It wasn't my intention to claim about b4x.
I just wanted to point out that security is very important in IoT world, especially when it comes to controllig stuff.
I'm using b4x (b4a, b4j) for quite a long time - i write my whole house automation system in my free time (hobby),
thats why i'm very happy that b4x is evolving to IoT world, with lots of hardware support and code examples.
Last month I presented the idea of my system and what i made so far, to the company that installs alarm and home automation systems.
And the first question was, how secure is the connection between client (android b4a) and server (raspberrypi b4j).
At first the communication protocol i used in my system was websockets, now i'm trying to rewrite it to mqtt, and split the server into some separate components.
In fact i missed the b4j server feature to support https connections, because i don't use it in my solution.
I did some test on the metioned SecureWebSocket library:
https://www.b4x.com/android/forum/threads/securewebsocket-client-library.45981/#content
but i had some problems with it mentioned in the linked thread, so i decided to keep using standard b4a websocket lib for the time of beta tests.
Now, with the power of b4x and it's mqtt support i decided to rewrite all communication stuff to thie protocol.
After some tests i decided to switch to ssl communication.
In fact my knowledge of all this cetification stuff is very poor, that's why i asked for some examples.
