About OpenFHE-rs

☀️ OpenFHE-rs is a joint project by FairMath & OpenFHE

OpenFHE-rs is a Rust interface for the OpenFHE library. OpenFHE is known for its wide range of Fully Homomorphic Encryption (FHE) schemes, all implemented in C++. We're bringing this capability to Rust developers.

By offering a Rust wrapper for OpenFHE, we make it easier for Rust devs to use advanced FHE schemes in their projects. Whether you're building secure data processing apps or privacy-focused tools, OpenFHE-rs helps you do that with the power of OpenFHE's encryption technology.

Current status

The library is under development and the ETA of the first version is set to Q2 2024.

Installation from source

Install Dependencies

CMake >= 3.5.1
Clang >= 12.0 or GCC >= 11.4
Rust >= 1.78
Git

Unix

On Debian systems, everything can be installed with the following command:

Installation process

Build and install OpenFHE library. Right now you need to use the Fair Math fork. It contains required features, which will be included in the next planned release (v1.1.5):
1. Clone the repository

   git clone https://github.com/fairmath/openfhe.git
   cd openfhe

Configure CMake

   cmake -B ${OPENFHE_BUILD:-build} -DBUILD_EXAMPLES=ON -DBUILD_EXTRAS=ON -DBUILD_SHARED=ON .

Build and install the C++ OpenFHE library

   make -C ${OPENFHE_BUILD:-build} -j$(nproc)
   make -C ${OPENFHE_BUILD:-build} install

Make sure you have rustc with cargo installed first.
Clone the Fair Math openfhe-rs repo to your local machine and build:
1. Clone the repository
```
git clone https://github.com/fairmath/openfhe-rs.git
cd openfhe-rs
```
  1. Configure your dynamic linker bash sudo ldconfig
2. Build the library
```
cargo build
```
  1. Run tests bash cargo test -- --test-threads=1
3. Run the examples

   cargo run --example polynomial_evaluation
