🦀 udpsec
Secure UDP implementation in Rust
Example
Client
use udpsec::Socket;
use std::io::Write;
use std::net::SocketAddr;
fn input(prefix: &str) -> String {
let mut input = String::new();
print!("{}", prefix);
std::io::stdout().flush();
std::io::stdin().read_line(&mut input);
input.trim().to_string()
}
fn main() {
let local_addr = input("Local addr: ").parse::<SocketAddr>().unwrap();
let remote_addr = input("Remote addr: ").parse::<SocketAddr>().unwrap();
let mut socket = Socket::new(local_addr).unwrap();
// Send shared secret generation request
let mut awaiter = socket.generate_secret(remote_addr).unwrap();
// Wait until it'll not be generated
while let None = socket.shared_secret(remote_addr) {
socket.recv();
}
// wait because sometimes result can return None
println!("Ping: {} ms", awaiter.wait(None).unwrap().as_millis());
// Input and send text
loop {
socket.send(remote_addr, input("> ").as_bytes().to_vec());
}
}
Server
use udpsec::Socket;
use std::io::Write;
use std::net::SocketAddr;
fn input(prefix: &str) -> String {
let mut input = String::new();
print!("{}", prefix);
std::io::stdout().flush();
std::io::stdin().read_line(&mut input);
input.trim().to_string()
}
fn main() {
let local_addr = input("Local addr: ").parse::<SocketAddr>().unwrap();
let mut socket = Socket::new(local_addr).unwrap();
loop {
if let Some((from, data)) = socket.recv() {
println!("[{}] {}", from, String::from_utf8(data).unwrap());
}
}
}
Custom data encoder/decoder
let mut socket = Socket::new(local_addr).unwrap();
socket.set_encoder(|data, key| {
// somehow encode data
data
});
socket.set_decoder(|data, key| {
// somehow decode data
data
});
