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
       WARNING: Do not use these functions in new code.  They do not achieve any type of acceptable cryptographic security guarantees.

       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 functions are available in glibc since version 2.1.
