Actix-web Library / Middleware to encrypt REST / POST data

help
1

I use actix-web as REST API server on my project.
Client browser can send requests in JSON format to server and the actix-web server will reply in kind.

But I don't like strangers to sniff around the data being sent and received by the client. In production I don't want the data to be read easily using chrome developer tools (F12) or equivalents

In node.js I can implement a middleware to stringify the payload into JSON string, decrypt, and encrypt the payload with crypto (jquery - Javascript encryption for JSON object - Stack Overflow)

Is there any already available rust package that do payload encryption out-of-the-box or do I need to implement it myself ?

What I understand is that you don't want the web page to see the data after the response during debug. At present, tide, actix-web and hyper don't have encryption functions in this regard. They are just web frameworks, and you may need to use crates.io find JSON data encryption and implement it yourself.

However, I think you must have added serde crate. you can try serde-encrypt
