Version 3.23 11/04/95
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
