NAME

Crypt::MCrypt - Perl interface for libmcrypt C library.

VERSION

version 0.07

SYNOPSIS

    use Crypt::MCrypt;

    my $iv = pack("H*","0000000000000000");
    my $key = pack("H*","1234567890123456" . "7890123456789012" . "1234567890123456");
    my $cipher_text = pack("H*","E9FF3161EE05ABC9" 
        . "7ea3cacb991318aa" 
        . "585379599b0eaabb" 
        . "c4e474ead1956f47" 
        . "6755f13f1af5235d");
    my $algorithm = "tripledes";
    my $mode = "cbc";
    my $obj = Crypt::MCrypt->new(
        algorithm => $algorithm, 
        mode      => $mode,
        key       => $key, 
        iv        => $iv,
    );
    my $plain_text = $obj->decrypt($cipher_text);
    print "\nPLAIN: $plain_text\n";
    print "\nPLAIN in hex: " . unpack("H*",$plain_text) . "\n";
    $cipher_text = $obj->encrypt($plain_text);
    print "\nCIPHER: $cipher_text\n";
    print "\nCIPHER in hex: " . unpack("H*",$cipher_text) . "\n";

DESCRIPTION

This is a perl interface to libmcrypt c library. It exposes the crypto functions provided by the libmcrypt library in a perl interface with a binding code that accounts for null C strings in ciphertext or plain text.

ATTRIBUTES

algorithm

contains the name of the algorithm used to decrypt encrypt blocks of data

mode

contains the name of the block cipher mode of operation used to encrypt/decrypt blocks of data.

key

contains the key for the encryption decryption algorithm

Initialization Vector

contains the Initialization for the first block of data in block cipher mode of operation.

METHODS

$self->decrypt($ciphertext)

decrypt blocks of ciphertext

$self->encrypt($ciphertext)

encrypt blocks of data

USAGE

  • This module provides a object oriented interface to the libmcrypt library. It uses Mo, a scaled down version of Moose without any data checks to improve speed.
