STProto (Secure Transport Protocol) is an End-to-End Encryption network protocol. Like OpenSSL, it's a Session Layer Protocol, it focuses on secure transport bitween server and client, and provides a universal API which is similar to socket.

STProto supports these symmatric ciphers.

• AES-128-GCM
• AES-256-GCM
• ChaCha20-Poly1305
• AES-128-CCM
• AES-256-CCM

With STProto, you can write a simple server and client like this.

server.rs:

use std::io::*;
use stproto::connection::*;

fn main() -> std::io::Result<()> {
    let mut server = STServer::bind("localhost", 5000)?;
    server.listen()?;
    let client = server.accept();
    let mut data = Vec::new();
    client.read_to_end(&mut data)?;
    println!("{:?}", data);
    Ok(())
}

client.rs:

use std::io::*;
use stproto::connection::*;

fn main() -> std::io::Result<()> {
    let mut client = STClient::connect("localhost", 5000)?;
    client.write_all(b"test")?;
    Ok(())
}

If it runs properly, you will get:

$ ./server
[116, 101, 115, 116]
