Crypt::Cipher::Serpent(3p)

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

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

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

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

DESCRIPTION
This module implements the Serpent 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
 $c = Crypt::Cipher::Serpent->new($key);
 #or
 $c = Crypt::Cipher::Serpent->new($key, $rounds);
