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.

    //  CipherMode may be "ecb" or "cbc"
    crypt.put_CipherMode("cbc");

    //  KeyLength (in bits) may be a number between 32 and 448.
    //  128-bits is usually sufficient.  The KeyLength must be a
    //  multiple of 8.
    crypt.put_KeyLength(256);

    //  Pad with NULL bytes (PHP pads with NULL bytes)
    crypt.put_PaddingScheme(3);

    //  EncodingMode specifies the encoding of the output for
    //  encryption, and the input for decryption.
    //  It may be "hex", "url", "base64", or "quoted-printable".
    crypt.put_EncodingMode("hex");

    //  The blowfish algorithm uses a 64-bit block size,
    //  therefore the IV must be 8 bytes:
    const char * ivAscii;
    ivAscii = "12345678";
    crypt.SetEncodedIV(ivAscii,"ascii");

    //  For 256-bit encryption, the key is 32 bytes:
