This kit builds a DES encryption library and a DES encryption program.
It suports ecb, cbc, ofb, cfb, triple ecb, triple cbc and MIT's pcbc
encryption modes and also has a fast implementation of crypt(3).
It supports ecb, cbc, ofb, cfb, triple ecb, triple cbc, triple ofb,
triple cfb, 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 arbitary length string,
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

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
