def generate_salt():
    # This function generates a new salt using bcrypt.gensalt() and returns it.
    return bcrypt.gensalt()

def hash_password(password, salt=None):
    # This function takes a password and an optional salt, hashes the password using bcrypt.hashpw(),
    # and returns the hashed password.
    if salt is None:

    return bcrypt.hashpw(password.encode('utf-8'), salt)

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

def get_random_bytes(length=16):
    # This function generates a random sequence of bytes using os.urandom() and returns it.
    return os.urandom(length)

def get_hashed_password(password):
    # This function generates a hashed password using the hash_password() function.
    return hash_password(password)

def verify_password(password, hashed_password):
    # This function verifies if the provided password matches the hashed password using the check_password() function.
    return check_password(password, hashed_password)
