Proposal for "Crypt_Blowfish"

» Description

Crypt_Blowfish

Crypt_Blowfish allows for fast two-way encryption using Bruce Schneier's Blowfish algorithm. The encryption is done purely in PHP, therefore Crypt_Blowfish does not require the Mcrypt PHP extension.

Example Usage


<?php

$bf = new Crypt_Blowfish();
$encrypted = $bf->encrypt('this is some example plain text');
$plainText = $bf->decrypt($encrypted);
?>

Crypt_Blowfish can also preform encryption based on a specified key.


<?php

$bf = new Crypt_Blowfish('some secret key!');
$encrypted = $bf->encrypt('this is some example plain text');
$plainText = $bf->decrypt($encrypted);
?>

    • removed @ wrapper from ord
    • added class Crypt_Blowfish_Default_Key which contains the default key
    • Crypt_Blowfish now initializes using Crypt_Blowfish_Default_Key object

    • setKey() method now takes optional $key parameter. If $key is given, it will set the secret key to $key. If no parameters, it will reset to the default key

    • updated to better follow coding standards
    • renamed Crypt_Blowfish_Default_Key class to Crypt_Blowfish_DefaultKey
    • includes default key when needed

    • Greatly increased speed of encryption
    • Inlined function _F()
    • Replaced ord/chr calls with cleaner and faster pack/unpack (Thanks to Ant Aasma for the speed optimizations)
