||||
.B des
|
||||
program, Cipher Block Chaining (the default) and Electronic Code Book
|
||||
(specified with
|
||||
.B \-b
|
||||
).
|
||||
.LP
|
||||
The key used for the DES
|
||||
algorithm is obtained by prompting the user unless the
|
||||
.B `\-k
|
||||
.I key'
|
||||
option is given.
|
||||
If the key is an argument to the
|
||||
.B des
|
||||
command, it is potentially visible to users executing
|
||||
.BR ps (1)
|
||||
or a derivative. To minimise this possibility,
|
||||
.B des
|
||||
takes care to destroy the key argument immediately upon entry.
|
||||
If your shell keeps a history file be careful to make sure it is not
|
||||
world readable.
|
||||
.LP
|
||||
Since this program attempts to maintain compatibility with SunOS's
|
||||
des(1) command, there are 2 different methods used to convert the user
|
||||
supplied key to a des key.
|
||||
Whenever and one or more of
|
||||
.B \-E, \-D, \-C
|
||||
or
|
||||
.B \-3
|
||||
options are used, the key conversion procedure will not be compatible
|
||||
with the SunOS des(1) version but will use all the user supplied
|
||||
character to generate the des key.
|
||||
.B des
|
||||
command reads from standard input unless
|
||||
.I input-file
|
||||
is specified and writes to standard output unless
|
||||
.I output-file
|
||||
is given.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \-b
|
||||
Select ECB
|
||||
(eight bytes at a time) encryption mode.
|
||||
.TP
|
||||
.B \-3
|
||||
Encrypt using triple encryption.
|
||||
By default triple cbc encryption is used but if the
|
||||
.B \-b
|
||||
option is used then triple ecb encryption is performed.
|
||||
If the key is less than 8 characters long, the flag has no effect.
|
||||
.TP
|
||||
.B \-e
|
||||
Encrypt data using an 8 byte key in a manner compatible with SunOS
|
||||
des(1).
|
||||
.TP
|
||||
.B \-E
|
||||
Encrypt data using a key of nearly unlimited length (1024 bytes).
|
||||
This will product a more secure encryption.
|
||||
.TP
|
||||
.B \-d
|
||||
Decrypt data that was encrypted with the \-e option.
|
||||
.TP
|
||||
.B \-D
|
||||
Decrypt data that was encrypted with the \-E option.
|
||||
.TP
|
||||
.B \-c
|
||||
Generate a 16 character hexadecimal cbc checksum and output this to
|
||||
stderr.
|
||||
If a filename was specified after the
|
||||
.B \-c
|
||||
option, the checksum is output to that file.
|
||||
The checksum is generated using a key generated in a SunOS compatible
|
||||
manner.
|
||||
.TP
|
||||
.B \-C
|
||||
A cbc checksum is generated in the same manner as described for the
|
||||
.B \-c
|
||||
option but the DES key is generated in the same manner as used for the
|
||||
.B \-E
|
||||
and
|
||||
.B \-D
|
||||
options
|
||||
.TP
|
||||
.B \-f
|
||||
Does nothing - allowed for compatibility with SunOS des(1) command.
|
||||
.TP
|
||||
.B \-s
|
||||
Does nothing - allowed for compatibility with SunOS des(1) command.
|
||||
.TP
|
||||
.B "\-k \fIkey\fP"
|
||||
Use the encryption
|
||||
.I key
|
||||
specified.
|
||||
.TP
|
||||
.B "\-h"
|
||||
The
|
||||
.I key
|
||||
is assumed to be a 16 character hexadecimal number.
|
||||
If the
|
||||
.B "\-3"
|
||||
option is used the key is assumed to be a 32 character hexadecimal
|
||||
number.
|
||||
.TP
|
||||
.B \-u
|
||||
This flag is used to read and write uuencoded files. If decrypting,
|
||||
the input file is assumed to contain uuencoded, DES encrypted data.
|
||||
If encrypting, the characters following the -u are used as the name of
|
||||
the uuencoded file to embed in the begin line of the uuencoded
|
||||
output. If there is no name specified after the -u, the name text.des
|
||||
will be embedded in the header.

|
||||
.SH BUGS
|
||||
.LP
|
||||
The problem with using the
|
||||
.B -e
|
||||
option is the short key length.
|
||||
It would be better to use a real 56-bit key rather than an
|
||||
ASCII-based 56-bit pattern. Knowing that the key was derived from ASCII
|
||||
radically reduces the time necessary for a brute-force cryptographic attack.
|
||||
My attempt to remove this problem is to add an alternative text-key to
|
||||
DES-key function. This alternative function (accessed via
|
||||
.B -E, -D, -S
|
||||
and
|
||||
.B -3
|
||||
)
|
||||
uses DES to help generate the key.
|
||||
.LP
|
||||
Be carefully when using the -u option. Doing des -ud <filename> will
|
||||
not decrypt filename (the -u option will gobble the d option).
|
||||
.LP
|
||||
The VMS operating system operates in a world where files are always a
|
||||
multiple of 512 bytes. This causes problems when encrypted data is
|
||||
send from unix to VMS since a 88 byte file will suddenly be padded
|
||||
with 424 null bytes. To get around this problem, use the -u option
|
||||
to uuencode the data before it is send to the VMS system.

The DES library.
|
||||
|
||||
Please note that this library was originally written to operate with
|
||||
eBones, a version of Kerberos that had had encryption removed when it left
|
||||
the USA and then put back in. As such there are some routines that I will
|
||||
advise not using but they are still in the library for historical reasons.
|
||||
For all calls that have an 'input' and 'output' variables, they can be the
|
||||
same.
|
||||
|
||||
This library requires the inclusion of 'des.h'.
|
||||
|
||||
All of the encryption functions take what is called a des_key_schedule as an
|
||||
argument. A des_key_schedule is an expanded form of the des key.
|
||||
A des_key is 8 bytes of odd parity, the type used to hold the key is a
|
||||
des_cblock. A des_cblock is an array of 8 bytes, often in this library
|
||||
description I will refer to input bytes when the function specifies
|
||||
des_cblock's as input or output, this just means that the variable should
|
||||
be a multiple of 8 bytes.
|
||||
|
||||
The define DES_ENCRYPT is passed to specify encryption, DES_DECRYPT to
|
||||
specify decryption. The functions and global variable are as follows:
|
||||
|
||||
int des_check_key;
|
||||
DES keys are supposed to be odd parity. If this variable is set to
|
||||
a non-zero value, des_set_key() will check that the key has odd
|
||||
parity and is not one of the known weak DES keys. By default this
|
||||
variable is turned off;
|
||||
|
||||
void des_set_odd_parity(
|
||||
des_cblock *key );
|
||||
This function takes a DES key (8 bytes) and sets the parity to odd.
|
||||
|
||||
int des_is_weak_key(
|
||||
des_cblock *key );
|
||||
This function returns a non-zero value if the DES key passed is a
|
||||
weak, DES key. If it is a weak key, don't use it, try a different
|
||||
one. If you are using 'random' keys, the chances of hitting a weak
|
||||
key are 1/2^52 so it is probably not worth checking for them.
|
||||
|
||||
int des_set_key(
|
||||
des_cblock *key,
|
||||
des_key_schedule schedule);
|
||||
Des_set_key converts an 8 byte DES key into a des_key_schedule.
|
||||
A des_key_schedule is an expanded form of the key which is used to
|
||||
perform actual encryption. It can be regenerated from the DES key
|
||||
so it only needs to be kept when encryption or decryption is about
|
||||
to occur. Don't save or pass around des_key_schedule's since they
|
||||
are CPU architecture dependent, DES keys are not. If des_check_key
|
||||
is non zero, zero is returned if the key has the wrong parity or
|
||||
the key is a weak key, else 1 is returned.
|
||||
|
||||
int des_key_sched(
|
||||
des_cblock *key,
|
||||
des_key_schedule schedule);
|
||||
An alternative name for des_set_key().
|
||||
|
||||
int des_rw_mode; /* defaults to DES_PCBC_MODE */
|
||||
This flag holds either DES_CBC_MODE or DES_PCBC_MODE (default).
|
||||
This specifies the function to use in the enc_read() and enc_write()
|
||||
functions.
|
||||
|
||||
void des_encrypt(
|
||||
unsigned long *data,
|
||||
des_key_schedule ks,
|
||||
int enc);
|
||||
This is the DES encryption function that gets called by just about
|
||||
every other DES routine in the library. You should not use this
|
||||
function except to implement 'modes' of DES. I say this because the
|
||||
functions that call this routine do the conversion from 'char *' to
|
||||
long, and this needs to be done to make sure 'non-aligned' memory
|
||||
access do not occur. The characters are loaded 'little endian',
|
||||
have a look at my source code for more details on how I use this
|
||||
function.
|
||||
Data is a pointer to 2 unsigned long's and ks is the
|
||||
des_key_schedule to use. enc, is non zero specifies encryption,
|
||||
zero if decryption.
|
||||
|
||||
void des_encrypt2(
|
||||
unsigned long *data,
|
||||
des_key_schedule ks,
|
||||
int enc);
|
||||
This functions is the same as des_encrypt() except that the DES
|
||||
initial permutation (IP) and final permutation (FP) have been left
|
||||
out. As for des_encrypt(), you should not use this function.
|
||||
It is used by the routines in my library that implement triple DES.
|
||||
IP() des_encrypt2() des_encrypt2() des_encrypt2() FP() is the same
|
||||
as des_encrypt() des_encrypt() des_encrypt() except faster :-).
|
||||
|
||||
void des_ecb_encrypt(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
des_key_schedule ks,
|
||||
int enc);
|
||||
This is the basic Electronic Code Book form of DES, the most basic
|
||||
form. Input is encrypted into output using the key represented by
|
||||
ks. If enc is non zero (DES_ENCRYPT), encryption occurs, otherwise
|
||||
decryption occurs. Input is 8 bytes long and output is 8 bytes.
|
||||
(the des_cblock structure is 8 chars).
|
||||
|
||||
void des_ecb3_encrypt(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
des_key_schedule ks1,
|
||||
des_key_schedule ks2,
|
||||
des_key_schedule ks3,
|
||||
int enc);
|
||||
This is the 3 key EDE mode of ECB DES. What this means is that
|
||||
the 8 bytes of input is encrypted with ks1, decrypted with ks2 and
|
||||
then encrypted again with ks3, before being put into output;
|
||||
C=E(ks3,D(ks2,E(ks1,M))). There is a macro, des_ecb2_encrypt()
|
||||
that only takes 2 des_key_schedules that implements,
|
||||
C=E(ks1,D(ks2,E(ks1,M))) in that the final encrypt is done with ks1.
|
||||
|
||||
void des_cbc_encrypt(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
long length,
|
||||
des_key_schedule ks,
|
||||
des_cblock *ivec,
|
||||
int enc);
|
||||
This routine implements DES in Cipher Block Chaining mode.
|
||||
Input, which should be a multiple of 8 bytes is encrypted
|
||||
(or decrypted) to output which will also be a multiple of 8 bytes.
|
||||
The number of bytes is in length (and from what I've said above,
|
||||
should be a multiple of 8). If length is not a multiple of 8, I'm
|
||||
not being held responsible :-). ivec is the initialisation vector.
|
||||
This function does not modify this variable. To correctly implement
|
||||
cbc mode, you need to do one of 2 things; copy the last 8 bytes of
|
||||
cipher text for use as the next ivec in your application,
|
||||
or use des_ncbc_encrypt().
|
||||
Only this routine has this problem with updating the ivec, all
|
||||
other routines that are implementing cbc mode update ivec.
|
||||
|
||||
void des_ncbc_encrypt(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
long length,
|
||||
des_key_schedule sk,
|
||||
des_cblock *ivec,
|
||||
int enc);
|
||||
For historical reasons, des_cbc_encrypt() did not update the
|
||||
ivec with the value requires so that subsequent calls to
|
||||
des_cbc_encrypt() would 'chain'. This was needed so that the same
|
||||
'length' values would not need to be used when decrypting.
|
||||
des_ncbc_encrypt() does the right thing. It is the same as
|
||||
des_cbc_encrypt accept that ivec is updates with the correct value
|
||||
to pass in subsequent calls to des_ncbc_encrypt(). I advise using
|
||||
des_ncbc_encrypt() instead of des_cbc_encrypt();
|
||||
|
||||
void des_xcbc_encrypt(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
long length,
|
||||
des_key_schedule sk,
|
||||
des_cblock *ivec,
|
||||
des_cblock *inw,
|
||||
des_cblock *outw,
|
||||
int enc);
|
||||
This is RSA's DESX mode of DES. It uses inw and outw to
|
||||
'whiten' the encryption. inw and outw are secret (unlike the iv)
|
||||
and are as such, part of the key. So the key is sort of 24 bytes.
|
||||
This is much better than cbc des.
|
||||
|
||||
void des_3cbc_encrypt(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
long length,
|
||||
des_key_schedule sk1,
|
||||
des_key_schedule sk2,
|
||||
des_cblock *ivec1,
|
||||
des_cblock *ivec2,
|
||||
int enc);
|
||||
This function is flawed, do not use it. I have left it in the
|
||||
library because it is used in my des(1) program and will function
|
||||
correctly when used by des(1). If I removed the function, people
|
||||
could end up unable to decrypt files.
|
||||
This routine implements outer triple cbc encryption using 2 ks and
|
||||
2 ivec's. Use des_ede2_cbc_encrypt() instead.
|
||||
|
||||
void des_ede3_cbc_encrypt(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
long length,
|
||||
des_key_schedule ks1,
|
||||
des_key_schedule ks2,
|
||||
des_key_schedule ks3,
|
||||
des_cblock *ivec,
|
||||
int enc);
|
||||
This function implements inner triple CBC DES encryption with 3
|
||||
keys. What this means is that each 'DES' operation
|
||||
inside the cbc mode is really an C=E(ks3,D(ks2,E(ks1,M))).
|
||||
Again, this is cbc mode so an ivec is requires.
|
||||
This mode is used by SSL.
|
||||
There is also a des_ede2_cbc_encrypt() that only uses 2
|
||||
des_key_schedule's, the first being reused for the final
|
||||
encryption. C=E(ks1,D(ks2,E(ks1,M))). This form of triple DES
|
||||
is used by the RSAref library.
|
||||
|
||||
void des_pcbc_encrypt(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
long length,
|
||||
des_key_schedule ks,
|
||||
des_cblock *ivec,
|
||||
int enc);
|
||||
This is Propagating Cipher Block Chaining mode of DES. It is used
|
||||
by Kerberos v4. It's parameters are the same as des_ncbc_encrypt().
|
||||
|
||||
void des_cfb_encrypt(
|
||||
unsigned char *in,
|
||||
unsigned char *out,
|
||||
int numbits,
|
||||
long length,
|
||||
des_key_schedule ks,
|
||||
des_cblock *ivec,
|
||||
int enc);
|
||||
Cipher Feedback Back mode of DES. This implementation 'feeds back'
|
||||
in numbit blocks. The input (and output) is in multiples of numbits
|
||||
bits. numbits should to be a multiple of 8 bits. Length is the
|
||||
number of bytes input. If numbits is not a multiple of 8 bits,
|
||||
the extra bits in the bytes will be considered padding. So if
|
||||
numbits is 12, for each 2 input bytes, the 4 high bits of the
|
||||
second byte will be ignored. So to encode 72 bits when using
|
||||
a numbits of 12 take 12 bytes. To encode 72 bits when using
|
||||
numbits of 9 will take 16 bytes. To encode 80 bits when using
|
||||
numbits of 16 will take 10 bytes. etc, etc. This padding will
|
||||
apply to both input and output.
|
||||
|
||||
|
||||
void des_cfb64_encrypt(
|
||||
unsigned char *in,
|
||||
unsigned char *out,
|
||||
long length,
|
||||
des_key_schedule ks,
|
||||
des_cblock *ivec,
|
||||
int *num,
|
||||
int enc);
|
||||
This is one of the more useful functions in this DES library, it
|
||||
implements CFB mode of DES with 64bit feedback. Why is this
|
||||
useful you ask? Because this routine will allow you to encrypt an
|
||||
arbitrary number of bytes, no 8 byte padding. Each call to this
|
||||
routine will encrypt the input bytes to output and then update ivec
|
||||
and num. num contains 'how far' we are though ivec. If this does
|
||||
not make much sense, read more about cfb mode of DES :-).
|
||||
|
||||
void des_ede3_cfb64_encrypt(
|
||||
unsigned char *in,
|
||||
unsigned char *out,
|
||||
long length,
|
||||
des_key_schedule ks1,
|
||||
des_key_schedule ks2,
|
||||
des_key_schedule ks3,
|
||||
des_cblock *ivec,
|
||||
int *num,
|
||||
int enc);
|
||||
Same as des_cfb64_encrypt() accept that the DES operation is
|
||||
triple DES. As usual, there is a macro for
|
||||
des_ede2_cfb64_encrypt() which reuses ks1.
|
||||
|
||||
void des_ofb_encrypt(
|
||||
unsigned char *in,
|
||||
unsigned char *out,
|
||||
int numbits,
|
||||
long length,
|
||||
des_key_schedule ks,
|
||||
des_cblock *ivec);
|
||||
This is a implementation of Output Feed Back mode of DES. It is
|
||||
the same as des_cfb_encrypt() in that numbits is the size of the
|
||||
units dealt with during input and output (in bits).
|
||||
|
||||
void des_ofb64_encrypt(
|
||||
unsigned char *in,
|
||||
unsigned char *out,
|
||||
long length,
|
||||
des_key_schedule ks,
|
||||
des_cblock *ivec,
|
||||
int *num);
|
||||
The same as des_cfb64_encrypt() except that it is Output Feed Back
|
||||
mode.
|
||||
|
||||
void des_ede3_ofb64_encrypt(
|
||||
unsigned char *in,
|
||||
unsigned char *out,
|
||||
long length,
|
||||
des_key_schedule ks1,
|
||||
des_key_schedule ks2,
|
||||
des_key_schedule ks3,
|
||||
des_cblock *ivec,
|
||||
int *num);
|
||||
Same as des_ofb64_encrypt() accept that the DES operation is
|
||||
triple DES. As usual, there is a macro for
|
||||
des_ede2_ofb64_encrypt() which reuses ks1.
|
||||
|
||||
int des_read_pw_string(
|
||||
char *buf,
|
||||
int length,
|
||||
char *prompt,
|
||||
int verify);
|
||||
This routine is used to get a password from the terminal with echo
|
||||
turned off. Buf is where the string will end up and length is the
|
||||
size of buf. Prompt is a string presented to the 'user' and if
|
||||
verify is set, the key is asked for twice and unless the 2 copies
|
||||
match, an error is returned. A return code of -1 indicates a
|
||||
system error, 1 failure due to use interaction, and 0 is success.
|
||||
|
||||
unsigned long des_cbc_cksum(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
long length,
|
||||
des_key_schedule ks,
|
||||
des_cblock *ivec);
|
||||
This function produces an 8 byte checksum from input that it puts in
|
||||
output and returns the last 4 bytes as a long. The checksum is
|
||||
generated via cbc mode of DES in which only the last 8 byes are
|
||||
kept. I would recommend not using this function but instead using
|
||||
the EVP_Digest routines, or at least using MD5 or SHA. This
|
||||
function is used by Kerberos v4 so that is why it stays in the
|
||||
library.
|
||||
|
||||
char *des_fcrypt(
|
||||
const char *buf,
|
||||
const char *salt
|
||||
char *ret);
|
||||
This is my fast version of the unix crypt(3) function. This version
|
||||
takes only a small amount of space relative to other fast
|
||||
crypt() implementations. This is different to the normal crypt
|
||||
in that the third parameter is the buffer that the return value
|
||||
is written into. It needs to be at least 14 bytes long. This
|
||||
function is thread safe, unlike the normal crypt.
|
||||
|
||||
char *crypt(
|
||||
const char *buf,
|
||||
const char *salt);
|
||||
This function calls des_fcrypt() with a static array passed as the
|
||||
third parameter. This emulates the normal non-thread safe semantics
|
||||
of crypt(3).
|
||||
|
||||
void des_string_to_key(
|
||||
char *str,
|
||||
des_cblock *key);
|
||||
This function takes str and converts it into a DES key. I would
|
||||
recommend using MD5 instead and use the first 8 bytes of output.
|
||||
When I wrote the first version of these routines back in 1990, MD5
|
||||
did not exist but I feel these routines are still sound. This
|
||||
routines is compatible with the one in MIT's libdes.
|
||||
|
||||
void des_string_to_2keys(
|
||||
char *str,
|
||||
des_cblock *key1,
|
||||
des_cblock *key2);
|
||||
This function takes str and converts it into 2 DES keys.
|
||||
I would recommend using MD5 and using the 16 bytes as the 2 keys.
|
||||
I have nothing against these 2 'string_to_key' routines, it's just
|
||||
that if you say that your encryption key is generated by using the
|
||||
16 bytes of an MD5 hash, every-one knows how you generated your
|
||||
keys.
|
||||
|
||||
int des_read_password(
|
||||
des_cblock *key,
|
||||
char *prompt,
|
||||
int verify);
|
||||
This routine combines des_read_pw_string() with des_string_to_key().
|
||||
|
||||
int des_read_2passwords(
|
||||
des_cblock *key1,
|
||||
des_cblock *key2,
|
||||
char *prompt,
|
||||
int verify);
|
||||
This routine combines des_read_pw_string() with des_string_to_2key().
|
||||
|
||||
void des_random_seed(
|
||||
des_cblock key);
|
||||
This routine sets a starting point for des_random_key().
|
||||
|
||||
void des_random_key(
|
||||
des_cblock ret);
|
||||
This function return a random key. Make sure to 'seed' the random
|
||||
number generator (with des_random_seed()) before using this function.
|
||||
I personally now use a MD5 based random number system.
|
||||
|
||||
int des_enc_read(
|
||||
int fd,
|
||||
char *buf,
|
||||
int len,
|
||||
des_key_schedule ks,
|
||||
des_cblock *iv);
|
||||
This function will write to a file descriptor the encrypted data
|
||||
from buf. This data will be preceded by a 4 byte 'byte count' and
|
||||
will be padded out to 8 bytes. The encryption is either CBC of
|
||||
PCBC depending on the value of des_rw_mode. If it is DES_PCBC_MODE,
|
||||
pcbc is used, if DES_CBC_MODE, cbc is used. The default is to use
|
||||
DES_PCBC_MODE.
|
||||
|
||||
int des_enc_write(
|
||||
int fd,
|
||||
char *buf,
|
||||
int len,
|
||||
des_key_schedule ks,
|
||||
des_cblock *iv);
|
||||
This routines read stuff written by des_enc_read() and decrypts it.
|
||||
I have used these routines quite a lot but I don't believe they are
|
||||
suitable for non-blocking io. If you are after a full
|
||||
authentication/encryption over networks, have a look at SSL instead.
|
||||
|
||||
unsigned long des_quad_cksum(
|
||||
des_cblock *input,
|
||||
des_cblock *output,
|
||||
long length,
|
||||
int out_count,
|
||||
des_cblock *seed);
|
||||
This is a function from Kerberos v4 that is not anything to do with
|
||||
DES but was needed. It is a cksum that is quicker to generate than
|
||||
des_cbc_cksum(); I personally would use MD5 routines now.

=====
|
||||
Modes of DES
|
||||
Quite a bit of the following information has been taken from
|
||||
AS 2805.5.2
|
||||
Australian Standard
|
||||
Electronic funds transfer - Requirements for interfaces,
|
||||
Part 5.2: Modes of operation for an n-bit block cipher algorithm
|
||||
Appendix A
|
||||
|
||||
There are several different modes in which DES can be used, they are
|
||||
as follows.
|
||||
|
||||
Electronic Codebook Mode (ECB) (des_ecb_encrypt())
|
||||
- 64 bits are enciphered at a time.
|
||||
- The order of the blocks can be rearranged without detection.
|
||||
- The same plaintext block always produces the same ciphertext block
|
||||
(for the same key) making it vulnerable to a 'dictionary attack'.
|
||||
- An error will only affect one ciphertext block.
|
||||
|
||||
Cipher Block Chaining Mode (CBC) (des_cbc_encrypt())
|
||||
- a multiple of 64 bits are enciphered at a time.
|
||||
- The CBC mode produces the same ciphertext whenever the same
|
||||
plaintext is encrypted using the same key and starting variable.
|
||||
- The chaining operation makes the ciphertext blocks dependent on the
|
||||
current and all preceding plaintext blocks and therefore blocks can not
|
||||
be rearranged.
|
||||
- The use of different starting variables prevents the same plaintext
|
||||
enciphering to the same ciphertext.
|
||||
- An error will affect the current and the following ciphertext blocks.
|
||||
|
||||
Cipher Feedback Mode (CFB) (des_cfb_encrypt())
|
||||
- a number of bits (j) <= 64 are enciphered at a time.
|
||||
- The CFB mode produces the same ciphertext whenever the same
|
||||
plaintext is encrypted using the same key and starting variable.
|
||||
- The chaining operation makes the ciphertext variables dependent on the
|
||||
current and all preceding variables and therefore j-bit variables are
|
||||
chained together and can not be rearranged.
|
||||
- The use of different starting variables prevents the same plaintext
|
||||
enciphering to the same ciphertext.
|
||||
- The strength of the CFB mode depends on the size of k (maximal if
|
||||
j == k). In my implementation this is always the case.
|
||||
- Selection of a small value for j will require more cycles through
|
||||
the encipherment algorithm per unit of plaintext and thus cause
|
||||
greater processing overheads.
|
||||
- Only multiples of j bits can be enciphered.
|
||||
- An error will affect the current and the following ciphertext variables.
|
||||
|
||||
Output Feedback Mode (OFB) (des_ofb_encrypt())
|
||||
- a number of bits (j) <= 64 are enciphered at a time.
|
||||
- The OFB mode produces the same ciphertext whenever the same
|
||||
plaintext enciphered using the same key and starting variable. More
|
||||
over, in the OFB mode the same key stream is produced when the same
|
||||
key and start variable are used. Consequently, for security reasons
|
||||
a specific start variable should be used only once for a given key.
|
||||
- The absence of chaining makes the OFB more vulnerable to specific attacks.
|
||||
- The use of different start variables values prevents the same
|
||||
plaintext enciphering to the same ciphertext, by producing different
|
||||
key streams.
|
||||
- Selection of a small value for j will require more cycles through
|
||||
the encipherment algorithm per unit of plaintext and thus cause
|
||||
greater processing overheads.
|
||||
- Only multiples of j bits can be enciphered.
|
||||
- OFB mode of operation does not extend ciphertext errors in the
|
||||
resultant plaintext output. Every bit error in the ciphertext causes
|
||||
only one bit to be in error in the deciphered plaintext.
|
||||
- OFB mode is not self-synchronising. If the two operation of
|
||||
encipherment and decipherment get out of synchronism, the system needs
|
||||
to be re-initialised.
|
||||
- Each re-initialisation should use a value of the start variable
|
||||
different from the start variable values used before with the same
|
||||
key. The reason for this is that an identical bit stream would be
|
||||
produced each time from the same parameters. This would be
|
||||
susceptible to a ' known plaintext' attack.
|
||||
|
||||
Triple ECB Mode (des_ecb3_encrypt())
|
||||
- Encrypt with key1, decrypt with key2 and encrypt with key3 again.
|
||||
- As for ECB encryption but increases the key length to 168 bits.
|
||||
There are theoretic attacks that can be used that make the effective
|
||||
key length 112 bits, but this attack also requires 2^56 blocks of
|
||||
memory, not very likely, even for the NSA.
|
||||
- If both keys are the same it is equivalent to encrypting once with
|
||||
just one key.
|
||||
- If the first and last key are the same, the key length is 112 bits.
|
||||
There are attacks that could reduce the key space to 55 bit's but it
|
||||
requires 2^56 blocks of memory.
|
||||
- If all 3 keys are the same, this is effectively the same as normal
|
||||
ecb mode.
|
||||
|
||||
Triple CBC Mode (des_ede3_cbc_encrypt())
|
||||
- Encrypt with key1, decrypt with key2 and then encrypt with key3.
|
||||
- As for CBC encryption but increases the key length to 168 bits with
|
||||
the same restrictions as for triple ecb mode.

.SH DESCRIPTION
|
||||
.B des
|
||||
encrypts and decrypts data using the
|
||||
Data Encryption Standard algorithm.
|
||||
One of
|
||||
.B \-e, \-E
|
||||
(for encrypt) or
|
||||
.B \-d, \-D
|
||||
(for decrypt) must be specified.
|
||||
It is also possible to use
|
||||
.B \-c
|
||||
or
|
||||
.B \-C
|
||||
in conjunction or instead of the a encrypt/decrypt option to generate
|
||||
a 16 character hexadecimal checksum, generated via the
|
||||
.I des_cbc_cksum.
|
||||
.LP
|
||||
Two standard encryption modes are supported by the
|
||||
.B des
|
||||
program, Cipher Block Chaining (the default) and Electronic Code Book
|
||||
(specified with
|
||||
.B \-b
|
||||
).
|
||||
.LP
|
||||
The key used for the DES
|
||||
algorithm is obtained by prompting the user unless the
|
||||
.B `\-k
|
||||
.I key'
|
||||
option is given.
|
||||
If the key is an argument to the
|
||||
.B des
|
||||
command, it is potentially visible to users executing
|
||||
.BR ps (1)
|
||||
or a derivative. To minimise this possibility,
|
||||
.B des
|
||||
takes care to destroy the key argument immediately upon entry.
|
||||
If your shell keeps a history file be careful to make sure it is not
|
||||
world readable.
|
||||
.LP
|
||||
Since this program attempts to maintain compatability with sunOS's
|
||||
des(1) command, there are 2 different methods used to convert the user
|
||||
supplied key to a des key.
|
||||
Whenever and one or more of
|
||||
.B \-E, \-D, \-C
|
||||
or
|
||||
.B \-3
|
||||
options are used, the key conversion procedure will not be compatible
|
||||
with the sunOS des(1) version but will use all the user supplied
|
||||
character to generate the des key.
|
||||
.B des
|
||||
command reads from standard input unless
|
||||
.I input-file
|
||||
is specified and writes to standard output unless
|
||||
.I output-file
|
||||
is given.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \-b
|
||||
Select ECB
|
||||
(eight bytes at a time) encryption mode.
|
||||
.TP
|
||||
.B \-3
|
||||
Encrypt using triple encryption.
|
||||
By default triple cbc encryption is used but if the
|
||||
.B \-b
|
||||
option is used then triple ecb encryption is performed.
|
||||
If the key is less than 8 characters long, the flag has no effect.
|
||||
.TP
|
||||
.B \-e
|
||||
Encrypt data using an 8 byte key in a manner compatible with sunOS
|
||||
des(1).
|
||||
.TP
|
||||
.B \-E
|
||||
Encrypt data using a key of nearly unlimited length (1024 bytes).
|
||||
This will product a more secure encryption.
|
||||
.TP
|
||||
.B \-d
|
||||
Decrypt data that was encrypted with the \-e option.
|
||||
.TP
|
||||
.B \-D
|
||||
Decrypt data that was encrypted with the \-E option.
|
||||
.TP
|
||||
.B \-c
|
||||
Generate a 16 character hexadecimal cbc checksum and output this to
|
||||
stderr.
|
||||
If a filename was specified after the
|
||||
.B \-c
|
||||
option, the checksum is output to that file.
|
||||
The checksum is generated using a key generated in a sunOS compatible
|
||||
manner.
|
||||
.TP
|
||||
.B \-C
|
||||
A cbc checksum is generated in the same manner as described for the
|
||||
.B \-c
|
||||
option but the DES key is generated in the same manner as used for the
|
||||
.B \-E
|
||||
and
|
||||
.B \-D
|
||||
options
|
||||
.TP
|
||||
.B \-f
|
||||
Does nothing - allowed for compatibility with sunOS des(1) command.
|
||||
.TP
|
||||
.B \-s
|
||||
Does nothing - allowed for compatibility with sunOS des(1) command.
|
||||
.TP
|
||||
.B "\-k \fIkey\fP"
|
||||
Use the encryption
|
||||
.I key
|
||||
specified.
|
||||
.TP
|
||||
.B "\-h"
|
||||
The
|
||||
.I key
|
||||
is assumed to be a 16 character hexadecimal number.
|
||||
If the
|
||||
.B "\-3"
|
||||
option is used the key is assumed to be a 32 character hexadecimal
|
||||
number.
|
||||
.TP
|
||||
.B \-u
|
||||
This flag is used to read and write uuencoded files. If decrypting,
|
||||
the input file is assumed to contain uuencoded, DES encrypted data.
|
||||
If encrypting, the characters following the -u are used as the name of
|
||||
the uuencoded file to embed in the begin line of the uuencoded
|
||||
output. If there is no name specified after the -u, the name text.des
|
||||
will be embedded in the header.

||||
.SH BUGS
|
||||
.LP
|
||||
The problem with using the
|
||||
.B -e
|
||||
option is the short key length.
|
||||
It would be better to use a real 56-bit key rather than an
|
||||
ASCII-based 56-bit pattern. Knowing that the key was derived from ASCII
|
||||
radically reduces the time necessary for a brute-force cryptographic attack.
|
||||
My attempt to remove this problem is to add an alternative text-key to
|
||||
DES-key function. This alternative function (accessed via
|
||||
.B -E, -D, -S
|
||||
and
|
||||
.B -3
|
||||
)
|
||||
uses DES to help generate the key.
|
||||
.LP
|
||||
Be carefully when using the -u option. Doing des -ud <filename> will
|
||||
not decrypt filename (the -u option will gobble the d option).
|
||||
.LP
|
||||
The VMS operating system operates in a world where files are always a
|
||||
multiple of 512 bytes. This causes problems when encrypted data is
|
||||
send from unix to VMS since a 88 byte file will suddenly be padded
|
||||
with 424 null bytes. To get around this problem, use the -u option
|
||||
to uuencode the data before it is send to the VMS system.

# 11 April 1996 - patched to circumvent Perl 5 (through 5.002) problem
|
||||
# with sign-extension on right shift operations.
|

#
|

# eay - 92/08/31 - I think I have fixed all problems for 64bit
|
||||
# versions of perl but I could be wrong since I have not tested it yet :-).
|
||||
#
|
||||
# This is an implementation of DES in perl.
|
||||
# The two routines (des_set_key and des_ecb_encrypt)
|
||||
# take 8 byte objects as arguments.
|
||||
#
|
||||
# des_set_key takes an 8 byte string as a key and returns a key schedule
|
||||
# for use in calls to des_ecb_encrypt.
|
||||
# des_ecb_encrypt takes three arguments, the first is a key schedule
|
||||
# (make sure to pass it by reference with the *), the second is 1
|
||||
# to encrypt, 0 to decrypt. The third argument is an 8 byte object
|
||||
# to encrypt. The function returns an 8 byte object that has been
|
||||
# DES encrypted.
|
||||
#
|
||||
# example:
|
||||
# require 'des.pl'
|
||||
#
|
||||
# $key =pack("C8",0x12,0x23,0x45,0x67,0x89,0xab,0xcd,0xef);
|
||||
# @ks= &des_set_key($key);
|
||||
#
|
||||
# $outbytes= &des_ecb_encrypt(*ks,1,$data);
|
||||
# @enc =unpack("C8",$outbytes);
|
||||
#

.SH DESCRIPTION
|
||||
This library supports various DES encryption related operations. It differs
|
||||
from the
|
||||
.I crypt, setkey, and encrypt
|
||||
library routines in that it provides
|
||||
a true DES encryption, without modifying the algorithm,
|
||||
and executes much faster.
|
||||
.PP
|
||||
For each key that may be simultaneously active, create a
|
||||
.B des_key_schedule
|
||||
struct,
|
||||
defined in "des.h". Next, create key schedules (from the 8-byte keys) as
|
||||
needed, via
|
||||
.I des_set_key,
|
||||
prior to using the encryption or checksum routines. Then
|
||||
setup the input and output areas. Make sure to note the restrictions
|
||||
on lengths being multiples of eight bytes. Finally, invoke the
|
||||
encryption/decryption routines,
|
||||
.I des_ecb_encrypt
|
||||
or
|
||||
.I des_cbc_encrypt
|
||||
or
|
||||
.I des_pcbc_encrypt,
|
||||
or, to generate a cryptographic checksum, use
|
||||
.I quad_cksum
|
||||
(fast) or
|
||||
.I des_cbc_cksum
|
||||
(slow).
|
||||
.PP
|
||||
A
|
||||
.I des_cblock
|
||||
struct is an 8 byte block used as the fundamental unit for DES data and
|
||||
keys, and is defined as:
|
||||
.PP
|
||||
.B typedef unsigned char des_cblock[8];
|
||||
.PP
|
||||
and a
|
||||
.I des_key_schedule,
|
||||
is defined as:
|
||||
.PP
|
||||
.B typedef struct des_ks_struct {des_cblock _;} des_key_schedule[16];
|
||||
.PP
|
||||
.I des_read_password
|
||||
writes the string specified by
|
||||
.I prompt
|
||||
to the standard
|
||||
output, turns off echo (if possible)
|
||||
and reads an input string from standard input until terminated with a newline.
|
||||
If
|
||||
.I verify
|
||||
is non-zero, it prompts and reads input again, for use
|
||||
in applications such as changing a password; both
|
||||
versions are compared, and the input is requested repeatedly until they
|
||||
match. Then
|
||||
.I des_read_password
|
||||
converts the input string into a valid DES key, internally
|
||||
using the
|
||||
.I des_string_to_key
|
||||
routine. The newly created key is copied to the
|
||||
area pointed to by the
|
||||
.I key
|
||||
argument.
|
||||
.I des_read_password
|
||||
returns a zero if no errors occurred, or a -1
|
||||
indicating that an error
|
||||
occurred trying to manipulate the terminal echo.
|
||||
.PP
|
||||
.PP
|
||||
.I des_string_to_key
|
||||
converts an arbitrary length null-terminated string
|
||||
to an 8 byte DES key, with odd byte parity, per FIPS specification.
|
||||
A one-way function is used to convert the string to a key, making it
|
||||
very difficult to reconstruct the string from the key.
|
||||
The
|
||||
.I str
|
||||
argument is a pointer to the string, and
|
||||
.I key
|
||||
should
|
||||
point to a
|
||||
.I des_cblock
|
||||
supplied by the caller to receive the generated key.
|
||||
No meaningful value is returned. Void is not used for compatibility with
|
||||
other compilers.
|
||||
.PP
|
||||
.PP
|
||||
.I des_random_key
|
||||
generates a random DES encryption key (eight bytes), set to odd parity per
|
||||
FIPS
|
||||
specifications.
|
||||
This routine uses the current time, process id, and a counter
|
||||
as a seed for the random number generator.
|
||||
The caller must supply space for the output key, pointed to
|
||||
by argument
|
||||
.I key,
|
||||
then after calling
|
||||
.I des_random_key
|
||||
should
|
||||
call the
|
||||
.I des_set_key
|
||||
routine when needed.
|
||||
No meaningful value is returned. Void is not used for compatibility
|
||||
with other compilers.
|
||||
.PP
|
||||
.PP
|
||||
.I des_set_key
|
||||
calculates a key schedule from all eight bytes of the input key, pointed
|
||||
to by the
|
||||
.I key
|
||||
argument, and outputs the schedule into the
|
||||
.I des_key_schedule
|
||||
indicated by the
|
||||
.I schedule
|
||||
argument. Make sure to pass a valid eight byte
|
||||
key; no padding is done. The key schedule may then be used in subsequent
|
||||
encryption/decryption/checksum operations. Many key schedules may be
|
||||
cached for later use. The user is responsible to clear keys and schedules
|
||||
as soon as no longer needed, to prevent their disclosure.
|
||||
The routine also checks the key
|
||||
parity, and returns a zero if the key parity is correct (odd), a -1
|
||||
indicating a key parity error, or a -2 indicating use of an illegal
|
||||
weak key. If an error is returned, the key schedule was not created.
|
||||
.PP
|
||||
.PP
|
||||
.I des_ecb_encrypt
|
||||
is the basic DES encryption routine that encrypts or decrypts a single 8-byte
|
||||
block in
|
||||
.B electronic code book
|
||||
mode. It always transforms the input data, pointed to by
|
||||
.I input,
|
||||
into the output data, pointed to by the
|
||||
.I output
|
||||
argument.
|
||||
.PP
|
||||
If the
|
||||
.I encrypt
|
||||
argument is non-zero, the
|
||||
.I input
|
||||
(cleartext) is encrypted into the
|
||||
.I output
|
||||
(ciphertext) using the key_schedule specified by the
|
||||
.I schedule
|
||||
argument, previously set via
|
||||

.I des_cbc_encrypt
|

encrypts/decrypts using the
|
||||
.B cipher-block-chaining mode of DES.
|
||||
If the
|
||||
.I encrypt
|
||||
argument is non-zero, the routine cipher-block-chain encrypts
|
||||
the cleartext data pointed to by the
|
||||
.I input
|
||||
argument into the ciphertext pointed to by the
|
||||
.I output
|
||||
argument, using the key schedule provided by the
|
||||
.I schedule
|
||||
argument, and initialization vector provided by the
|
||||
.I ivec
|
||||
argument.
|
||||
If the
|
||||
.I length
|
||||
argument is not an integral
|
||||
multiple of eight bytes, the last block is copied to a temp and zero
|
||||
filled (highest addresses). The output is ALWAYS an integral multiple
|
||||
of eight bytes.
|
||||
.PP
|
||||
If
|
||||
.I encrypt
|
||||
is zero, the routine cipher-block chain decrypts the (now) ciphertext
|
||||
data pointed to by the
|
||||
.I input
|
||||
argument into (now) cleartext pointed to by the
|
||||
.I output
|
||||
argument using the key schedule provided by the
|
||||
.I schedule
|
||||
argument, and initialization vector provided by the
|
||||
.I ivec
|
||||
argument. Decryption ALWAYS operates on integral
|
||||
multiples of 8 bytes, so it will round the
|
||||
.I length
|
||||
provided up to the
|
||||
appropriate multiple. Consequently, it will always produce the rounded-up
|
||||
number of bytes of output cleartext. The application must determine if
|
||||
the output cleartext was zero-padded due to original cleartext lengths that
|
||||
were not integral multiples of 8.
|
||||
.PP
|
||||
No errors or meaningful values are returned. Void is not used for
|
||||
compatibility with other compilers.
|
||||
.PP
|
||||
A characteristic of cbc mode is that changing a single bit of the
|
||||
cleartext, then encrypting using cbc mode,
|
||||
affects ALL the subsequent ciphertext. This makes cryptanalysis
|
||||
much more difficult. However, modifying a single bit of the ciphertext,
|
||||
then decrypting, only affects the resulting cleartext from
|
||||
the modified block and the succeeding block. Therefore,
|
||||
.I des_pcbc_encrypt
|
||||
is STRONGLY recommended for applications where
|
||||
indefinite propagation of errors is required in order to detect modifications.
|
||||
.PP
|
||||
.PP
|
||||
.I des_pcbc_encrypt
|
||||
encrypts/decrypts using a modified block chaining mode. Its calling
|
||||
sequence is identical to
|
||||
.I des_cbc_encrypt.
|
||||
It differs in its error propagation characteristics.
|
||||
.PP
|
||||
.I des_pcbc_encrypt
|
||||
is highly recommended for most encryption purposes, in that
|
||||
modification of a single bit of the ciphertext will affect ALL the
|
||||
subsequent (decrypted) cleartext. Similarly, modifying a single bit of
|
||||
the cleartext will affect ALL the subsequent (encrypted) ciphertext.
|
||||
"PCBC" mode, on encryption, "xors" both the
|
||||
cleartext of block N and the ciphertext resulting from block N with the
|
||||
cleartext for block N+1 prior to encrypting block N+1.
|
||||
.PP
|
||||
.I des_cbc_cksum
|
||||
produces an 8 byte cryptographic checksum by cipher-block-chain
|
||||
encrypting the cleartext data pointed to by the
|
||||
.I input
|
||||
argument. All of the ciphertext output is discarded, except the
|
||||
last 8-byte ciphertext block, which is written into the area pointed to by
|
||||
the
|
||||
.I output
|
||||
argument.
|
||||
It uses the key schedule,
|
||||
provided by the
|
||||
.I schedule
|
||||
argument and initialization vector provided by the
|
||||
.I ivec
|
||||
argument.
|
||||
If the
|
||||
.I length
|
||||
argument is not an integral
|
||||
multiple of eight bytes, the last cleartext block is copied to a temp and zero
|
||||
filled (highest addresses). The output is ALWAYS eight bytes.
|
||||
.PP
|
||||
The routine also returns an unsigned long, which is the last (highest address)
|
||||
half of the 8 byte checksum computed.
|
||||
.PP
|
||||
.PP
|
||||
.I quad_cksum
|
||||
produces a checksum by chaining quadratic operations on the cleartext data
|
||||
pointed to by the
|
||||
.I input
|
||||
argument. The
|
||||
.I length
|
||||
argument specifies the length of the
|
||||
input -- only exactly that many bytes are included for the checksum,
|
||||
without any padding.
|
||||
.PP
|
||||
The algorithm may be iterated over the same input data, if the
|
||||
.I out_count
|
||||
argument is 2, 3 or 4, and the optional
|
||||
.I output
|
||||
argument is a non-null pointer .
|
||||
The default is one iteration, and it will not run
|
||||
more than 4 times. Multiple iterations run slower, but provide
|
||||
a longer checksum if desired. The
|
||||
.I seed
|
||||
argument provides an 8-byte seed for the first iteration. If multiple iterations are
|
||||
requested, the results of one iteration are automatically used as
|
||||
the seed for the next iteration.
|
||||
.PP
|
||||
It returns both an unsigned long checksum value, and
|
||||
if the
|
||||
.I output
|
||||
argument is not a null pointer, up to 16 bytes of
|
||||
the computed checksum are written into the output.

.SH DESCRIPTION
|
||||
This library contains a fast implementation of the DES encryption
|
||||
algorithm.
|
||||
.PP
|
||||
There are two phases to the use of DES encryption.
|
||||
The first is the generation of a
|
||||
.I des_key_schedule
|
||||
from a key,
|
||||
the second is the actual encryption.
|
||||
A des key is of type
|
||||
.I des_cblock.
|
||||
This type is made from 8 characters with odd parity.
|
||||
The least significant bit in the character is the parity bit.
|
||||
The key schedule is an expanded form of the key; it is used to speed the
|
||||
encryption process.
|
||||
.PP
|
||||
.I des_read_password
|
||||
writes the string specified by prompt to the standard output,
|
||||
turns off echo and reads an input string from standard input
|
||||
until terminated with a newline.
|
||||
If verify is non-zero, it prompts and reads the input again and verifies
|
||||
that both entered passwords are the same.
|
||||
The entered string is converted into a des key by using the
|
||||
.I des_string_to_key
|
||||
routine.
|
||||
The new key is placed in the
|
||||
.I des_cblock
|
||||
that was passed (by reference) to the routine.
|
||||
If there were no errors,
|
||||
.I des_read_password
|
||||
returns 0,
|
||||
-1 is returned if there was a terminal error and 1 is returned for
|
||||
any other error.
|
||||
.PP
|
||||
.I des_read_2password
|
||||
operates in the same way as
|
||||
.I des_read_password
|
||||
except that it generates 2 keys by using the
|
||||
.I des_string_to_2key
|
||||
function.
|
||||
.PP
|
||||
.I des_read_pw_string
|
||||
is called by
|
||||
.I des_read_password
|
||||
to read and verify a string from a terminal device.
|
||||
The string is returned in
|
||||
.I buf.
|
||||
The size of
|
||||
.I buf
|
||||
is passed to the routine via the
|
||||
.I length
|
||||
parameter.
|
||||
.PP
|
||||
.I des_string_to_key
|
||||
converts a string into a valid des key.
|
||||
.PP
|
||||
.I des_string_to_2key
|
||||
converts a string into 2 valid des keys.
|
||||
This routine is best suited for used to generate keys for use with
|
||||
.I des_3ecb_encrypt.
|
||||
.PP
|
||||
.I des_random_key
|
||||
returns a random key that is made of a combination of process id,
|
||||
time and an increasing counter.
|
||||
.PP
|
||||
Before a des key can be used it is converted into a
|
||||
.I des_key_schedule
|
||||
via the
|
||||
.I des_set_key
|
||||
routine.
|
||||
If the
|
||||
.I des_check_key
|
||||
flag is non-zero,
|
||||
.I des_set_key
|
||||
will check that the key passed is of odd parity and is not a week or
|
||||
semi-weak key.
|
||||
If the parity is wrong,
|
||||
then -1 is returned.
|
||||
If the key is a weak key,
|
||||
then -2 is returned.
|
||||
If an error is returned,
|
||||
the key schedule is not generated.
|
||||
.PP
|
||||
.I des_key_sched
|
||||
is another name for the
|
||||
.I des_set_key
|
||||
function.
|
||||
.PP
|
||||
The following routines mostly operate on an input and output stream of
|
||||
.I des_cblock's.
|
||||
.PP
|
||||
.I des_ecb_encrypt
|
||||
is the basic DES encryption routine that encrypts or decrypts a single 8-byte
|
||||
.I des_cblock
|
||||
in
|
||||
.I electronic code book
|
||||
mode.
|
||||
It always transforms the input data, pointed to by
|
||||
.I input,
|
||||
into the output data,
|
||||
pointed to by the
|
||||
.I output
|
||||
argument.
|
||||
If the
|
||||
.I encrypt
|
||||
argument is non-zero (DES_ENCRYPT),
|
||||
the
|
||||
.I input
|
||||
(cleartext) is encrypted in to the
|
||||
.I output
|
||||
(ciphertext) using the key_schedule specified by the
|
||||
.I schedule
|
||||
argument,
|
||||
previously set via
|
||||
.I des_set_key.
|
||||
If
|
||||
.I encrypt
|
||||
is zero (DES_DECRYPT),
|
||||
the
|
||||
.I input
|
||||
(now ciphertext)
|
||||
is decrypted into the
|
||||
.I output
|
||||
(now cleartext).
|
||||
Input and output may overlap.
|
||||
No meaningful value is returned.
|
||||
.PP
|
||||
.I des_3ecb_encrypt
|
||||
encrypts/decrypts the
|
||||
.I input
|
||||
block by using triple ecb DES encryption.
|
||||
This involves encrypting the input with
|
||||
.I ks1,
|
||||
decryption with the key schedule
|
||||
.I ks2,
|
||||
and then encryption with the first again.
|
||||
This routine greatly reduces the chances of brute force breaking of
|
||||
DES and has the advantage of if
|
||||
.I ks1
|
||||
and
|
||||
.I ks2
|
||||
are the same, it is equivalent to just encryption using ecb mode and
|
||||
.I ks1
|
||||
as the key.
|
||||
.PP
|
||||
.I des_cbc_encrypt
|
||||
encrypts/decrypts using the
|
||||
.I cipher-block-chaining
|
||||
mode of DES.
|
||||
If the
|
||||
.I encrypt
|
||||
argument is non-zero,
|
||||
the routine cipher-block-chain encrypts the cleartext data pointed to by the
|
||||
.I input
|
||||
argument into the ciphertext pointed to by the
|
||||
.I output
|
||||
argument,
|
||||
using the key schedule provided by the
|
||||
.I schedule
|
||||
argument,
|
||||
and initialisation vector provided by the
|
||||
.I ivec
|
||||
argument.
|
||||
If the
|
||||
.I length
|
||||
argument is not an integral multiple of eight bytes,
|
||||
the last block is copied to a temporary area and zero filled.
|
||||
The output is always
|
||||
an integral multiple of eight bytes.
|
||||
To make multiple cbc encrypt calls on a large amount of data appear to
|
||||
be one
|
||||
.I des_cbc_encrypt
|
||||
call, the
|
||||
.I ivec
|
||||
of subsequent calls should be the last 8 bytes of the output.
|
||||
.PP
|
||||
.I des_3cbc_encrypt
|
||||
encrypts/decrypts the
|
||||
.I input
|
||||
block by using triple cbc DES encryption.
|
||||
This involves encrypting the input with key schedule
|
||||
.I ks1,
|
||||
decryption with the key schedule
|
||||
.I ks2,
|
||||
and then encryption with the first again.
|
||||
2 initialisation vectors are required,
|
||||
.I ivec1
|
||||
and
|
||||
.I ivec2.
|
||||
Unlike
|
||||
.I des_cbc_encrypt,
|
||||
these initialisation vectors are modified by the subroutine.
|
||||
This routine greatly reduces the chances of brute force breaking of
|
||||
DES and has the advantage of if
|
||||
.I ks1
|
||||
and
|
||||
.I ks2
|
||||
are the same, it is equivalent to just encryption using cbc mode and
|
||||
.I ks1
|
||||
as the key.
|
||||
.PP
|
||||
.I des_pcbc_encrypt
|
||||
encrypt/decrypts using a modified block chaining mode.
|
||||
It provides better error propagation characteristics than cbc
|
||||
encryption.

|

.I des_cfb_encrypt
|
||||
encrypt/decrypts using cipher feedback mode. This method takes an
|
||||
array of characters as input and outputs and array of characters. It
|
||||
does not require any padding to 8 character groups. Note: the ivec
|
||||
variable is changed and the new changed value needs to be passed to
|
||||
the next call to this function. Since this function runs a complete
|
||||
DES ecb encryption per numbits, this function is only suggested for
|
||||
use when sending small numbers of characters.
|
||||
.PP
|
||||
.I des_ofb_encrypt
|
||||
encrypt using output feedback mode. This method takes an
|
||||
array of characters as input and outputs and array of characters. It
|
||||
does not require any padding to 8 character groups. Note: the ivec
|
||||
variable is changed and the new changed value needs to be passed to
|
||||
the next call to this function. Since this function runs a complete
|
||||
DES ecb encryption per numbits, this function is only suggested for
|
||||
use when sending small numbers of characters.
|
||||
.PP
|
||||
.I des_cbc_cksum
|
||||
produces an 8 byte checksum based on the input stream (via cbc encryption).
|
||||
The last 4 bytes of the checksum is returned and the complete 8 bytes is
|
||||
placed in
|
||||
.I output.
|
||||
.PP
|
||||
.I des_quad_cksum
|
||||
returns a 4 byte checksum from the input bytes.
|
||||
The algorithm can be iterated over the input,
|
||||
depending on
|
||||
.I out_count,
|
||||
1, 2, 3 or 4 times.
|
||||
If
|
||||
.I output
|
||||
is non-NULL,
|
||||
the 8 bytes generated by each pass are written into
|
||||
.I output.
|
||||
.PP
|
||||
.I des_enc_write
|
||||
is used to write
|
||||
.I len
|
||||
bytes
|
||||
to file descriptor
|
||||
.I fd
|
||||
from buffer
|
||||
.I buf.
|
||||
The data is encrypted via
|
||||
.I pcbc_encrypt
|
||||
(default) using
|
||||
.I sched
|
||||
for the key and
|
||||
.I iv
|
||||
as a starting vector.
|
||||
The actual data send down
|
||||
.I fd
|
||||
consists of 4 bytes (in network byte order) containing the length of the
|
||||
following encrypted data. The encrypted data then follows, padded with random
|
||||
data out to a multiple of 8 bytes.
|
||||
.PP
|
||||
.I des_enc_read
|
||||
is used to read
|
||||
.I len
|
||||
bytes
|
||||
from file descriptor
|
||||
.I fd
|
||||
into buffer
|
||||
.I buf.
|
||||
The data being read from
|
||||
.I fd
|
||||
is assumed to have come from
|
||||
.I des_enc_write
|
||||
and is decrypted using
|
||||
.I sched
|
||||
for the key schedule and
|
||||
.I iv
|
||||
for the initial vector.
|
||||
The
|
||||
.I des_enc_read/des_enc_write
|
||||
pair can be used to read/write to files, pipes and sockets.
|
||||
I have used them in implementing a version of rlogin in which all
|
||||
data is encrypted.
|
||||
.PP
|
||||
.I des_rw_mode
|
||||
is used to specify the encryption mode to use with
|
||||
.I des_enc_read
|
||||
and
|
||||
.I des_end_write.
|
||||
If set to
|
||||
.I DES_PCBC_MODE
|
||||
(the default), des_pcbc_encrypt is used.
|
||||
If set to
|
||||
.I DES_CBC_MODE
|
||||
des_cbc_encrypt is used.
|
||||
These two routines and the variable are not part of the normal MIT library.
|
||||
.PP
|
||||
.I des_set_odd_parity
|
||||
sets the parity of the passed
|
||||
.I key
|
||||
to odd. This routine is not part of the standard MIT library.
|
||||
.PP
|
||||
.I des_is_weak_key
|
||||
returns 1 is the passed key is a weak key (pick again :-),
|
||||
0 if it is ok.
|
||||
This routine is not part of the standard MIT library.
|
||||
.PP
|
||||
.I crypt
|
||||
is a replacement for the normal system crypt.
|
||||
It is much faster than the system crypt.
|
||||

|

The encryption routines have been tested on 16bit, 32bit and 64bit
|
||||
machines of various endian and even works under VMS.
|

.PP
|

.SH BUGS
|
||||
.PP
|
||||
If you think this manual is sparse,
|
||||
read the des_crypt(3) manual from the MIT kerberos (or bones outside
|
||||
of the USA) distribution.
|
||||
.PP
|
||||
.I des_cfb_encrypt
|
||||
and
|
||||
.I des_ofb_encrypt
|
||||
operates on input of 8 bits. What this means is that if you set
|
||||
numbits to 12, and length to 2, the first 12 bits will come from the 1st
|
||||
input byte and the low half of the second input byte. The second 12
|
||||
bits will have the low 8 bits taken from the 3rd input byte and the
|
||||
top 4 bits taken from the 4th input byte. The same holds for output.
|
||||
This function has been implemented this way because most people will
|
||||
be using a multiple of 8 and because once you get into pulling bytes input
|
||||
bytes apart things get ugly!
|
||||
.PP
|
||||
.I des_read_pw_string
|
||||
is the most machine/OS dependent function and normally generates the
|
||||
most problems when porting this code.
|
||||
.PP
|
||||
.I des_string_to_key
|
||||
is probably different from the MIT version since there are lots
|
||||
of fun ways to implement one-way encryption of a text string.
|
||||
.PP
|
||||
The routines are optimised for 32 bit machines and so are not efficient
|
||||
on IBM PCs.
|
||||

||||
NOTE: extensive work has been done on this library since this document
|
||||
was origionally written. Please try to read des.doc from the libdes
|
||||
distribution since it is far more upto date and documents more of the
|
||||
functions. Libdes is now also being shipped as part of SSLeay, a
|
||||
general cryptographic library that amonst other things implements
|
||||
netscapes SSL protocoll. The most recent version can be found in
|
||||
SSLeay distributions.

The output has been subject to swaps of the form

0 1 -> 3 1 but the odd and even bits have been put into

2 3 2 0

different words. The main trick is to remember that
|

t=((l>>size)^r)&(mask);
|

r^=t;
|

l^=(t<<size);
|

can be used to swap and move bits between words.

t = 2^16 3^17 -- -- l = 0 1 16 17 r = 2 3 18 19

Thanks for hints from Richard Outerbridge - he told me IP&FP
|
||||
could be done in 15 xor, 10 shifts and 5 ands.
|
||||
When I finally started to think of the problem in 2D
|
||||
I first got ~42 operations without xors. When I remembered
|
||||
how to use xors :-) I got it to its final state.

0 1 -> 3 1 but the odd and even bits have been put into

t=((l>>size)^r)&(mask);

r^=t;

l^=(t<<size);

can be used to swap and move bits between words.

Thanks for hints from Richard Outerbridge - he told me IP&FP
|

could be done in 15 xor, 10 shifts and 5 ands.
|

When I finally started to think of the problem in 2D
|

I first got ~42 operations without xors. When I remembered
|
||||
how to use xors :-) I got it to its final state.
