What language will protect my source code?

Question

I wish to create shareware software that contains a registration algorithm. I am looking for a programming language, that cannot be easily decompiled into readable code. F

Answer 1

All code can be read back in assembly. Someone can reverse engineer your application and see what the machine is doing.

Answer 2

Repeat after me: "Obscurity is not security."

You would be better off using a hard encryption algorithm (where "hard" doesn't mean "difficult", but "not bi-directional; not easily reversible".

Answer 3

Try finding an obfuscator. As the name suggests it obfuscates the code enough that reverse-engineering it will not be trivial.

Or use C/C++. Those can be disassembled, but that's it.

Of course, this is just enough to keep the not-sufficiently-competents from understanding and reverse-engineering the code.

Answer 4

Isn't this logically impossible?

If you can run the code, you can get the instructions being executed by your CPU. At that point, your algorithm is readable, for some definitions of readable.

Answer 5

If you're lookig "for something that can be only decompiled into assembly", that essentially means that you want to use a language that gets compiled (or assembled) directly into a native code executable.

The usual prime suspects then are C, C++, Delphi, VB6. Of course, also assembly meets your criteria, although I doubt you'd want to write any project of decent size in it.

Answer 6

"I'm looking for something that can be only decompiled into assembly."

Try writing your program in assembly. That is the best possible solution.
