NAME

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

VERSION

version 0.004

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,
  );

  say unpack("H*",$crypt->encrypt(pack("H*","0ABC0F2241535345631FCE")));            # Output F64F2268BF6185A16DADEFD7378E5CE5
  say unpack("H*",$crypt->decrypt(pack("H*","F64F2268BF6185A16DADEFD7378E5CE5")));  # Output 0ABC0F2241535345631FCE0000000000

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 change this value from your program.

cipher2

second Crypt::DES Cipher object generated from the key. This is built automatically. Do not change this value from your program.

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
