Everything can be cracked with computers, so if someone really wanted and knew what he does, he can figure anything out no matter what you do.
You could do your own compressor that works somehow significantly differently than most popular compression algorithms, but is it really worth the value? Probably not.
However, you can count it as unlikely for someone to crack the executable in the first place.
Highly unlikely, unless they have a very good decompiler... and I haven't heard about any that are consistently reliable. Heard about some that get lucky, but nothing steady.
Everything is crackable yea.. but the whole point is to make it harder for them.. :D
For example UPX is nice but you can uncrompress the exe with a simple command..
im just looking for something that hasnt got this function.. un-compressable..
There's ASPack. But I think that can be decompressed as well.
They also have ASProtect which I think encrypts the EXE or something...but I have no experience with that.
Why are you trying to compress the EXE? It's usually done to decrease file size.
Not just to decrease size, but to stop people editing with your strings, bitmaps.. etc..Quote:

having done a little search it seems like there is a decryptor for most compression tools.
upx is real good but y do they have the -d for..??? damn.
No matter what you do to compress a program, it's not adequate protection against internal data being extractable. I've a program that you can load an EXE into and it'll step through the code as it runs and show you what the program does at every step...most of it *is* machine code stuff but if you understand the basics of machine language (surprisingly, probably most surprisingly to RhinoBull, I actually do :-)) it's a wealth of information and even has form data in there too :-)
Nothing's safe any more :-P
(Edit: Program's called Numega Smartcheck)

In order to run, the file has to be decompressed into memory, so the decompression code is part of the .exe file, so it can always be extracted and analyzed, or a program can be written to run the extraction part, then save the extracted code from memory to another file..Quote:
