 There are two phases to the use of DES encryption.  The first is the
 generation of a I<DES_key_schedule> from a key, the second is the
-actual encryption.  A DES key is of type I<DES_cblock>. This type is

 consists of 8 bytes with odd parity.  The least significant bit in
 each byte is the parity bit.  The key schedule is an expanded form of
 the key; it is used to speed the encryption process.
