Need help breaking locked file

[_furinax_]

Hi Everyone,

Don't worry what the title says, I'm not asking for anything illegal to be done. I'm a programmer but I don't know much about crypto... even so I've recently came up with a method for encrypting files and now want to see how well my method would stand up to people who actually know what they're doing (very much unlike myself).

To prove I'm not just some skid whos stolen a locked archive or something, I'd provide both the original and encrypted version of the file. I basically want to see how easily someone could take my "encrypted" file and return it back into it's original, functional condition. I realize it's a tall order since it's a completely custom method but... let me know anyway. Thanks!

So, are you going to post the files?

Sorry about that, wanted to see if anyone was even interested first. You can get some sample files here:

I included originals and encrypted versions. I also included a mp3 and a txt file (the txt because it being human-readable, might make it easier to understand, if at all, the process). Again like I said I don't know a whole lot about this entire subject it's just that this idea makes sense in code, and getting an opinion from someone who does have knowledge would be invaluable. Thanks!

So, you basically scramble the order? BTW, this is a weak cryptosystem. Don't use it in the practical world.
