🏷️ NAME

Crypt::Cipher::Noekeon - Symmetric cipher Noekeon, key size: 128 bits

🚀 Quick Reference

Use Case	Command	Description
Encrypt with CBC mode	$cbc->encrypt("data", $key, $iv)	Encrypt data using Noekeon in CBC mode (fast)
Encrypt with Crypt::CBC	$cbc->encrypt("data")	Encrypt via Crypt::CBC (slower, more flexible)
Create cipher object	Crypt::Cipher::Noekeon->new($key)	Initialize Noekeon cipher with 128‑bit key
Get key/block sizes	$c->keysize $c->blocksize	Query key size (16 bytes) and block size (16 bytes)

📝 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('Noekeon');
my $ciphertext = $cbc->encrypt("secret data", $key, $iv);

### example 2 (slower)
use Crypt::CBC;
use Crypt::Cipher::Noekeon;

my $key = '...'; # length has to be valid key size for this cipher
my $iv = '...';  # 16 bytes
my $cbc = Crypt::CBC->new( -cipher=>'Cipher::Noekeon', -key=>$key, -iv=>$iv );
my $ciphertext = $cbc->encrypt("secret data");

📖 DESCRIPTION

This module implements the Noekeon 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).

🔧 METHODS

• new($key)
new($key, $rounds) — Create a new Noekeon cipher object
• encrypt($plaintext) — Encrypt a single block
• decrypt($ciphertext) — Decrypt a single block
• keysize() — Returns the required key size (16 bytes)
• blocksize() — Returns the block size (16 bytes)
• max_keysize() — Maximum key size supported
• min_keysize() — Minimum key size supported
• default_rounds() — Default number of rounds
