Support multiple ways to store credential PII and keys about identity-credential HOT 1 OPEN

// For each Credential Format, an instance of an implementation of this interface exist:
//   MdocDeviceRetrievalAdapter
//   MdocServerRetrievalAdapter
//   MdocDirectAccessAdapter
//
// The application will instantiate these at startup.

interface CredentialAdapter {

  // At provisioning time
  fun provisionData(credential: Credential, pii: NameSpacedData)

  // At periodic intervals, this is called to e.g. refresh MSO
  fun periodicRefresh()

  // At presentation time, application can query whether a [CredentialStorageAdapter]
  // supports the given [Credential]

// Each [CredentialAdapter] implementation contains specific methods to
