Easy Tokio Rustls

This library provides convenient abstractions for creating simple TLS sockets with tokio-rustls.

Example client usage

```rust use anyhow::Result; use tokio::io::{AsyncReadExt, AsyncWriteExt};

use easytokiorustls::TlsClient;

const BUFFER_SIZE: usize = 8 * 1024; const REQUEST: &[u8] = b"GET / HTTP/1.1\r\nHost: suchprogramming.com\r\n\r\n";

[tokio::main]

async fn main() -> Result<()> { let client = TlsClient::new("suchprogramming.com", 443).await?; let mut connection = client.connect().await?;

connection.write_all(REQUEST).await?;
let mut buffer = [0; BUFFER_SIZE];
loop {
    let read_size = connection.read(&mut buffer).await?;
    if read_size == 0 {
        connection.shutdown().await?;
        return Ok(());
    }
    let html = std::str::from_utf8(&buffer[0..read_size]).unwrap();
    print!("{}", html);
    if html.contains("</html>") {
        connection.shutdown().await?;
        return Ok(());
    }
}

} ```

Example server usage

```rust use anyhow::Result; use std::str; use tokio::io::{AsyncReadExt, AsyncWriteExt};

use easytokiorustls::TlsServer;

const BUFFER_SIZE: usize = 8 * 1024; const RESPONSE: &[u8] = b"HTTP/1.1 200 OK\r\nServer: a very great server\r\n\r\n";

[tokio::main]

pub async fn main() -> Result<()> { let interface = "0.0.0.0"; let port = 8443; let certfile = "/home/ubuntu/fullchain.pem"; let keyfile = "/home/ubuntu/privkey-rsa.pem";

let server = TlsServer::new(interface, port, cert_file, key_file).await?;
let listener = server.listen().await?;
println!("Listening on {}:{}", interface, port);

// This is a simplified server, handling 1 connection at a time certainly isn't recommended
let (stream, addr) = listener.stream_accept().await?;
println!("Client connected from {}", addr);

let mut client = stream.tls_accept().await?;
println!("TLS connection accepted");

let mut buffer = [0; BUFFER_SIZE];
let read_size = client.read(&mut buffer).await?;
let request = str::from_utf8(&buffer[..read_size])?;
println!("Client sent:\n{}", request);

client.write_all(RESPONSE).await?;
client.flush().await?;
println!("Reply sent, shutting down...");

client.shutdown().await?;

Ok(())

} ```
