ChaCha-Daence is a deterministic authenticated cipher built out of ChaCha and Poly1305 with good performance and high security even for extremely large volumes of data. chachadaence.py is a Python illustration of ChaCha-Daence, NOT FIT FOR USE IN PRODUCTION, based on the pyca cryptography.io library.

• WARNING: Daence is new and this software has only been lightly tested.

WARNING: This is ONLY FOR ILLUSTRATION. The pyca cryptography.io library doesn't provide HChaCha, and although it provides the ChaCha core function, which can be used to compute HChaCha, there's no straightforward way in Python to safely compute the 32-bit additions needed to compute HChaCha from ChaCha.
