📛 NAME

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

🚀 Quick Reference

🔧 Use Case	💻 Command	📝 Description
Encrypt with CBC (recommended)	my $cbc = Crypt::Mode::CBC->new('Camellia'); $ciphertext = $cbc->encrypt($data, $key, $iv);	Efficient CBC mode encryption via Crypt::Mode::CBC
Encrypt via legacy Crypt::CBC	my $cbc = Crypt::CBC->new( -cipher=>'Cipher::Camellia', -key=>$key, -iv=>$iv ); $ciphertext = $cbc->encrypt($data);	Slower, but compatible with older code
Decrypt data	$plaintext = $cbc->decrypt($ciphertext);	Reverse encryption
Get cipher block size	$bs = Crypt::Cipher::Camellia->blocksize;	Always 16 bytes
Check key sizes	$min = Crypt::Cipher::Camellia->min_keysize; $max = Crypt::Cipher::Camellia->max_keysize;	128, 192, 256 bits
Create cipher with rounds	$c = Crypt::Cipher::Camellia->new($key, $rounds);	Optional custom round count

📋 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).
