NAME
       Crypt::Cipher::Skipjack - Symmetric cipher Skipjack, key size: 80 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('Skipjack');
         my $ciphertext = $cbc->encrypt("secret data", $key, $iv);

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

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

DESCRIPTION
       This module implements the Skipjack 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
        $c = Crypt::Cipher::Skipjack->new($key);

   encrypt
        $ciphertext = $c->encrypt($plaintext);

   decrypt
        $plaintext = $c->decrypt($ciphertext);
