NAME

Crypt::TripleDES::CBC - Triple DES in CBC mode Pure implementation

VERSION

version 0.002

SYNOPSIS

   use Crypt::TripleDES::CBC;
 
   my $key = pack("H*"
     , "1234567890123456"
     . "7890123456789012");
   my $iv = pack("H*","0000000000000000");
   my $crypt = Crypt::TripleDES::CBC->new(
     key => $key,
     iv  => $iv,
   );
 
   $crypt->encrypt(pack("H*","0ABC0F2241535345631FCE"));
   $crypt->decrypt(pack("H*","0ABC0F2241535345631FCE"));

DESCRIPTION

Most Modules on CPAN don't do a standards compliant implementation, while they are able to decrypt what they encrypt. There are corner cases where certain blocks of data in a chain don't decrypt properly. This is (almost)a pure perl implementation of TripleDES in CBC mode using Crypt::DES to encrypt individual blocks.

ATTRIBUTES

cipher1

First Crypt::DES Cipher object generated from the key. This is built automatically. Do not set the manually.

cipher2

second Crypt::DES Cipher object generated from the key. This is built automatically. Do not set the manually.

key

Encryption Key this must be ascii packed string as shown in Synopsis.

iv

Initialization vector, default is a null string.

METHODS

encrypt

Encryption Method

decrypt

Decryption method
