NAMECrypt::Anubis - Crypt::CBC-compliant block cipher ABSTRACTAnubis is a variable-length key, 128-bit block cipher designed by Vincent Rijmen and Paulo S. L. M. Barreto. SYNOPSISuse Crypt::Anubis; $cipher = new Crypt::Anubis $key; $ciphertext = $cipher->encrypt($plaintext); $plaintext = $cipher->decrypt($ciphertext); DESCRIPTIONAnubis is a variable-length key, 128-bit block cipher designed by Vincent 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 functions. Functions
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); MORE EXAMPLESSee Crypt::CBC for more examples using CBC mode.
