Flask-Bcrypt for Hashing 🔐💡

Welcome to our Flask-Bcrypt tutorial! Today, we'll dive into the world of password hashing using the popular Flask extension, Flask-Bcrypt. We'll learn why password hashing is crucial, and how Flask-Bcrypt makes it easy to secure our applications. Let's get started!

What is Password Hashing? 💡

Password hashing is a process that converts a user's password into a scrambled string of characters, which is then stored in the database instead of the original password. This helps protect user data in case of a breach, as the original password remains hidden.

Why Use Flask-Bcrypt? 🎯

Flask-Bcrypt is a Flask extension that provides a simple and secure way to hash passwords using the Bcrypt algorithm. Bcrypt is a modern password-hashing function that's designed to be secure and resistant to attacks. Let's see how to install and use Flask-Bcrypt in our Flask application.

Installing Flask-Bcrypt 📝

To install Flask-Bcrypt, run the following command in your terminal:

bash

pip install flask-bcrypt

Setting Up Flask-Bcrypt 💡

After installing Flask-Bcrypt, let's set it up in our Flask application:

python

from flask import Flask
from flask_bcrypt import Bcrypt

app = Flask(__name__)
bcrypt = Bcrypt(app)

Hashing a Password 🎯

To hash a password, we'll use the generate_password_hash() function. This function returns a salted hash of the given password. Salt is a random string added to the password before hashing to make the hashes unique.

python

# Generate a salted hash of the password
password = "password123"
hashed_password = bcrypt.generate_password_hash(password).decode('utf-8')

Checking a Password 💡

To check if a given password matches the stored hashed password, we'll use the check_password_hash() function.

python

# Check if the entered password matches the stored hash
entered_password = "password123"
is_password_correct = bcrypt.check_password_hash('hashed_password', entered_password)

Practice Time 🎯

Now, it's your turn to practice! Let's see if you understood the concepts we've covered.
