| .. py:class:: FernetProtocol |
| |
| Bases: :class:`airflow.typing_compat.Protocol` |
| |
| This class is only used for TypeChecking (for IDEs, mypy, pylint, etc) |

| .. method:: decrypt(self, b) |
| |
| Decrypt with Fernet |
| |
| |
| |
| |
| .. method:: encrypt(self, b) |
| |
| Encrypt with Fernet |
| |
| |
| |
| |
| .. py:class:: NullFernet |
| |
| A "Null" encryptor class that doesn't encrypt or decrypt but that presents |
| a similar interface to Fernet. |
| |
| The purpose of this is to make the rest of the code not have to know the |
| difference, and to only display the message once, not 20 times when |
| `airflow db init` is ran. |
| |
| .. attribute:: is_encrypted |
| :annotation: = False |

| |
| |
| .. method:: decrypt(self, b) |
| |

| |
| |

| |
| .. method:: encrypt(self, b) |

| :annotation: :Optional[FernetProtocol] |
| |
| |
| |
| .. function:: get_fernet() |
| Deferred load of Fernet key. |
| |
| This function could fail either because Cryptography is not installed |
| or because the Fernet key is invalid. |
| |
| :return: Fernet object |
| :raises: airflow.exceptions.AirflowException if there's a problem trying to load Fernet |
