Implementation of the XEdDSA signature algorithm

XEdDSA is an Elliptic-Curve signature algorithm designed by the Signal project. XEdDSA is designed to use the same Elliptic-Curve keys both for Diffie-Hellman key exchange and for EdDSA signatures.

Features

The following features of the specification are implemented:

  • Utility functions to implement specific algorithms
  • Concrete implementation for XEd25519 (on Curve25519, compatible with curve25519-dalek)
