📛 NAME

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

🚀 Quick Reference

Use Case	Command	Description
🔐 Create a CBC cipher	my $cbc = Crypt::Mode::CBC->new('Khazad');	Instantiate CBC mode with Khazad
🔏 Encrypt data	$ciphertext = $cbc->encrypt("secret", $key, $iv);	Encrypt using a 128-bit key and 16-byte IV
🔓 Decrypt data	$plaintext = $cbc->decrypt($ciphertext, $key, $iv);	Decrypt back to plaintext
⚙️ Get key size info	$c->keysize; or Crypt::Cipher::Khazad->keysize;	Returns 16 (128 bits)
📦 Block size	$c->blocksize;	Always 16 bytes

📖 SYNOPSIS

Example 1 ✅ (recommended, fast)

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

Example 2 🐢 (slower, legacy)

use Crypt::CBC;
use Crypt::Cipher::Khazad;

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

📝 DESCRIPTION

This module implements the Khazad 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).
