Blowfish Encryption to Match PHP's Mcrypt Extension

Demonstrates how to match Blowfish encryption results with PHP's mcrypt extension.

Please refer to this PHP (non-Chilkat) example for PHP Blowfish Encryption. The code here matches the PHP mcrypt results on that page.

    //  multiple of 8.

    crypt.put_PaddingScheme(3);

    //  encryption, and the input for decryption.
    //  It may be "hex", "url", "base64", or "quoted-printable".
