I had some spare time yesterday. So I decided to develop a file compression format of my own called "GAO". Turns out it doesn't compare to other compression formats such as ZIP, RAR, and 7z. However I am curious how well it works as far as encryption goes. So to test it, I have uploaded two files. I have done a single layer of encryption on a file, and I want to see if anyone is capable of cracking it. If you are, post a comment and let me know what you found. I'll give you this much -- the header is 8 bytes long.
If you have a hex editor and want to give it a try, go ahead and download the original and the encrypted files. I don't know how effective my encryption format is, but hopefully I'll stump people. The first one to figure it out fully and post a comment explaining the format by October 27 will get a chance to try the ProSonic engine.

LOL, the encrypted file begins with DG. I used to do that too when I developed new file formats. :)
(of course with my initials)
also: 218 31 = 8154
Your header has no secrets to me! :p
I'm too lazy to check the rest of the file anyway... I gave a try to the header because, as I said, I had to develop several file formats in the past and these are common tricks ;)
Well the header isn't what I'm really looking for. I should have clarified that in my post -- I want to see if anyone can crack the rest of it. The first 8 bytes don't matter to me.
... So why is it exactly that an engine designed to be edited by hobbyists needs this level of indecipherable encryption? I mean, let's be real here. You're not a pro untill you support being down to Earth.
And gosh, you're so sensitive! Its not like we don't know you know your way around the block when it comes to programming. If you want to go around touting your engine as the best thing to happen to the community ever, then you should be prepared to take some flak from the community you are marketing to. Its a simple fact of life buddy.
Still, don't get me wrong, we are all looking forward to this.
Damian, I know that you weren't looking for that, I was just kidding :p
and no, I don't seem to be able to read the rest of the file, nice work.
The only thing I could figure out was that the original file held 99% of the secrets (eg. it was the encryption program)
