Crypt::Cipher::MULTI2(3)

NAME
Crypt::Cipher::MULTI2 - Symmetric cipher MULTI2, key size: 320 bits

SYNOPSIS
  ### example 1
  use Crypt::Mode::CBC;

  my $key = '...'; # length has to be valid key size for this cipher
  my $iv = '...';  # 16 bytes
  my $cbc = Crypt::Mode::CBC->new('MULTI2');
  my $ciphertext = $cbc->encrypt("secret data", $key, $iv);

  ### example 2 (slower)
  use Crypt::CBC;
  use Crypt::Cipher::MULTI2;

  my $key = '...'; # length has to be valid key size for this cipher
  my $iv = '...';  # 16 bytes
  my $cbc = Crypt::CBC->new( -cipher=>'Cipher::MULTI2', -key=>$key, -iv=>$iv );
  my $ciphertext = $cbc->encrypt("secret data");

DESCRIPTION
This module implements the MULTI2 cipher. Provided interface is compliant with Crypt::CBC module.

BEWARE: This module implements just elementary "one-block-(en|de)cryption" operation - if you want to encrypt/decrypt generic data you have to use some of the cipher block modes - check for example Crypt::Mode::CBC, Crypt::Mode::CTR or Crypt::CBC (which will be slower).

METHODS

  new
