xcrypt(3)                      RPC cryptography                      xcrypt(3)



NAME
       xencrypt, xdecrypt, passwd2des - RFS password encryption

SYNOPSIS
       #include <rpc/des_crypt.h>

       void passwd2des (char *passwd, char *key);

       int xencrypt (char *secret, char *passwd);

       int xdecrypt (char *secret, char *passwd);


DESCRIPTION
       The  function  passwd2des() takes a character string passwd of arbitrary length and
       fills a character array key of length 8. The array key is suitable for use  as  DES
       key.  It  has odd parity set in bit 0 of each byte.  Both other functions described
       here use this function to turn their argument passwd into a DES key.

       The xencrypt() function takes the ASCII character string secret given in hex, which
       must  have a length that is a multiple of 16, encrypts it using the DES key derived
       from passwd by passwd2des(), and outputs the result again in secret as a hex string
       of the same length.

       The xdecrypt() function performs the converse operation.

RETURN VALUE
       The functions xencrypt() and xdecrypt() return 1 on success and 0 on error.

AVAILABILITY
       These routines are present in libc 4.6.27 and later, and in glibc 2.1 and later.

BUGS
       The prototypes are missing from the abovementioned include file.
