RSA

A portable RSA implementation in pure Rust.

:warning: WARNING: This crate has been audited by a 3rd party, but a full blog post with the results and the updates made since the audit has not been officially released yet. See #60 for more information.

Example

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

let mut rng = OsRng; let bits = 2048; let privkey = RSAPrivateKey::new(&mut rng, bits).expect("failed to generate a key"); let pubkey = RSAPublicKey::from(&priv_key);

// Encrypt let data = b"hello world"; let encdata = pubkey.encrypt(&mut rng, PaddingScheme::newpkcs1v15(), &data[..]).expect("failed to encrypt"); assertne!(&data[..], &enc_data[..]);

// Decrypt let decdata = privkey.decrypt(PaddingScheme::newpkcs1v15(), &encdata).expect("failed to decrypt"); asserteq!(&data[..], &decdata[..]); ```

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 :whitecheckmark:
   • [x] Key generation :whitecheckmark:
   • [x] PKCS1v1.5: Encryption & Decryption :whitecheckmark:
   • [x] PKCS1v1.5: Sign & Verify :whitecheckmark:
   • [ ] PKCS1v1.5 (session key): Encryption & Decryption
   • [x] OAEP: Encryption & Decryption
   • [x] PSS: Sign & Verify
   • [x] Key import & export
2. :rocket: Make it fast
   • [x] Benchmarks :whitecheckmark:
   • [ ] compare to other implementations :construction:
   • [ ] optimize :construction:
3. :lock: Make it secure
   • [ ] Fuzz testing
   • [ ] Security Audits
