rPGP


OpenPGP implemented in pure Rust, permissively licensed

rPGP is a pure Rust implementation of OpenPGP, following the main RFC

Also see the historical RFCs

See IMPL_STATUS.md for more details on the implemented PGP features.

rPGP offers a flexible low-level API and gives users the ability to build higher level PGP tooling in the most compatible way possible. Additionally, it fully supports all functionality required by the Autocrypt 1.1 e-mail encryption specification.

Usage

> cargo add pgp

Load a public key and verify an inline-signed message

use std::fs;
use pgp::{SignedPublicKey, Message, Deserializable};

let pub_key_file = "key.asc";
let msg_file = "msg.asc";

let key_string = fs::read_to_string(pub_key_file).unwrap();
let (public_key, _headers_public) = SignedPublicKey::from_string(&key_string).unwrap();

let msg_string = fs::read_to_string(msg_file).unwrap();
let (msg, _headers_msg) = Message::from_string(&msg_string).unwrap();

// Verify this message
// NOTE: This assumes that the primary serves as the signing key, which is not always the case!
msg.verify(&public_key).unwrap();

let msg_content = msg.get_content().unwrap(); // actual message content
let msg_string = String::from_utf8(msg_content.unwrap()).expect("expect UTF8");
println!("Signed message: {:?}", msg_string);

Generate and verify a detached signature with an OpenPGP keypair

use std::fs;
use pgp::{Deserializable, SignedPublicKey, SignedSecretKey};
use pgp::types::{PublicKeyTrait, SecretKeyTrait};
use pgp::crypto::hash::HashAlgorithm;

let priv_key_file = "key.sec.asc";
let pub_key_file = "key.asc";

let data = b"Hello world!";

// Create a new signature using the private key
let secret_key_string = fs::read_to_string(priv_key_file).expect("Failed to load secret key");
let signed_secret_key = SignedSecretKey::from_string(&secret_key_string).unwrap().0;

let new_signature = signed_secret_key.create_signature(|| "".to_string(), HashAlgorithm::default(), &data[..]).unwrap();

// Verify the signature using the public key
let key_string = fs::read_to_string(pub_key_file).expect("Failed to load public key");
let public_key = SignedPublicKey::from_string(&key_string).unwrap().0;

public_key.verify_signature(HashAlgorithm::default(), &data[..], &new_signature).unwrap();
