RSA

A portable RSA implementation in pure Rust.

⚠️ WARNING: This library has not been audited, so please do not use for production code.

Example

extern crate rsa;
extern crate rand;

use rsa::{PublicKey, RSAPrivateKey, PaddingScheme};
use rand::rngs::OsRng;

let mut rng = OsRng::new().expect("no secure randomness available");
let bits = 2048;
let key = RSAPrivateKey::new(&mut rng, bits).expect("failed to generate a key");

// Encrypt
let data = b"hello world";
let enc_data = key.encrypt(&mut rng, PaddingScheme::PKCS1v15, &data[..]).expect("failed to encrypt");
assert_ne!(&data[..], &enc_data[..]);

// Decrypt
let dec_data = key.decrypt(PaddingScheme::PKCS1v15, &enc_data).expect("failed to decrypt");
assert_eq!(&data[..], &dec_data[..]);

Status

Currently at Phase 1 (v) 🚧.

There will be three phases before 1.0 🚢 can be released.

1. 🚧 Make it work
   • Prime generation ✅
   • Key generation ✅
   • PKCS1v1.5: Encryption & Decryption ✅
   • PKCS1v1.5: Sign & Verify ✅
   • PKCS1v1.5 (session key): Encryption & Decryption
   • OAEP: Encryption & Decryption
   • PSS: Sign & Verify
   • Key import & export
2. 🚀 Make it fast
   • Benchmarks ✅
   • compare to other implementations 🚧
   • optimize 🚧
3. 🔒 Make it secure
   • Fuzz testing
   • Security Audits
