NAME    [Toc]    [Back]

       encrypt - Encrypt 64 bits messages

SYNOPSIS    [Toc]    [Back]

       #define _XOPEN_SOURCE

       #include <unistd.h>

       void encrypt(char block[64], int edflag);
       void setkey(const char *key);

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       These functions do not return any value.
