NAME
Crypt::Cipher::Camellia - Symmetric cipher Camellia, key size: 128/192/256 bits (Crypt::CBC compliant)
SYNOPSIS
### example 1
use Crypt::Mode::CBC;
my $key = '...'; # length has to be valid key size for this cipher
my $iv = '...'; # 16 bytes
my $cbc = Crypt::Mode::CBC->new('Camellia');
my $ciphertext = $cbc->encrypt("secret data", $key, $iv);
### example 2 (slower)
use Crypt::CBC;
use Crypt::Cipher::Camellia;
my $key = '...'; # length has to be valid key size for this cipher
my $iv = '...'; # 16 bytes
my $cbc = Crypt::CBC->new( -cipher=>'Cipher::Camellia', -key=>$key, -iv=>$iv );
my $ciphertext = $cbc->encrypt("secret data");DESCRIPTION
This module implements the Camellia cipher. Provided interface is compliant with Crypt::CBC module.
BEWARE: This module implements just elementary "one-block-(en|de)cryption" operation - if you want to encrypt/decrypt generic data you have to use some of the cipher block modes - check for example Crypt::Mode::CBC, Crypt::Mode::CTR or Crypt::CBC (which will be slower).
