// The types in this file define a normalized identifier representation of the data found in the CCADB and that
// found in OneCRL. This sort of normalization is required
// largely because the CCADB contains all relevant information (via holding a copy of the
// certificate itself), however OneCRL has only either a combination of the IssuerName:SerialNumber
// or the SubjectName:KeyHash as identifying information (and the CCADB does not know which type it holds).
//
// So if you want check whether or not an entry from the CCADB is present in OneCRL, you must
// obtain both its IssuerName:SerialNumber AND SubjectName:KeyHash values and lookup OneCRL for
// either (because there is no information in the CCADB as to which one it is in OneCRL).
