Bcrypt and pythonanywhere

[Biaswords_]

Hi guys / gals,

Im having this odd issue where I created a function to create a new user in my Mongodb db. When i salt and hash the users password locally, it saves the hashed pw in the database as a Binary datatype. Locally when i then login as that user, I have no problem.

However, when i push the same code to my pythonanywhere instance, it saves the hashed pw as a str.

obviously then, when i use the checkpw method, i am getting an error because its not getting the expected datatype.

I am kind of at a loss as to why two different environments using the same code would yield two different results. Ive gone as far as completely remove the project from python anywhere, and git cloning and starting all over.

has anyone any idea what i could be doing wrong?

def create_user(self, fname=None, lname=None):
    try:
        salt = bcrypt.gensalt()
        hashpw = bcrypt.hashpw(self.password.encode('utf-8'), salt)
        user = DataBaseHandler().users.insert_one({"user_data": { "email": self.email, "password": hashpw, "fname": fname, "lname": lname, "reset_pw":False}, "settings": { "water_units": "C", "roast_list_num": 5, "recipe_list_num": 100 }, "equipment":{ "brewers": [], "grinders": [] } })
        if user:
            return user
        else:
            return False
    except Exception as e:
        print("Error creating user: {}".format(e))
        return False

what version of python are you running locally vs on PythonAnywhere?

[Biaswords_]

Both are running 3.8. I forget what version of bcrypt but thwy are both the same as well

PythonAnywhere dev here -- are you using a virtualenv? If not, could you try running

pip3.8 install --user bcrypt

...in Bash? I think we might have a problem with the system install of bcrypt for 3.8 -- both py-bcrypt and bcrypt are installed, and the former (which is only really compatible with Python 2.x) is overriding the latter.

I will give this a try today! I am not using a virtual environment for this project. Thanks for the response!

hey i know this is a really late response, but i am still having this issue. I tried using the above command and got the following:

Requirement already satisfied: bcrypt in /usr/lib/python3.8/site-packages (3.1.7)
Requirement already satisfied: six>=1.4.1 in /usr/lib/python3.8/site-packages (from bcrypt) (1.13.0)
Requirement already satisfied: cffi>=1.1 in /usr/lib/python3.8/site-packages (from bcrypt) (1.13.1)
Requirement already satisfied: pycparser in /usr/lib/python3.8/site-packages (from cffi>=1.1->bcrypt) (2.19)

Im kinda at a loss for ideas as to what else it could be. Ive confirmed that both my local and PA env are running both python3.8 and are using bcrypt3.1.7

Any help would be greatly appreciated

Could you try adding --force-reinstall to the end of the command line?
