SHA256 of a string in the script is possible?

Hi @gemu2015

Is there anyway to use the functions SHA256 that is used inside the tasmota core, is the script?

Let me explain. I would like to send a unique key from the mqtt server to the device that will allow it to execute a function inside the script, and i would like this key to be hashed using devices variables that only i would know.

the server part is easy there is a lot of libraries to do so, but i could not found a way to do this in the script .

I suppose that there is always a possibility to send a ‘br’ command to embed Berry code and use Berry’s crypto library
