# RSA
[](https://crates.io/crates/rsa) [](https://docs.rs/rsa) [](https://travis-ci.org/RustCrypto/RSA) [](https://deps.rs/repo/github/RustCrypto/RSA)
A portable RSA implementation in pure Rust.
:warning: **WARNING:** This library has __not__ been audited, so please do not use for production code.
## Example
```rust
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) :construction:.
There will be three phases before `1.0` :ship: can be released.
1. :construction: Make it work
- [x] Prime generation :white_check_mark:
- [x] Key generation :white_check_mark:
- [x] PKCS1v1.5: Encryption & Decryption :white_check_mark:
- [x] PKCS1v1.5: Sign & Verify :white_check_mark:
- [ ] PKCS1v1.5 (session key): Encryption & Decryption
- [ ] OAEP: Encryption & Decryption
- [ ] PSS: Sign & Verify
- [x] Key import & export
2. :rocket: Make it fast
- [x] Benchmarks :white_check_mark:
- [ ] compare to other implementations :construction:
- [ ] optimize :construction:
3. :lock: Make it secure
- [ ] Fuzz testing
- [ ] Security Audits
