106 This library contains a fast implementation of the DES encryption
107 algorithm.
108 There are two phases to the use of DES encryption. The first is the
110 generation of a DES_key_schedule from a key, the second is the actual
111 encryption. A DES key is of type DES_cblock. This type is consists of
112 8 bytes with odd parity. The least significant bit in each byte is the
113 parity bit. The key schedule is an expanded form of the key; it is
114 used to speed the encryption process.
115 DES_random_key() generates a random key. The PRNG must be see
