When and how should I obfuscate my Delphi code?

Question

What should I know about code obfuscation in Delphi?

Should I or shouldn't I do it?

How it is done and is there any good tools (commercial/free) to automate it?

Answer 1

Why would you need to?

As a whole Delphi does not decompile back, unlike .net, so, while decompilation is always a bit of a risk, Ive never found a decompiler that actually did it to a useful way, lots of areas got left as assembler and so on.

If people want to rework your work, they can, no matter what, obfuscation or not, heck, some coders write almost naturally obfuscated code (having worked with a few)

My vote therefore, is shouldnt bother. Unless someone can show me a decompiler for delphi that really works, and produces full sets of compilable, and all delphi where it was originally, I wouldnt worry one drop.

Answer 2

Pythia is a program that can obfuscate binaries (not the source) created with Delphi or C++ Builder. Source code for Pythia is here.
