Password Mixin
Mixin that adds some useful methods to ORM objects
Compatible with Python 3.5 >= 3.9
Install
pip install password-mixin
Setup
first create your objects (or ORM model) and add a __hash_secret__ meta field. Assign your application's secret value to __hash_secret__.
from password_mixin import PasswordMixin
from sqlalchemy import Model # or Django , Flask-Sqlalchemy... etc.
class UserModel(OrmModel, PasswordMixin):
password = Column(String()) # you must have a `password`.
# Now create a meta field to define the secret used to create the salt, for example:
__hash_secret__ = "your-app-secret"
Usage
The password is saved as the following: "<hash_name>:<hash>"
Password Hashing
from password_mixin import PasswordAttributeError
try:
user = UserModel()
user.password = "wizard123"
user.hash_password() # password is now `sha256:7ac5cf88e8c9d262b49af168d9c30e47f2945cc9c207f20af0a39f09aa04595e`
# Now you can save your user to your db etc.
except PasswordAttributeError:
# handle no password attribute
Validating Passwords
from password_mixin import PasswordMatchError
try:
user.check_password("wizard111")
except PasswordMatchError:
# handle passwords don't match
Example with Flask & Flask-Sqlalchemy
class UserModel(db.Model, PasswordMixin):
__tablename__ = "users"
__hash_secret__ = "wizard123"
id = db.Column(db.Integer, primary_key=True)
email = db.Column(db.String(100), nullable=False)
password = db.Column(db.String(100), nullable=False)
def create_user(self):
self.hash_password()
db.session.add(self)
Now, with the above setup you can run the following
u = UserModel(email="[email protected]", password="wizard123")
u.create_user()
db.session.commit()
