Websocket TLS session renegotiation

MicroEJ SDK
1

Hello,

I am using the WebSocketSecure class for a long-lived connection in our application on ESP32. Our TLS / SSL layer in C is managed by mbedTLS. I want to be able to perform a TLS session renegotiation on my WebSocketSecure, like the mbedtls_ssl_renegotiate function in C. How can I achieve that?

Best regards,

Hi @yoann

We do not have a way to trigger the renegotiation at application level, like the mbedtls_ssl_renegotiate at BSP level. However if the server is trying to renegotiate it will work. You could call the mbedtls_ssl_renegotiate though SNI: Simple Native Interface (SNI) — MicroEJ Documentation

Hello,

Thanks for your answer, we will check if we can trigger the renegotiation from our server.
