Hash Demographics
POST /hash
This operation uses the local hashing service base URL, independent of the Identity API.
Clients using privacy-preserving (blinded) mode will have their own local hashing service instance. This service takes unblinded demographics information and returns a hashed payload for use with the blinded Identity API methods. See Privacy-Preserving (Blinded) Mode for details.
