Low-level CFFI bindings for Argon2

argon2-cffi-bindings provides low-level CFFI bindings to the official implementation of the Argon2 password hashing algorithm. It is primarily intended to be used as a backend dependency for high-level Python packages like `argon2-cffi`, and is not recommended for direct application password hashing. The library is actively maintained and currently at version 25.1.0, with regular releases aligning with updates to the underlying Argon2 C library and Python ecosystem changes.
