Implement key size mismatch

[Sculas]

srt-rs version: commit 1236c22 I have my listener setup like this:

let (_listener, mut receiver) = SrtListener::builder()
    .encryption(KeySize::AES256.as_raw(), "mypass")
    .bind(port)
    .await?;
while let Some(request) = receiver.incoming().next().await {
    let socket = match request.accept(None).await {
        Ok(socket) => socket,
        Err(err) => {
            error!("SRT connection error: {}", err);
            println!("{err:?}");
            continue;
        }
    };
    // ...
}

If I then use ffplay to connect like this:

ffplay "srt://127.0.0.1:51379/?passphrase=wrongpass"

I get this in my console output:

thread 'tokio-runtime-worker' panicked at 'not implemented: Key size mismatch', C:\Users\lucas\.cargo\git\checkouts\srt-rs-5cd6a57c40b8e1b5\1236c22\srt-protocol\src\protocol\pending_connection\hsv5.rs:72:17
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
SRT connection error: oneshot canceled
Custom { kind: NotConnected, error: Canceled }

If I recall correctly, the server should tell the receiver its key size. Is this a bug or has that not been implemented yet? I know it says not implemented, but since "Encryption" has been marked as working in the README I thought I could use it.

Note: Setting the key size manually in ffplay does work (default 0):

ffplay "srt://127.0.0.1:51379/?passphrase=mypass&pbkeylen=32"

But if you then use an invalid password:

ffplay "srt://127.0.0.1:51379/?passphrase=wrongpass&pbkeylen=32"

You'll get this error in your console output:

SRT connection error: oneshot canceled
Custom { kind: NotConnected, error: Canceled }
