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

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).
