The format of the string returned includes the method that was used so that :func:`check_password_hash` can check the hash. The format for the hashed string looks like this:: method$salt$hash This method can **not** generate unsalted passwords but it is possible to set param method='plain' in order to enforce plaintext passwords. If a salt is used, hmac is used internally to salt the password. If PBKDF2 is wanted it can be enabled by setting the method to ``pbkdf2:method:iterations`` where iterations is optional:: pbkdf2:sha256:80000$salt$hash pbkdf2:sha256$salt$hash :param password: the password to hash. :param method: the hash method to use (one that hashlib supports). Can optionally be in the format ``pbkdf2:method:iterations`` to enable PBKDF2. :param salt_length: the length of the salt in letters. r7 r* �$)r4 rD )r6 r5 rG r �hZ actual_methodr r r �generate_password_hash� s rJ )�pwhashr6 r c C s< | � d�dk rdS | �dd�\}}}t�t|||�d |�S )a� Check a password against a given salted and hashed password value.
