Asynchronous TLS/SSL streams for [Tokio](https://tokio.rs/) using
[Rustls](https://github.com/ctz/rustls).

### Basic Structure of a Client

```rust
use webpki::DNSNameRef;
use rustls::ClientConfig;
use tokio_rustls::ClientConfigExt;

// ...

let mut config = ClientConfig::new();
config.root_store.add_server_trust_anchors(&webpki_roots::TLS_SERVER_ROOTS);
let config = Arc::new(config);
let domain = DNSNameRef::try_from_ascii_str("www.rust-lang.org").unwrap();

TcpStream::connect(&addr)
	.and_then(|socket| config.connect_async(domain, socket))

// ...
```

### Client Example Program

See [examples/client.rs](examples/client.rs). You can run it with:

```sh
cargo run --example client hsts.badssl.com
```

Currently on Windows the example client reads from stdin and writes to stdout using
blocking I/O. Until this is fixed, do something this on Windows:

```sh
echo | cargo run --example client hsts.badssl.com
```

### Server Example Program

See [examples/server.rs](examples/server.rs). You can run it with:

```sh
cargo run --example server -- 127.0.0.1 --cert mycert.der --key mykey.der
```
