6 Crypt::Cipher::MULTI2 - Symetric cipher MULTI2, key size: 320 bits
7 (Crypt::CBC compliant)
8
10 ### example 1
11 use Crypt::Mode::CBC;
12
13 my $key = '...'; # length has to be valid key size for this cipher
14 my $iv = '...'; # 16 bytes
15 my $cbc = Crypt::Mode::CBC->new('MULTI2');
16 my $ciphertext = $cbc->encrypt("secret data", $key, $iv);
17
18 ### example 2 (slower)
19 use Crypt::CBC;
20 use Crypt::Cipher::MULTI2;
21
22 my $key = '...'; # length has to be valid key size for this cipher
23 my $iv = '...'; # 16 bytes
24 my $cbc = Crypt::CBC->new( -cipher=>'Cipher::MULTI2', -key=>$key, -iv=>$iv );
25 my $ciphertext = $cbc->encrypt("secret data");

28 This module implements the MULTI2 cipher. Provided interface is
29 compliant with Crypt::CBC module.
30
31 BEWARE: This module implements just elementary
32 "one-block-(en|de)cryption" operation - if you want to encrypt/decrypt
33 generic data you have to use some of the cipher block modes - check for
34 example Crypt::Mode::CBC, Crypt::Mode::CTR or Crypt::CBC (which will be
35 slower).
