rama-boring-tokio

An implementation of SSL streams for Tokio backed by BoringSSL in function of Rama.

Documentation

Usage

First, add this to your Cargo.toml:

cargo add rama-boring-tokio

Then, use either accept or connect as appropriate.

use rama_boring::ssl;
use tokio::net::TcpListener;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let listener = TcpListener::bind("127.0.0.1:8080").await?;
    let (tcp_stream, _addr) = listener.accept().await?;

    let server = ssl::SslMethod::tls_server();
    let mut ssl_builder = rama_boring::ssl::SslAcceptor::mozilla_modern(server)?;
    ssl_builder.set_default_verify_paths()?;
    ssl_builder.set_verify(ssl::SslVerifyMode::PEER);
    let acceptor = ssl_builder.build();
    let _ssl_stream = rama_boring_tokio::accept(&acceptor, tcp_stream).await?;
    Ok(())
}

This library is an implementation of TLS streams using BoringSSL for negotiating the connection. Each TLS stream implements the Read and Write traits to interact and interoperate with the rest of the futures I/O ecosystem. Client connections initiated from this crate verify hostnames automatically and by default.

rama-boring-tokio exports this ability through [accept] and [connect]. accept should be used by servers, and connect by clients. These augment the functionality provided by the [boring] crate, on which this crate is built. Configuration of TLS parameters is still primarily done through the [boring] crate.
