如何使用 Django 在本地机器上创建目录/文件？

Question

I'm working on a blockchain project where I'm implementing a wallet using Django. A user logs in and get's to generate an address. Now, I want to store the user's private key/public key pair in a file locally on the user's machine every time a user generates an address, and be able to read that file again in the next session (at the user's will). I'm doing this because the app itself is a supernode of the blockchain and all users are virtual nodes. All communication between users happen through the supernode, thus the wallet functionality isn't the core function of the app.

Everything is working perfectly except I can't find a way to create files locally on the client's machine. I've perused the Django documentation but I can't seem to find anything useful (maybe I'm not looking in the right place).

Is there a way I can achieve that?

Note: I'm trying as much as possible to avoid JavaScript, and I don't want users to download/upload files manually.

Saveing data/files on the clients machine is restricted but modern browser for good (security) reason. However there are Cookies ( https://www.w3schools.com/js/js_cookies.asp , https://docs.djangoproject.com/en/3.2/topics/http/sessions/ ) or html5 webstorage ( https://www.w3schools.com/html/html5_webstorage.asp ).
