CryptographicException mit Dienstkonto p12-Datei

Question

Ich versuche, mich mit einer Dienstkonto-P12-Datei bei meinem Google Analytics-Konto zu authentifizieren. Der unten stehende Code sollte für mein Analytics-Konto authentifiziert werden und die benötigten Daten anfordern. Ich erhalte jedoch einen Fehler mit dem X509Certificate2, wenn ich den folgenden Code ausführe. Ich habe meine p12-Datei in bin/debug-Ordner meines Projekts mit angegebenen Anmeldeinformationen abgelegt.

var certificate = new X509Certificate2(keyFilePath, keyPassword, X509KeyStorageFlags.Exportable); 

Ich erhalte die folgende Fehlermeldung:

An unhandled exception of type 'System.Security.Cryptography.CryptographicException' occurred in mscorlib.dll

Bitte helfen Sie mir. Was ich hier vermisse. Jede Hilfe wird geschätzt.

Answer 1

Ich habe Probleme mit der P12-Datei in der Vergangenheit gesehen. Ich muss das Problem noch vollständig diagnostizieren können. Manchmal ist es einfach einfacher, die .json-Datei des Dienstkontos herunterzuladen. Google ruft p12 trotzdem rückwärtskompatibel auf, damit sie eventuell keine p12-Dateien mehr verwenden.

Dies ist die Methode, die ich für die Authentifizierung eines Dienstkontos verwende. Es wird herausfinden, welche Art von Anmeldeinformationen Sie senden.
