class airflow.models.crypto.NullFernet[source]

A “Null” encryptor class that doesn’t encrypt or decrypt but that presents a similar interface to Fernet.

is_encrypted = False[source]
decrypt(self, b)[source]

Decrypt with Fernet.

encrypt(self, b)[source]

Encrypt with Fernet.

This function could fail either because Cryptography is not installed or because the Fernet key is invalid.
