Php :: Flash - Errors Decrypting Crypto Blowfish Data?

I'm kind of new to ActionScript 3 at the moment and been trying to use the as3crypto library to encrypt some data with the blowfish algorithm before submitting it to the server for processing. I know you can use https, but most browsers still display the outbound data making it very easy for a user to fake a request. That's why I want to let the user see the page request, but not be able to read the data without decrypting.

Unfortunately for me the deocumentation on the as3crypto library is pretty much non existent aside from comments in the code. I've set up the flash side of things with a couple static functions to "implement" the as3crypto blowfish encryption and they work fine for encrypting/decrypting within flash only. The problem comes when I try to use the key to decrypt in PHP using the mcrypt library. The output I get is not the original code and I've spent a couple days trying to figure out why to no avail.elow is the code and explanations. For purposes of this example, the key used was 'mykey' (without the quotes) and the encoded data was 'Hello World' (again without the quotes).

Flash code (as3crypto blowfish helper):
package lib.ef.crypto
{
