Crack the code and Win $5

Hello you people! I've just finished writing my fourth encryption tool, called 4CRYPT, the successor to the Enigma, D3N0V0crypt and 3NCRYPT0R. It's written in JAVA and probably the most advanced one of the four. Unlike the first three (Enigma has very limited and basic numeric key support, the first two didn't have any.) 4CRYPT has support for any ASCII based key of arbitrary length. It does encryption on a binary level, I can't tell you more or it will not be fun. (Hint: I didn't use native bit shifts, but I created my own shifting functions.)

Well good luck! Email me at hochanhong at yahoo dot com dot sg with your answer. If it's correct, you get $5 SGD, payable through either cash (if you're from singapore and I know you) or PayPal (this challenge is open globally).

You must get the original message by decrypting this. The key used here is "cheesesticks".

(Line breaks do not matter, it is a continuous string.)

To help you, here is some text encrypted with the same algorithms.

The plaintext is:

The quick brown fox jumps over the lazy dog

and the key used is "apple".
And encrypting will get you the string:

Good luck! First person will get the prize!
