Just an implementation of [Paillier Cryptosystem](https://en.wikipedia.org/wiki/Paillier_cryptosystem) written in Rust.

## Build & Test

```bash
cargo build
cargo test
```

## Why

For research purpose. And the encryption of the Paillier algorithm supports the properties of homomorphic addition and scalar multiplication

## Production Ready?

No, Its only for educational & research purpose. The code has not undergone any security audit

## Usage

Please see unit tests in [`lib.rs`](./src/lib.rs)
