-The functions,
-.Fn encrypt ,
-.Fn setkey ,
-.Fn des_setkey
-and
-.Fn des_cipher
-provide access to the
-.Tn DES
-algorithm itself.
-.Fn setkey
-is passed a 64-byte array of binary values (numeric 0 or 1).
-A 56-bit key is extracted from this array by dividing the
-array into groups of 8, and ignoring the last bit in each group.
-That bit is reserved for a byte parity check by DES, but is ignored
-by these functions.
-.Pp
-The
-.Fa block
-argument to
-.Fn encrypt
-is also a 64-byte array of binary values.
-If the value of
-.Fa flag
-is 0,
-.Fa block
-is encrypted otherwise it is decrypted.
-The result is returned in the original array
-.Fa block
-after using the key specified by
-.Fn setkey
-to process it.
-.Pp
-The argument to
-.Fn des_setkey
-is a character array of length 8.
-The least significant bit (the parity bit) in each character is ignored,
-and the remaining bits are concatenated to form a 56-bit key.
-The function
-.Fn des_cipher

-is negative) the 64-bits stored in the 8 characters at

The function
.Fn crypt
returns a pointer to the encrypted value on success, and NULL on failure.
-The functions
-.Fn setkey ,
