modifying executables

[whiteGloveReview]

So i downloaded an executable and it's asking for a CD key (which I don't have) I know there's programs that can edit bytecodes and even translate the executable into something readable, could it be possible to take a program (like cheat engine) and use this to modify my input so that the program will accept it as valid regardless of what i put in

Sure, but it depends on how deep the rabbit hole goes. Does the program connect to the internet to authenticate the key? Is the CD key used for checksum calculations to verify the game hasn't been  tampered with? Or on that note, are there anti-tamper functions to make sure you can't modify it that easily? In other words, in theory you could do it, but it's probably not worthwhile. Unless you're really desperate or want that sweet "street cred"

 

Also while it's true that there are ways to turn programs into something "readable", that something "readable" is only going to stop at assembly. Even then, it's going to be the optimized version of the program (maybe) which would make it even more "fun" to read.

Best your going to get for readable is assembly. If your absolutely determined use ollydbg.
