We currently offer:

  • Schnorr in DLEq (quality transcript, batch verification on a passed in batch verifier)
  • Schnorr in FROST (similar properties, yet manages the batch verifier itself)
  • A modular HRAm in FROST for its modularity

Ideally we have one Schnorr crate supporting:

  • A modular HRAm
  • R, s Schnorr Signatures
  • c, s Schnorr signatures via re-calculation of c (I don't care to offer an enum for the Schnorr signature nor variadic return types)
  • Batch verification against an existing batch verifier
  • Batch verification with its own batch verifier (sugar)
  • Sugar for Schnorr over an existing transcript (using a quality transcript) and sugar for Schnorr as an isolate (with a classical HRAm)

With DLEq and FROST both deferring to it.

We need custom generator Schnorr .-. I'd like to move this after #84.
