xcrypt(3R)                                             xcrypt(3R)



NAME
     xcrypt, xdecrypt, passwd2des - hex encryption and utility
     routines

SYNOPSIS
     xencrypt(data, key)
          char *data;
          char *key;

     xdecrypt(data, key)
          char *data;
          char *key;

     passwd2des(pass, key)
          char *pass;
          char *key;

DESCRIPTION
     The routines xencrypt and xdecrypt take NULL-terminated hex-
     adecimal strings as arguments, and encrypt them using the
     8-byte key as input to the DES algorithm. The input strings
     must have a length that is a multiple on 16 hex digits (64
     bits is the DES block size).

     passwd2des converts a password, of arbitrary length, into an
     8-byte DES key, with odd-parity set in the low bit of each
     byte. The high-order bit of each input byte is ignored.

     These routines are used by the DES authentication subsystem
     for encrypting and decrypting the secret keys stored in the
     publickey database.
