NAME

6       Crypt::Cipher::SAFER_SK64 - Symetric cipher SAFER_SK64, key size: 64
7       bits (Crypt::CBC compliant)
8

SYNOPSIS

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('SAFER_SK64');
16         my $ciphertext = $cbc->encrypt("secret data", $key, $iv);
17
18         ### example 2 (slower)
19         use Crypt::CBC;
20         use Crypt::Cipher::SAFER_SK64;
21
22         my $key = '...'; # length has to be valid key size for this cipher
23         my $iv = '...';  # 16 bytes
24         my $cbc = Crypt::CBC->new( -cipher=>'Cipher::SAFER_SK64', -key=>$key, -iv=>$iv );
25         my $ciphertext = $cbc->encrypt("secret data");

DESCRIPTION

28       This module implements the SAFER_SK64 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).
