I'm looking for a windows software that I can use as Socket Server for testing my Client with these options:

  • Support SSL and TLS with certificate management
  • Simple User interface with I/O area where I put messages to send and view received messages

Any Ideas?

Assuming you mean a websocket server, I would recommend using Node-Red. This is a Node.JS based visual flow-based tool originally designed for IoT work. It fully supports websockets. As well as the standard version, there are even versions that will run just in a browser or run on the desktop using Electron.

Using Node-Red, you can easily set up nodes to send and receive over websockets.

HTTPS is relatively straight-forwards, follow the instructions on the Node-Red documentation site.
