Hello! Is it possible to create a lightweight cipher node, for example, a present cipher or a speck cipher in node-red for payload protection?

[image] sreelakshmi25996: everyone can easily convert the code back from base64 You can use user/pwd authentication in mqtt and only allow the users you want to access the private topics.

[image] sreelakshmi25996: I am planning to create one but I just have a rough idea about the present cipher I need to code it in javascript and need to Create a new node using the instructions here [image] sreelakshmi25996: and need to create a HTML program for the same What does that…

I mean about the HTML file which defines the node's properties, edit dialog and help text

If you have protected it so only permitted users can access the data then why do you need to encrypt it?

If your payloads are small and you are looking for an out of the box solution you could use a json web token encrypt payload on way in and on the way back out.

But the data transfer is through wifi so if a person using a network analyser tool like Wireshark can easily access the data.

Easy enough to try... node-red-contrib-jwt (node) - Node-RED node-red-contrib-auth (node) - Node-RED node-red-contrib-iiot-jwt (node) - Node-RED You could use the below subflow (inline) to tell you how long the operation takes... https://flows.nodered.org/flow/63f29373e826a9fd4943d679d43e725f

Is it possible to encrypt the data using JSON web token in real-time data transmission?.
