Flask-Hashing

Flask-Hashing is a Flask extension that provides an easy way to hash data and check a hash of a value against a given hash. Flask-Hashing uses hashlib to actually hash data.

This extension prevents the user from needing to worry about how to hash data. Instead, developers are provided a simple call to do any necessary hashing of data.

This extension is intended to be used in place of Flask-Bcrypt, if the user so desires. Not everyone may want to use bcrypt for their hashing needs, and this provides a way to handle that use case.

Installation

$ pip install flask-hashing

or if you don't have pip:

$ easy_install flask-hashing

Usage

from flask import Flask
from flask.ext.hashing import Hashing

app = Flask(__name__)
hashing = Hashing(app)

After creating an instance of Hashing, we can hash data and check hashes of data as follows:

h = hashing.hash_value('secretdata', salt='abcd')
if hashing.check_value(h, 'secretdata', salt='abcd'):
    # do some stuff because the hashes are equal

Tests

Run

$ python setup.py test

or

$ python test_hashing.py
