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.
