🏷️ NAME

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

🚀 Quick Reference

📜 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).

🛠️ METHODS

• $c = Crypt::Cipher::Camellia->new($key);
$c = Crypt::Cipher::Camellia->new($key, $rounds); — Create a new cipher object. $key length must match one of the allowed sizes (128, 192, or 256 bits). Optional $rounds parameter overrides the default round count.
• $ciphertext = $c->encrypt($plaintext); — Encrypts a single block (16 bytes) of data and returns the ciphertext.
• $plaintext = $c->decrypt($ciphertext); — Decrypts a single block and returns the plaintext.
• $c->keysize; / Crypt::Cipher::Camellia->keysize; / Crypt::Cipher::Camellia::keysize; — Returns the key size in bytes for the current object or class.
• $c->blocksize; / Crypt::Cipher::Camellia->blocksize; / Crypt::Cipher::Camellia::blocksize; — Returns the block size (always 16 bytes).
• $c->max_keysize; / Crypt::Cipher::Camellia->max_keysize; / Crypt::Cipher::Camellia::max_keysize; — Returns the maximum supported key size (32 bytes).
• $c->min_keysize; / Crypt::Cipher::Camellia->min_keysize; / Crypt::Cipher::Camellia::min_keysize; — Returns the minimum supported key size (16 bytes).
• $c->default_rounds; / Crypt::Cipher::Camellia->default_rounds; / Crypt::Cipher::Camellia::default_rounds; — Returns the default number of rounds used by the cipher.
