🔔 *Keep in mind that the library is WIP and may contain some unpolished interfaces. If you encounter any issues or have any suggestions, feel free to ping us on our Discord server or open a new issue in the [GitHub repository](https://github.com/fairmath/openfhe-rs/tree/master).*

OpenFHE-rs is a Rust interface for the OpenFHE library, which is renowned for its comprehensive suite of Fully Homomorphic Encryption (FHE) schemes,
all implemented in C++.
By providing a Rust wrapper for OpenFHE, we aim to make these advanced FHE capabilities easily accessible to Rust developers.
Whether you're developing secure data processing applications or privacy-focused tools, OpenFHE-rs enables you to leverage the powerful encryption technologies of OpenFHE seamlessly within your Rust projects.
# Installation
To use OpenFHE-rs, you'll need to install several dependencies and follow the installation steps for both the core OpenFHE library and the Rust crate.
## Prerequisites
Ensure you have the following dependencies installed:
* `CMake >= 3.5.1`
* `G++ >= 11.4`
* `Rust >= 1.78`
* `Git`
## Installation process
### Core OpenFHE library installation
To build and install the OpenFHE library, follow the steps below or refer to [OpenFHE's installation documentation](https://openfhe-development.readthedocs.io/en/latest/sphinx_rsts/intro/installation/installation.html).
1. Clone the repository
```bash
git clone https://github.com/openfheorg/openfhe-development.git
cd openfhe-development
```
2. Configure CMake
```bash
cmake -B ./build -DBUILD_SHARED=ON .
```
3. Build and install the C++ OpenFHE library
```bash
make -C ./build -j$(nproc)
make -C ./build install
```
4. Update the cache for the linker
```bash
sudo ldconfig
```
## Configuring your project to use the crate
To use the OpenFHE crate in your Rust project, add it as a dependency from [crates.io](https://crates.io/crates/openfhe):
```bash
cargo add openfhe
```
You also need to add a small piece of code for the core dependencies' configuration in your `build.rs` file:
```rs
fn main
{
// linking openFHE
println!("cargo::rustc-link-arg=-L/usr/local/lib");
println!("cargo::rustc-link-arg=-lOPENFHEpke");
println!("cargo::rustc-link-arg=-lOPENFHEbinfhe");
println!("cargo::rustc-link-arg=-lOPENFHEcore");
// linking OpenMP
println!("cargo::rustc-link-arg=-fopenmp");
// necessary to avoid LD_LIBRARY_PATH
println!("cargo::rustc-link-arg=-Wl,-rpath=/usr/local/lib");
}
```
To build and run a complete working example, go to the [crate_usage](https://github.com/fairmath/openfhe-rs/tree/master/crate_usage) directory
(assuming that the OpenFHE library is already installed),
1. Build the application
```bash
cargo build
```
2. Run
```bash
cargo run
```
# Custom crate installation from the source
You can adjust the installation process by building the crate manually.
In that case, you need to clone the Fair Math's [openfhe-rs](https://github.com/fairmath/openfhe-rs) repo to your local machine and build it:
1. Clone the repository
```bash
git clone https://github.com/fairmath/openfhe-rs.git
cd openfhe-rs
```
2. Build the library
```bash
cargo build
```
3. Run tests
```bash
cargo test -- --test-threads=1
```
4. Run the examples
```bash
cargo run --example function_evaluation
cargo run --example polynomial_evaluation
cargo run --example simple_integers
cargo run --example simple_real_numbers
```
