How does Django's csrf token encode?

Question

Django

If there is a django backend, then the first time you visit any page, django generates a csrf token in the cookie. It is not clear to me how this token is generated and on the basis of what.
My thoughts:
there is a SECRET_KEY value in settings.py. On first contact between django and the browser, django encodes this SECRET_KEY using an md5 encryption algorithm. I tried to encode SECRET_KEY with several popular algorithms (there are many online services like sha1-online.com on the Internet), but I did not get a value equal to the csrf token that is stored in my cookies Please help me
understand on the basis of what the csrf token is encoded and how exactly algorithm
