Make Curve25519 PublicKeys conform to
HashableN.B. Merge open PR #173 first (or if #173 is closed, close this one too), since this PR builds on top of that.
Checklist
If you've made changes to
gybfiles.script/generate_boilerplate_files_with_gyband included updated generated files in a commit of this pull requestMotivation:
PublicKey's are fundamental building blocks within EC-oriented code bases. They can act as a natural key in Dictionaries and otherwise important property of larger structs, which us developers often would like to make
Hashable. Today, Curve25519 public keys prevent auto-synthesis ofHashablefor any structs they are members of, thus Curve25519 keys ought to beHashable!This poses no security risk nor any performance downgrade.
This PR is an addition of open PR #173.
Modifications:
Curve25519.KeyAgreement.PublicKeyandCurve25519.Signing.PublicKeyhave been madeHashableand unit tests have been added.Result:
Curve25519.KeyAgreement.PublicKeyandCurve25519.Signing.PublicKeyare nowHashable
