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).
