XCRYPT(3)						     Linux Programmer's Manual							 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.

VERSIONS

       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.
