Gateway Reencryption Computer

A Rust wrapper API for IronCore Labs' Recrypt library, providing a simplified interface for proxy re-encryption operations.

Overview

This project provides a high-level wrapper around the Recrypt library, making it easier to integrate proxy re-encryption capabilities into Rust applications. It's organized as a workspace with multiple members:

• compute: Core computer implementation (with gRPC server)
• recrypt: Vendored fork of the IronCore Labs Recrypt library

Prerequisites

• Rust 1.75 or later
• Cargo
• System dependencies required by Recrypt

Installation

Add this to your Cargo.toml:

[dependencies]
recrypt-compute = "0.1.0"

Usage

Basic example of encrypting and re-encrypting data:

use recrypt_wrapper::{RecryptApi, EncryptionKey};

fn main() -> Result<(), Box<dyn Error>> {
    // Keys for encryption benchmark
    let (priv_key1, pub_key1) = new_encryption_keypair();
    let signing_keys = new_signing_keypair();

    let encrypted = encrypt(&data, &pub_key1, &signing_keys).unwrap();

    // Transform the encryption to second delegatee
    let (priv_key2, pub_key2) = new_encryption_keypair();
    let transform_key = new_transform_key(&priv_key1, &pub_key2, &signing_keys);
    let transformed = transform(encrypted, transform_key, &signing_keys);

    let decrypted = decrypt(&transformed, &priv_key2, size).unwrap();

    Ok(())
}
