I made code for signing in users and storing data about them. Everything is fully encrypted and secure also, it is meant to be imported into other code. I'm looking for ways to improve it and to fix any bugs people might find.

import pickle

import base64



class user():

    def __init__(self, username, password, user_data):

        self.username = username

        self.password = password

        self.user_data = user_data



def get_user():

    try:

        user_saves = open("users", 'rb')

        users = dict(pickle.load(user_saves))

        user_saves.close

        name, password, users = sign_in(users)

    except:

        name, password, users = new_user(True)



    name = base64.b64decode(name.decode('utf-8'))

    password = base64.b64decode(password.decode('utf-8'))

    return name, password, users



def new_user(is_first = False, users=None):

    print('Creating account... ')

    if users != None:

        loop = True

        while loop:

            name = input('What is your username: ')

            name = base64.b64encode(name.encode('utf-8'))

            if name in users: 

                print('Already taken.') 

            else: 

                loop = False

                password = input('What is your password: ')

                password = base64.b64encode(password.encode('utf-8'))

    else:

        name = input('What is your username: ')

        name = base64.b64encode(name.encode('utf-8'))

        password = input('What is your password: ')

        password = base64.b64encode(password.encode('utf-8'))

    if is_first == True:

        user = {name:password}

        user_saves = open("users", 'wb')

        pickle.dump(user, user_saves)

        add_user_data('', password, True)

        return name, password, user

    else:

        add_user_data('', password)

        users.update({name:password})

        user_saves = open("users", 'wb')

        pickle.dump(users, user_saves)

        return name, password, users

    user_saves.close



def sign_in(users):

    nsi = True #not signed in

    while nsi == True:

        username = input('What is your username: ')

        username = base64.b64encode(username.encode('utf-8'))

        if username in users:

            password = input('What is your password: ')

            password = base64.b64encode(password.encode('utf-8'))

            if password == users.get(username):

                print('working')

                nsi = False

                return username, password

            return False

        else:

Security

Everything is fully encrypted and secure

Oh, really? I hope that you aren't confusing encoding with encryption. I don't see any encryption taking place.

This is a huge topic, so you have some reading to do - but the bar for 'secure password store' is significantly above where this program currently resides.

Class syntax

This:

class user():

should be

class User:

Also, you're currently using it as a struct with no methods. That should change - you should move some of your code to be methods on that class.

Break

This:

loop = True

while loop:

should be reworked. You can use a while True, and replace the loop = False with a break at the end of that if block.

File handles

Rather than explicitly closing your files, you should usually use them in a with block. Also, this:

user_saves.close

doesn't do what you think it does; in fact it does nothing. For the function call to occur, you need to add ().

Redundant else

This:

    return name, password, user

else:

doesn't need an else, because you've returned in the previous block.

Write a main method

...to pull this code out of global scope:

name, password, users = get_user()

data = get_user_data(password)

print(data)

user_stats = user(name, password, data)
