=head1 NAME

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

=head1 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-&gt;new('XTEA');
  my $ciphertext = $cbc-&gt;encrypt("secret data", $key, $iv);

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

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

=head1 DESCRIPTION

This module implements the XTEA cipher. Provided interface is compliant with L&lt;Crypt::CBC|Crypt::CBC&gt; module.

B&lt;BEWARE:&gt; 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
L&lt;Crypt::Mode::CBC|Crypt::Mode::CBC&gt;, L&lt;Crypt::Mode::CTR|Crypt::Mode::CTR&gt; or L&lt;Crypt::CBC|Crypt::CBC&gt; (which will be slower).
