RSA encryption

[Sigmahokies]

Hello everyone,

I'm trying to create a RSA encryption, but seem it is not function correctly.

Is Javascript know RSA? like, let rsa = new RSA(); do I have to download from github? 

here my code:

	                    let rsa = new RSA();
                    let prime = ["2", "3", "5", "7", "11", "13"]  //<-- Prime number
                    let random = prime[Math.floor(Math.random() * prime.length)];
                    let text = document.getElementById("readed");
                    document.getElementById("en").innerHTML = rsa.encrypt(random, text);
	

Seem  console log show it is not function.

RSA is not a native Javascript object, you will have to find a library. Wherever you found that code should have some documentation telling you where to get the library.

So, do I have to find source, then download it, then put in path to connect to this script?

You will need to include a script file on your page to use it, but you might not need to host it on your own server if they are offering a CDN.
