I don't see any of the protocols using SLH-DSA/ML-DSA leverage the context—for instance, it is set to an empty string in draft-ietf-lamps-cms-sphincs-plus, draft-ietf-lamps-x509-slhdsa, and draft-ietf-cose-sphincs-plus (where use of context is not specified). -Tiru > After all, ML-DSA and SLH-DSA share the interface design, which is > beyond the capabilities of Ed25519ctx and Ed448, let alone Ed25519. > > And with regards to precedent, Ed25519 does not support contexts. > Ed25519ctx is the version where I hacked in context support, but > very few things support that.
