NAME
       Crypt::RC6 - Crypt::CBC compliant RC6 block cipher encryption module

SYNOPSIS
           use Crypt::RC6;

           my $cipher = new Crypt::RC6 $key;

           my $ciphertext = $cipher->encrypt($plaintext);
           my $plaintext = $cipher->decrypt($ciphertext);

DESCRIPTION
       From THE RC6 BLOCK CIPHER, by Rivest, Robshaw, Sidney, and Yin...

       "RC6 is an evolutionary improvement of RC5, designed to meet the
       requirements of the Advanced Encryption Standard (AES). Like RC5, RC6
       makes essential use of data-dependent rotations. New features of RC6
       include the use of four working registers instead of two, and the
       inclusion of integer multiplication as an additional primitive opera-
       tion. The use of multiplication greatly increases the diffusion
       achieved per round, allowing for greater security, fewer rounds, and
       increased throughput."

       This implementation requires the use of a 16-, 24-, or 32-byte key and
       16-byte blocks for encryption/decryption. Twenty rounds are performed.

       I am indebted to Marc Lehmann, the author of the "Crypt::Twofish2" mod-
       ule, as I used his code as a guide.
