Dumb Obfuscator

The answer to "why shouldn't people put RSA computations everywhere in their programs?".

If you want to read the step-by-step tutorial you can read the post on my blog.

Setup

You should really read my blog post if you want this to work out of the box. Basically though, you just need to add LLVM's official apt repositories to your Ubuntu machine and install clang-9.

Anyway, you can pretty much change LLVM version by changing every reference to clang-9 to whatever clang you want to use. You need to change llvm-config-9 references too.

Building the Pass

Run ./build.sh.

This will basically create ./build/ and run cmake on it.

Testing the Pass

Run ./test.sh.

This will compile ./test/test.c into human-readable LLVM IR, run the pass on it, show the final IR and run the obfuscated program.
