Can anyone tell me how to deal with Websocket frame architecture or masking data as per WebSocket frame are concerned?

[SVerm.3]

Can anyone tell me any library for Websocket frame architechture in STM32cubeIDE. I have seen many links in Github but failed to implement so can anyone tell me the simplest method to do WebSocket frame for masking the Transmit data to Websocket Server.

There's an almost working lwIP patch for WebSocket server at https://savannah.nongnu.org/patch/?9525.

Its RFC is at https://datatracker.ietf.org/doc/html/rfc6455.
