Asymmetric message encryption?

Question

JavaScript

Good afternoon. Now I am doing a small project in which users communicate via WebRTC. You need to add encryption directly messages. I decided to use AES for encryption, and the Diffie-Hellman algorithm for key exchange, but a problem arose. If the user sets a private key that is too large (more than 3 digits), then js can no longer calculate it. Otherwise, the master key is too simple. What do you think is the best way to organize asymmetric encryption? I read about RSA, but, as I understand it, I will not be able to simultaneously generate private and public keys in the browser, and the project requires maximum simplicity for the user (i.e. without opening the terminal and generating keys through such terrible console commands). Thanks in advance.

Answer 1

If someone is relevant, I found an excellent CrypticoJS library . Everything is described in detail in the test.html file and is just right for my question.

Answer 2

I was not seriously interested in this issue, but I think you should pay attention to elliptic cryptography, somewhere I even saw open implementations in js.

Answer 3

Why asymmetric encryption if you generate a shared Diffie-Hellman key?
