encrypt - Encrypt 64 bits messages
!!SYNOPSIS


__#define _XOPEN_SOURCE__


__#include __


__void encrypt(char__ ''block''__[[64], int__
''edflag''__);
void setkey(const char *__''key''__);__
!!DESCRIPTION


These functions encrypt and decrypt 64 bit messages. The
setkey() function sets the key used by encrypt(). The
''key'' parameter used here is an array of bytes, having
each byte the numerical value 1 or 0. The key[[n] byte, where
n=8*q-1, is ignored consisting the key used of 56
bits.


The setkey() function modifies the passed buffer, encoding
if ''edflag'' is 0, and decoding if 1 is being
passed.


These functions are not reentrant.
!!RETURN VALUE


These functions do not return any value.
