-# Copyright (C) 1993 Eric Young
-#
-# 11 April 1996 - patched to circumvent Perl 5 (through 5.002) problem
-#                 with sign-extension on right shift operations.
-#                 Ed Kubaitis - ejk@uiuc.edu
-#
-# eay - 92/08/31 - I think I have fixed all problems for 64bit
-# versions of perl but I could be wrong since I have not tested it yet :-).
-#
-# This is an implementation of DES in perl.
-# The two routines (des_set_key and des_ecb_encrypt)
-# take 8 byte objects as arguments.
-#
-# des_set_key takes an 8 byte string as a key and returns a key schedule
-# for use in calls to des_ecb_encrypt.
-# des_ecb_encrypt takes three arguments, the first is a key schedule
-# (make sure to pass it by reference with the *), the second is 1
-# to encrypt, 0 to decrypt.  The third argument is an 8 byte object
-# to encrypt.  The function returns an 8 byte object that has been
-# DES encrypted.
-#
-# example:
-# require 'des.pl'
-#
-# $key =pack("C8",0x12,0x23,0x45,0x67,0x89,0xab,0xcd,0xef);
-# @ks=  &des_set_key($key);
-#
-# $outbytes= &des_ecb_encrypt(*ks,1,$data);
-# @enc =unpack("C8",$outbytes);
-#
-                 
-package des;
-
-eval("use integer;") if (int($]) > 4);
