96 This library contains a fast implementation of the DES encryption
97 algorithm.
98 There are two phases to the use of DES encryption. The first is the
100 generation of a DES_key_schedule from a key, the second is the actual
101 encryption. A DES key is of type DES_cblock. This type consists of 8
102 bytes with odd parity. The least significant bit in each byte is the
103 parity bit. The key schedule is an expanded form of the key; it is
104 used to speed the encryption process.
105 DES_random_key() generates a random key. The random generator must be
107 seeded when calling this function. If the automatic seeding or
108 reseeding of the OpenSSL CSPRNG fails due to external circumstances
109 (see RAND(7)), the operation will
