NAME

       Crypt::Anubis - Crypt::CBC-compliant block cipher

ABSTRACT

       Anubis is a variable-length key, 128-bit block cipher designed by Vin-
       cent Rijmen and Paulo S. L. M. Barreto.

SYNOPSIS

           use Crypt::Anubis;

           $cipher = new Crypt::Anubis $key;
           $ciphertext = $cipher->encrypt($plaintext);
           $plaintext  = $cipher->decrypt($ciphertext);

DESCRIPTION

       Anubis is a variable-length key, 128-bit block cipher designed by Vin-
       cent Rijmen and Paulo S. L. M. Barreto. Key length can be 128, 160,
       192, 224, 256, 288, or 320 bits. The default key length used in this
       implementation is 128 bits (16 bytes).

       This module supports the Crypt::CBC interface, with the following func-
       tions.

       Functions

       blocksize
           Returns the size (in bytes) of the block (16, in this case).

       keysize
           Returns the size (in bytes) of the key (16, in this case).

       encrypt($data)
           Encrypts 16 bytes of $data and returns the corresponding cipher-
           text.

       decrypt($data)
           Decrypts 16 bytes of $data and returns the corresponding plaintext.

EXAMPLE 1

           #!/usr/local/bin/perl

           use diagnostics;
           use strict;
           use warnings;
           use Crypt::Anubis;

           # key must be 16 bytes long
           my $key = "0123456789abcdef";

           my $cipher = new Crypt::Anubis $key;

           print "blocksize = ", $cipher->blocksize, " bytes \n";
           print "keysize = ", $cipher->keysize, " bytes \n";

           # block must be 16 bytes long
           my $plaintext1 = "0123456789abcdef";

           my $ciphertext = $cipher->encrypt($plaintext1);
           my $plaintext2 = $cipher->decrypt($ciphertext);

           print "Decryption OK\n" if ($plaintext1 eq $plaintext2);

EXAMPLE 2

           #!/usr/local/bin/perl

           use diagnostics;
           use strict;
           use warnings;
           use Crypt::CBC;  # CBC automatically loads Anubis for us

           # when using Crypt::CBC, key may be of ANY length
           my $key = "0123456789abcdef";

           # IV must be exactly 16 bytes long
           my $IV = pack "H32", 0;

           my $cipher = Crypt::CBC->new({'key' => $key,
                                         'cipher' => 'Anubis',
                                         'iv' => $IV,
                                         'regenerate_key' => 1,
                                         'padding' => 'standard',
                                         'prepend_iv' => 0
                                       });

           # when using Crypt::CBC, plaintext may be of ANY length
           my $plaintext1 = "This is a test";

           my $ciphertext = $cipher->encrypt($plaintext1);
           my $plaintext2 = $cipher->decrypt($ciphertext);

           print "Decryption OK\n" if ($plaintext1 eq $plaintext2);
