OK, this is for anyone who needs to manually generate a Django password. I was faced with this problem because I needed to manually insert a new Django user in the database. So, how to take the desired plain text password and to convert it properly so that you can insert it in the “password” field of the auth_user table in the Django database?
To answer this question, I had to take a look at the way Django handles user passwords. Basically, I needed to look at the following Python files from Django repository: utils.py, utils/encoding.py, utils/functional.py.
I’ve grabbed just the functions that I needed and put them together in the following piece of code that you can use.
Just set the “raw_password” variable to the password you want to use. The code uses sha1 as the encryption algorithm. I suppose that it will work for md5 too. Just set the “algorithm” variable to “md5”.
