How to sign data on the client and verify it on the server?

Question

JavaScript

So I tested it, created a form with inputs, collected data from there and generated a cryptopro EDS
(base64 data + signature) through the browser plugin,
and then what to do with this data? send them to the server, and what should the server do?

Answer 1

Using the same algorithm, generate a signature (hash) for the same data and verify.
