x25519

The `x25519` library (version 0.0.2) provides a pure Python implementation of the Curve25519 elliptic curve for Diffie-Hellman key exchange. It was last released in October 2021 and appears to be unmaintained, with no active development or official GitHub repository discoverable at the provided link. This library is distinct from the more robust and actively maintained X25519 implementations found in the `cryptography` library.
