📖 NAME

Crypt::Cipher::Camellia - Symmetric cipher Camellia, key size: 128/192/256 bits

🚀 Quick Reference

Use Case	Command	Description
🔐 Encrypt with CBC mode	$cbc = Crypt::Mode::CBC->new('Camellia'); $ciphertext = $cbc->encrypt($data, $key, $iv);	Encrypt arbitrary data using Camellia cipher in CBC mode (recommended)
🔓 Decrypt with CBC mode	$plaintext = $cbc->decrypt($ciphertext, $key, $iv);	Decrypt data previously encrypted with CBC mode
🔑 Create cipher object	$c = Crypt::Cipher::Camellia->new($key);	Construct a new Camellia cipher object for single-block operations
🔒 Encrypt single block	$ciphertext = $c->encrypt($plaintext);	Encrypt one 16-byte block of plaintext
🔓 Decrypt single block	$plaintext = $c->decrypt($ciphertext);	Decrypt one 16-byte block of ciphertext
📏 Get key size	$c->keysize; # or Crypt::Cipher::Camellia->keysize;	Return the key size in bytes (16, 24, or 32)
📦 Get block size	$c->blocksize; # or Crypt::Cipher::Camellia->blocksize;	Return the block size in bytes (always 16)

📋 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).
