* Add `Scalar` and `MontgomeryPoint` conversions - Adds `SigningKey::to_scalar` to extract the private scalar - Adds `VerifyingKey::to_montgomery` to map the verifying key's `EdwardsPoint` to a `MontgomeryPoint` - Also adds corresponding `From<&T>` impls which call the inherent methods. This is useful for systems which are keyed using Ed25519 keys which would like to use X25519 for D-H. Having inherent methods means it's possible to call these methods without having to import `Scalar` and `MontgomeryPoint` from `curve25519-dalek`. This is of course a bit circuitous: we could just multiply `Scalar` by `EdwardsPoint` and use the resulting `EdwardsPoint` as the D-H shared secret, however it seems many protocols have adopted this approach of mapping to `MontgomeryPoint` and using that for the shared secret, since X25519 is traditionally used for ECDH with Curve25519. * Add reference to eprint 2021/509 * Basic X25519 Diffie-Hellman test |
