OpenPGP implemented in pure Rust, permissively licensed

rPGP is the only pure Rust implementation of OpenPGP, following the main RFCs

See for more details on the implemented PGP features.

It 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.


> cargo add pgp

Load a key and verify a message

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

let key_file = "key.sec.asc";
let msg_file = "msg.asc";

let key_string = fs::read_to_string("key.sec.asc").unwrap(),
let (secret_key, _headers) = SignedSecretKey::from_string(&key_string).unwrap();
let public_key = skey.public_key();

let msg_string = fs::read_to_string("msg.asc").unwrap();
let (msg, _headres) = Message::from_string(msg_string).unwrap();

// Verify this message

let msg_content = msg.get_content().unwrap(); // actual message content
