--- fixes: - | [`bug 1677308 `_] Removes ``pycrypto`` dependency as the library is unmaintained, and replaces it with the ``cryptography`` library. upgrade: - | [`bug 1677308 `_] There is no upgrade impact when switching from ``pycrypto`` to ``cryptography``. All data will be encrypted and decrypted using identical blocksize, padding, algorithm (AES) and mode (CBC). Data previously encrypted using ``pycrypto`` can be decrypted using both ``pycrypto`` and ``cryptography``. The same is true of data encrypted using ``cryptography``.
