NAME

6       Crypt::Cipher::Khazad - Symmetric cipher Khazad, key size: 128 bits
7

SYNOPSIS

9         ### example 1
10         use Crypt::Mode::CBC;
11
12         my $key = '...'; # length has to be valid key size for this cipher
13         my $iv = '...';  # 16 bytes
14         my $cbc = Crypt::Mode::CBC->new('Khazad');
15         my $ciphertext = $cbc->encrypt("secret data", $key, $iv);
16
17         ### example 2 (slower)
18         use Crypt::CBC;
19         use Crypt::Cipher::Khazad;
20
21         my $key = '...'; # length has to be valid key size for this cipher
22         my $iv = '...';  # 16 bytes
23         my $cbc = Crypt::CBC->new( -cipher=>'Cipher::Khazad', -key=>$key, -iv=>$iv );
24         my $ciphertext = $cbc->encrypt("secret data");
25

DESCRIPTION

27       This module implements the Khazad cipher. Provided interface is
28       compliant with Crypt::CBC module.
29
30       BEWARE: This module implements just elementary
31       "one-block-(en|de)cryption" operation - if you want to encrypt/decrypt
32       generic data you have to use some of the cipher block modes - check for
33       example Crypt::Mode::CBC, Crypt::Mode::CTR or Crypt::CBC (which will be
34       slower).
