Crypt::Cipher::Serpent - phpMan

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).
