Client side encryption in Django. Encrypt files in client as well as server before storing

Question

A Beginner
I am building and Django project in which I am trying to store files on my heroku server. But I want to encrypt it before sending and then encrypt again at server before storing it. Decryption will be the same in reverse.
I need help finding right client side frameworks and some already built resources to the same for reference.
The file isn’t meant to be accessed by any third person as of now, so only working on AES encryption method. RSA encryption ideas are also welcomed for future updates.

Yeah I get that, can you share some resources.
