NAME

Crypt::RC5 - Perl implementation of the RC5 encryption algorithm.

CONTENTS

SYNOPSIS



  use Crypt::RC5;

  $ref = Crypt::RC5->new( $key, $rounds );
  $ciphertext = $ref->encrypt( $plaintext );

  $ref2 = Crypt::RC5->new( $key, $rounds );
  $plaintext2 = $ref2->decrypt( $ciphertext );



DESCRIPTION

RC5 is a fast block cipher designed by Ronald Rivest for RSA Data Security (now RSA Security) in 1994. It is a parameterized algorithm with a variable block size, a variable key size, and a variable number of rounds. This particular implementation is 32 bit. As such, it is suggested that a minimum of 12 rounds be performed.

Core logic based on RC5 in 6 lines of perl at http://www.cypherspace.org
