Description j_pascoe@apple.com 2021-11-16 14:46:15 PST
In order to avoid needing to make and coordinate changes to ASC to support new fields or changes within ClientDataJSON and to maintain a single source of truth, calls to ASC from WebKit will contain a precomputed ClientDataHash.

This will especially be relevant if we choose to support Secure Payment Confirmation (SPC), which involves extending ClientDataJSON with payment related fields not relevant to AuthenticationServices (https://www.w3.org/TR/2021/WD-secure-payment-confirmation-20210831/#dictdef-collectedclientpaymentdata).
