Quart-Bcrypt

Quart-Bcrypt is a Quart extension that provides bcrypt hashing utilities for your application. Orginal code from Flash-Bcrypt, which can be found at https://github.com/maxcountryman/flask-bcrypt

Due to the recent increased prevelance of powerful hardware, such as modern GPUs, hashes have become increasingly easy to crack. A proactive solution to this is to use a hash that was designed to be "de-optimized". Bcrypt is such a hashing facility; unlike hashing algorithms such as MD5 and SHA1, which are optimized for speed, bcrypt is intentionally structured to be slow.

For sensitive data that must be protected, such as passwords, bcrypt is an advisable choice.

Installation

Install the extension with the following command:

$ pip3 install quart-bcrypt

Usage

To use the extension simply import the class wrapper and pass the Quart app object back to here. Do so like this:

from quart import Quart
from quart_bcrypt import Bcrypt

app = Quart(__name__)
bcrypt = Bcrypt(app)

Two primary hashing methods are now exposed by way of the bcrypt object. Note that you need to use decode('utf-8') on generate_password_hash().

pw_hash = bcrypt.generate_password_hash('hunter2').decode('utf-8')
bcrypt.check_password_hash(pw_hash, 'hunter2') # returns True
