NAME
encrypt - Encrypt 64 bits messagesSYNOPSIS
#define _XOPEN_SOURCE#include <unistd.h>
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.
