Async sockets.

[Velho]

Hello! Is it possible to run the SSL compatibility interface as asynchronous or non blocking? How is now.. Doesn't the SSL_accept returns WANT_READ and WANT_WRITE incase there is more to do. Would you have any tips? Does the examples support non blocking?

Hello!

TLSe is async by design. You should switch to tls APIs. The SSL_* APIs are just for basic libssl compatibility. Check tlsclienthello.c and tlshelloworld.c. libssl compatibility is basic at most.

@eduardsui Thanks for the response! I'll do as you suggested.

I have question about the tls_hellowrold.c. As I assume the tls_consume_stream(..) does the handshake from the recv(..) data? Afterwards using the tls_read(..) from the tlse implementation to read from the socket?

Thanks

It seems to work, I do a loop until the connection is established, but for some reason tlse writes the headers to the stream. Is there something I am doing wrong?

My bad, I had echo there somewhere in the async event handler 😬. Thanks for the support @eduardsui. Everything seems to be working as intended.

I am currently handling my writing as,

rc = tls_write (..)
if (rc  < 0)
  // error
else
  tls_close_notify(..)
  send_pending(..)

Is that correct?

[eduardsui]

Yes, perfect.
