X509RevocationMode Enumerazione

Definizione

Spazio dei nomi:

System.Security.Cryptography.X509Certificates

Assembly:

System.Security.Cryptography.dll

Specifica la modalità usata per selezionare i certificati X509 per la revoca.

public enum class X509RevocationMode

public enum X509RevocationMode

type X509RevocationMode = 

Public Enum X509RevocationMode

Ereditarietà

Object

ValueType

Enum

X509RevocationMode

Campi

NoCheck	0	Non viene eseguito alcun controllo di revoca sul certificato.
Offline	2	Viene eseguito un controllo di revoca mediante un elenco certificati revocati (CRL, Certificate Revocation List) memorizzato nella cache.
Online	1	Viene eseguito un controllo di revoca mediante un elenco certificati revocati online.

Esempio

L'esempio seguente apre l'archivio certificati personali dell'utente corrente, consente all'utente di selezionare un certificato, quindi scrive le informazioni sulla catena di certificati e certificato nella console. L'output dipende dal certificato selezionato.

//Output chain information of the selected certificate.
X509Chain ^ ch = gcnew X509Chain;
ch->ChainPolicy->RevocationMode = X509RevocationMode::Online;
ch->Build( certificate );
Console::WriteLine( "Chain Information" );
Console::WriteLine( "Chain revocation flag: {0}", ch->ChainPolicy->RevocationFlag );
Console::WriteLine( "Chain revocation mode: {0}", ch->ChainPolicy->RevocationMode );
Console::WriteLine( "Chain verification flag: {0}", ch->ChainPolicy->VerificationFlags );
Console::WriteLine( "Chain verification time: {0}", ch->ChainPolicy->VerificationTime );
Console::WriteLine( "Chain status length: {0}", ch->ChainStatus->Length );
Console::WriteLine( "Chain application policy count: {0}", ch->ChainPolicy->ApplicationPolicy->Count );
Console::WriteLine( "Chain certificate policy count: {0} {1}", ch->ChainPolicy->CertificatePolicy->Count, Environment::NewLine );

//Output chain information of the selected certificate.
X509Chain ch = new X509Chain();
ch.ChainPolicy.RevocationMode = X509RevocationMode.Online;
ch.Build (certificate);
Console.WriteLine ("Chain Information");
Console.WriteLine ("Chain revocation flag: {0}", ch.ChainPolicy.RevocationFlag);
Console.WriteLine ("Chain revocation mode: {0}", ch.ChainPolicy.RevocationMode);
Console.WriteLine ("Chain verification flag: {0}", ch.ChainPolicy.VerificationFlags);
Console.WriteLine ("Chain verification time: {0}", ch.ChainPolicy.VerificationTime);
Console.WriteLine ("Chain status length: {0}", ch.ChainStatus.Length);
Console.WriteLine ("Chain application policy count: {0}", ch.ChainPolicy.ApplicationPolicy.Count);
Console.WriteLine ("Chain certificate policy count: {0} {1}", ch.ChainPolicy.CertificatePolicy.Count, Environment.NewLine);

'Output chain information of the selected certificate.
Dim ch As New X509Chain()
ch.ChainPolicy.RevocationMode = X509RevocationMode.Online
ch.Build(certificate)
Console.WriteLine("Chain Information")
Console.WriteLine("Chain revocation flag: {0}", ch.ChainPolicy.RevocationFlag)
Console.WriteLine("Chain revocation mode: {0}", ch.ChainPolicy.RevocationMode)
Console.WriteLine("Chain verification flag: {0}", ch.ChainPolicy.VerificationFlags)
Console.WriteLine("Chain verification time: {0}", ch.ChainPolicy.VerificationTime)
Console.WriteLine("Chain status length: {0}", ch.ChainStatus.Length)
Console.WriteLine("Chain application policy count: {0}", ch.ChainPolicy.ApplicationPolicy.Count)
Console.WriteLine("Chain certificate policy count: {0} {1}", ch.ChainPolicy.CertificatePolicy.Count, Environment.NewLine)

Commenti

Questa enumerazione viene usata per specificare se si verifica un controllo di revoca e se viene eseguito online o offline.

Nota

La specifica di un controllo online può comportare un ritardo lungo mentre l'autorità di certificazione viene contattata.
