Encryption
**********
The Encryption Operator uses the :ref:`Plugins` interface.
This operator uses `libsodium <https://doc.libsodium.org/>`_ for encrypting and decrypting data.
If ADIOS can find libsodium at configure time, this plugin will be built.
This operator will generate a secret key and encrypts the data with the key and a nonce as described in the libsodium `secret key cryptography docs <https://doc.libsodium.org/secret-key_cryptography/secretbox>`_.
The key is saved to the specified ``SecretKeyFile`` and will be used for decryption. The key should be kept confidential since it is used to both encrypt and decrypt the data.
Parameters to use with the Encryption operator:
