# 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);
|
||||
|
||||
# The following 8 arrays are used in des_set_key
