-.Pp
-The functions
-.Fn encrypt ,
-.Fn setkey ,
-.Fn des_setkey ,
-and
-.Fn des_cipher
-provide access to the
-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
-encrypts (or decrypts if
-.Fa count
-is negative) the 64-bits stored in the 8 characters at
-.Fa in
-using
-.Xr abs 3
-of
-.Fa count
-iterations of DES
-and stores the 64-bit result in the 8 characters at
-.Fa out
-(which may be the same as
-.Fa in ) .
-The
-.Fa salt
-specifies perturbations to the DES
-E-box output as described above.
-.Pp
-The
-.Fn crypt ,
-.Fn setkey ,
-and
-.Fn des_setkey
-functions all manipulate the same key space.
 .Sh RETURN VALUES
 The function
 .Fn crypt
 returns a pointer to the encrypted value on success, and
 .Dv NULL
 on failure.
-The functions
-.Fn setkey ,
-.Fn encrypt ,
-.Fn des_setkey ,
-and
-.Fn des_cipher
-return 0 on success and 1 on failure.
