RSA-OAEP-PSS

A pure Rust implementation of the RSA public key cryptosystem.

The following features are available:

• Encryption using Optimal Asymmetric Encryption Padding (OAEP)
• Signature using Probabilistic Signature Scheme (PSS)

:warning: This crate has not been audited by any peer: We encourage you to review the code carefully before using it.

Installation

Add the following line to your Cargo.toml dependencies:

toml [dependencies] rsa-oaep-pss = "<version>"

Check the crates.io page to check out what is the current version.

How to use ?

Keys generation

rust let (public_key, private_key) = rsa_oaep_pss::generate_rsa_keys(&mut rng, 2048) .expect("keys generation error");

Encryption using OAEP scheme

```rust let message = b"some secret";

let mut oaep = rsaoaeppss::RsaOaep::new(rand::rngs::OsRng, &sha2::Sha256::new());

let ciphertext = oaep .encrypt(&public_key, message) .expect("encryption error");

let recovered = oaep .decrypt(&private_key, &ciphertext) .expect("decryption error");

assert_eq!(recovered, message); ```

Signature using PSS scheme

```rust let message = b"message to sign";

let mut pss = rsaoaeppss::RsaPss::new(rand::rngs::OsRng, &sha2::Sha256::new());

let signature = pss.sign(&private_key, message).expect("signature error");

let verification = pss.verify(&public_key, message, &signature);

assert!(verification.is_ok()); ```
