Password Management Functions

This code block includes four functions for password management: generating a salt, hashing a password, checking a password, and increasing password strength. The `hash_password` function generates a secure password hash, while the `check_password` function is used to verify passwords.

def generate_salt():

    # This function hashes a password using bcrypt.hashpw. If no salt is provided, it generates a new one.
    if salt is None:
        salt = generate_salt()
    return bcrypt.hashpw(password.encode('utf-8'), salt)

def check_password(password, hashed):
    # This function checks if a password matches a hashed password using bcrypt.checkpw
    return bcrypt.checkpw(password.encode('utf-8'), hashed)

def randomize_password_strength(password):
    # This function adds random characters to the password to increase its strength
    random_chars = os.urandom(5).decode('utf-8')
    return password + random_chars
