Password Hashing and Verification Functions

This code defines four functions for password hashing, verification, salt generation, and password verification. The `hash_password` function is used to generate a hash of a password, `check_password` is used to verify the user's input password, `generate_salt` generates a new salt, and `verify_password` verifies the password.

    return hashed

def check_password(hashed_password, user_password):

    # Generate a new salt.
    return bcrypt.gensalt()

def verify_password(hashed_password, user_password):
    # Verify a password against a stored hash and return a boolean.
    return bcrypt.verify(user_password.encode('utf-8'), hashed_password)
