This is a fork from signalapp/curve25519-daleks fork from the original dalek-cryptography/curve25519-dalek repository. The original repository is a pure-Rust implementation of group operations on Ristretto and Curve25519. The signalapp/curve25519-dalek adds lizard encoding and decoding, but is not merged in the original repository or published on crates.io. Since libpep uses the lizard encoding, we forked the signalapp/curve25519-dalek repository and published it on crates.io, so that we can use it as a dependency in libpep.

Dalek elliptic curve cryptography

This repo contains pure-Rust crates for elliptic curve cryptography:

Crate	Description	Crates.io	Docs	CI
curve25519‑dalek	A library for arithmetic over the Curve25519 and Ristretto elliptic curves and their associated scalars.
ed25519‑dalek	An implementation of the EdDSA digital signature scheme over Curve25519.
x25519‑dalek	An implementation of elliptic curve Diffie-Hellman key exchange over Curve25519.

There is also the curve25519-dalek-derive crate, which is just a helper crate with some macros that make curve25519-dalek easier to write.
