ChaCha20Poly1305 Reusable for Asyncio

This library provides a Python implementation of the ChaCha20Poly1305 authenticated encryption algorithm, specifically designed for asynchronous I/O (asyncio) contexts. While it aimed to offer a reusable cipher object for efficiency, it is now considered obsolete for new projects due to the `cryptography` library's adoption of a high-performance, Rust-based ChaCha20Poly1305 implementation. The library is currently at version 0.13.2, with recent maintenance releases, but its utility for new development is superseded.
