A portable RSA implementation in pure Rust.
## Example
```rust
use rsa::{Pkcs1v15Encrypt, RsaPrivateKey, RsaPublicKey};
let mut rng = rand::thread_rng();
let bits = 2048;
let priv_key = RsaPrivateKey::new(&mut rng, bits).expect("failed to generate a key");
let pub_key = RsaPublicKey::from(&priv_key);
// Encrypt
let data = b"hello world";
let enc_data = pub_key.encrypt(&mut rng, Pkcs1v15Encrypt, &data[..]).expect("failed to encrypt");
assert_ne!(&data[..], &enc_data[..]);
// Decrypt
let dec_data = priv_key.decrypt(Pkcs1v15Encrypt, &enc_data).expect("failed to decrypt");
assert_eq!(&data[..], &dec_data[..]);
```
> **Note:** If you encounter unusually slow key generation time while using `RsaPrivateKey::new` you can try to compile in release mode or add the following to your `Cargo.toml`. Key generation is much faster when building with higher optimization levels, but this will increase the compile time a bit.
> ```toml
> [profile.debug]
> opt-level = 3
> ```
> If you don't want to turn on optimizations for all dependencies,
> you can only optimize the `num-bigint-dig` dependency. This should
> give most of the speedups.
> ```toml
> [profile.dev.package.num-bigint-dig]
> opt-level = 3
> ```
## Status
Currently at Phase 1 (v) 🚧
There will be three phases before `1.0` 🚢 can be released.
1. 🚧 Make it work
- [x] Prime generation ✅
- [x] Key generation ✅
- [x] PKCS1v1.5: Encryption & Decryption ✅
- [x] PKCS1v1.5: Sign & Verify ✅
- [ ] PKCS1v1.5 (session key): Encryption & Decryption
- [x] OAEP: Encryption & Decryption
- [x] PSS: Sign & Verify
- [x] Key import & export
2. 🚀 Make it fast
- [x] Benchmarks ✅
- [ ] compare to other implementations 🚧
- [ ] optimize 🚧
3. 🔐 Make it secure
- [ ] Fuzz testing
- [ ] Security Audits
## ⚠️Security Warning
This crate has received one [security audit by Include Security][audit], with
only one minor finding which has since been addressed.
See the [open security issues] on our issue tracker for other known problems.
~~Notably the implementation of [modular exponentiation is not constant time],
but timing variability is masked using [random blinding], a commonly used
technique.~~ This crate is vulnerable to the [Marvin Attack] which could enable
private key recovery by a network attacker (see [RUSTSEC-2023-0071]).
You can follow our work on mitigating this issue in [#390].
## Minimum Supported Rust Version (MSRV)
This crate supports Rust 1.72 or higher.
In the future MSRV can be changed, but it will be done with a minor version bump.
