=head1 NAME

Crypt::Cipher::IDEA - Symmetric cipher IDEA, key size: 128 bits (Crypt::CBC compliant)

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

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

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

=head1 DESCRIPTION

This module implements the IDEA cipher. Provided interface is compliant with L<Crypt::CBC|Crypt::CBC> module.

B<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
L<Crypt::Mode::CBC|Crypt::Mode::CBC>, L<Crypt::Mode::CTR|Crypt::Mode::CTR> or L<Crypt::CBC|Crypt::CBC> (which will be slower).
