The short answer is yes but here is some more context. So you want to make a web app for the results. You have a java app which is native windows.

As @SEJPM notes in the comments, the well-known Bouncy Castle library has an implementation of ElGamal asymmetric encryption. Here are some examples of how to use it. I've successfully used Bouncy Castle in a few projects so far, but not this particular type of encryption, so I can't comment on the specific reliability of this component.

Maybe just try watching a YouTube video on Python Tkinter or another Python GUI package. JavaScript is browser based and node.js is server-side JavaScript so they won't work. You could also use Java or .net, both have much more developed and mature offerings for Desktop apps over Python. There's a steeper learning curve with Java/.net than Python to get ...

Your best bet is probably to use tools which simulate keystrokes and mouse clicks, so that your script is indistinguishable from human physical input. Usually, such a tool also needs "visual recognition" to handle certain situations that arise. I'm not talking about CAPTCHA, which is still too difficult for any automation tools I'm aware of. The point is ...
