Bitmap to Dpf

[Kingdom Ablaze]

i really have no idea where to put this, but this sounded like the best place since it was made with rpg maker. anyways here is what i need i was wondering if anyone could download this File and tell me if they can get it back into any image format, i started with a bitmap obviously.

for those who are gonna ask why, its because im looking for another way to protect images, and so far making the game use my own image format has been working.(as long as no one can put it back together) so that way if anyone decrypts my game they wont get anything. (yes i know they can get the script and reverse engineer the way i made the files, then put them back together, but thats extra work on their part yes? and scripting knowledge which most people dont have)


sorry if this is the wrong place

So, you encrypted a file in a random way and now we shall try to decrypt it without any hint?
That's like trying to crack AES-256.

fair enough. i didnt use an encryption algorithm(yet) i used rubys marshal, im sure you can solve it, i know this is a all around is a bad idea, i just wanted to see how much it would slow some one down.

edit: im working on rewriting my data structure because as you may have noticed my file is 15 times bigger then the original(since my project has few resources i dont really mind) compression is not something ive tried to do before. so please bare with me on size, i just wanted to know if anyone could put the file back together.

plan of attack: see if it can be put back together, work on compression, then encryption.

The key to protecting your files is not hiding the way you encrypt them, but instead to encrypt them with something so strong that you can tell everyone exactly how you encrypted it, and they still can't decrypt it.

Of course, no matter how strong your encryption is, you still have to find a way to protect the encryption key.

i was gonna use: AES-Twofish-Serpent with a Whirlpool Hash. do you think 512 would bee too much? as for the key i could use thier Microsoft software id for windows(to feed my hash), since i write my own installers it wouldnt be hard to make it per computer based key. so each computer has a seprate key it was encrypted with.

edit: on the same note, can you read registrys with ruby? because now that i think of it i kinda need to be able to in able to read product id in vista/windows 7
