A DMP-mitigation ready, printf-modified fork of libSodium

About

libNa is derived directly from libSodium, with all printf(%s) statements systematically replaced by printf(%c).
This repository demonstrates secure build and deployment with Splitting Secret.

Build Instructions

To build libNa from source with DMP mitigation:

1. Clone and enter this repository:

   git clone https://github.com/dmp-mitigation/libNa.git
   cd libNa

2. Set required environment variables:

   • DMP_LLVM: Path to your DMP_LLVM build directory.
   • DMP_RT : Path to your DMP Runtime (DMP_RT) repository.

   echo $DMP_LLVM   # Should output the path to DMP_LLVM build directory
   echo $DMP_RT     # Should output the path to DMP_RT repository

3. Build with Clang and DMP options:

   env CC=$DMP_LLVM/bin/clang \
     CFLAGS="-lstdc++ -mavx2 -Dsecure=1 -mllvm -smalloc -mllvm -smalloc-mem -mllvm -enable-secure-spill -I$DMP_RT/include/ -L$DMP_RT/lib -lslibc -lsmalloc -lssyscall -Wl,--rpath,$DMP_RT/lib" \
     make
