+At present the creation of the verification hash is delegated to the
+cryptographic suite specification when generating and verifying a proof. It is
+expected that this algorithm is going to be common to most cryptographic suites.
+It is predicted that the verification hash generation algorithm will eventually
+be defined in this specification.
