23 encrypts and decrypts data using the
24 Data Encryption Standard algorithm.
29 Two standard encryption modes are supported by the
32 program, Cipher Block Chaining (the default) and Electronic Code Book
38 If the key is an argument to the
41 command, it is potentially visible to users executing
43 or a derivative. To minimise this possibility,
46 takes care to destroy the key argument immediately upon entry.

50 options are used, the key conversion procedure will not be compatible
51 with the sunOS des(1) version but will use all the user supplied
52 character to generate the des key.
55 command reads from standard input unless
57 is specified and writes to standard output unless
59 will be embedded in the header.
