zkpop-go

zkpop-go is a Go wrapper around the libzkpop library from the KEM-NIZKPoP project. It provides functions to generate keypairs, create Zero-Knowledge Proofs of Possession (ZKPoP), and verify proofs.

Getting Started

Prerequisites

Ensure you have the following installed on your system:

• GCC with AVX2, AES, and BMI2 support.
• OpenSSL development libraries:

  sudo apt install libssl-dev

• Go programming language (version 1.15+ recommended).
• CMake for building the external library.

Clone the Repository

First, clone the zkpop-go repository:

git clone --recurse-submodules https://github.com/gabrielzschmitz/zkpop-go.git
cd zkpop-go

If you have already cloned the repository without submodules, you can initialize and update them using:

git submodule update --init --recursive

Build the External Library

The Go wrapper depends on the libzkpop.a static library, which needs to be built from the KEM-NIZKPoP project.

To build the library:

1. Navigate to the project root directory:

   cd zkpop-go

2. Run the following commands to create the build directory, configure the build, and compile the library:

   mkdir build
   cd build
   cmake ..
   make

This will generate libzkpop.a inside build/lib/.

Build the Go Project

Once the library is built, you can compile the Go project and link it to the required libraries (OpenSSL and libzkpop.a):

CGO_CFLAGS="-mavx2 -maes -mbmi2 -O3 -I/usr/include/openssl" \
CGO_LDFLAGS="-L/usr/lib/x86_64-linux-gnu -lssl -lcrypto" \
go build -o zkpop

Run the Test

After building, you can run the main test file (main.go) to verify the implementation:

./zkpop

Notes

• Ensure you have the appropriate AVX2, AES, and BMI2 support on your system’s CPU.
• Modify the OpenSSL paths in CGO_CFLAGS and CGO_LDFLAGS if your installation differs.
• The compilation still not fully complete and need further investigation to include all necessary dependencies!
