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.
