llvm-obfuscator
LLVM trasnsformation passes for code obfuscation. Details described in paper
How To Build
OS X
Install LLVM via homebrew
brew install llvm@15
Set the directory in the CMakeLists.txt to the path of the installation of LLVM.
set(LT_LLVM_INSTALL_DIR "/opt/homebrew/opt/llvm@15")
$ cmake .
$ make
The libraries should now be present in the lib
folder of the project
Ubuntu
Install LLVM-15 via apt
sudo apt install llvm-15
Set the installation directory for LLVM in the CMakeLists.txt
set(LT_LLVM_INSTALL_DIR "/usr/lib/llvm-15")
In the root directory compile the project
cmake .
make
The libraries should now be present in the lib
folder of the project
Use
The libraries can be used with the opt
tool that comes installed with LLVM. Examples of using the transformation passes can be seen in the input
directory where each example has a compile.sh
that uses that specific transformation, or also in the demo
folder.
update the env-vars
(for example in the case of the ubuntu installation above)
#!/bin/bash
export llvm_path="/usr/lib/llvm-15"
export llvm_interpreter="/usr/lib/llvm-15/bin/lli"
export llvm_linker="/usr/lib/llvm-15/bin/llc"
How to run examples
After you set the env variables, which are used in the compile.sh
to the correct path, you should be able to execute the compile.sh
scripts in the provided examples of the demo
and input
folders
your setup.
source ./env-vars
cd ./demo
./compile.sh
