|
||
|
|
|
||
|
|
Crypt::Cipher::Twofish - Symetric cipher Twofish, key size: 128/192/256 bits (Crypt::CBC compliant)
|
||
|
|
|
||
|
|
=head1 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('Twofish');
|
||
|
|
my $ciphertext = $cbc->encrypt("secret data", $key, $iv);
|
||
|
|
|
||
|
|
### example 2
|
||
|
|
use Crypt::CBC;
|
||
|
|
use Crypt::Cipher::Twofish;
|
||
|
|
|
||
|
|
my $key = '...'; # length has to be valid key size for this cipher
|
||
|
|
my $iv = '...'; # 16 bytes
|
||
|
|
my $cbc = Crypt::CBC->new( -cipher=>'Cipher::Twofish', -key=>$key, -iv=>$iv );
|
||
|
|
my $ciphertext = $cbc->encrypt("secret data");

=head1 DESCRIPTION
|
||
|
|
|
||
|
|
This module implements the Twofish cipher. Provided interface is compliant with L<Crypt::CBC|Crypt::CBC> module.
|
||
|
|
|
||
|
|
B<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
|
||
|
|
L<Crypt::Mode::CBC|Crypt::Mode::CBC>, L<Crypt::Mode::CTR|Crypt::Mode::CTR> or L<Crypt::CBC|Crypt::CBC> (which will be slower).
