Hinweise

Wenn sich das Zertifikat im Paket befindet NotEmbedded , muss eine Anwendung, die Signaturen überprüft, eine Kopie des Zertifikats bereitstellen, um die von diesem signierten Signaturen zu überprüfen.

InSignaturePart fügt zwei Informationselemente <KeyName> und <KeyValue>als Teil des Felds der KeyInfo gespeicherten digitalen Signatur hinzu. Die <KeyName> Elemente und <KeyValue> werden nicht im Rahmen der Signaturüberprüfung verarbeitet und sind daher nicht sicher vor Änderungen. Anträge sollten keine Annahmen hinsichtlich der Gültigkeit dieser beiden Elemente treffen. Um unentdeckte Änderungen und mögliche Verwirrungen zu vermeiden, sollten Anwendungen die InCertificatePart Option anstelle von InSignaturePartverwenden. Die InCertificatePart Option bietet oder macht weder noch <KeyName><KeyValue>verfügbar.
