Specifies the mode used to check for X509 certificate revocation.

Namespace:   System.Security.Cryptography.X509Certificates
Assembly:  System (in System.dll)

public enum class X509RevocationMode

Member nameDescription
NoCheck

No revocation check is performed on the certificate.

Offline

A revocation check is made using a cached certificate revocation list (CRL).

Online

A revocation check is made using an online certificate revocation list (CRL).

This enumeration is used to specify whether a revocation check occurs and if it is performed online or offline.

System_CAPS_noteNote

Specifying an online check can result in a long delay while the certificate authority is contacted.

The following example opens the current user's personal certificate store, allows the user to select a certificate, then writes certificate and certificate chain information to the console. The output depends on the certificate you select.

//Output chain information of the selected certificate.
X509Chain ^ ch = gcnew X509Chain;
ch->Build( certificate );
Console::WriteLine( "Chain Information" );
ch->ChainPolicy->RevocationMode = X509RevocationMode::Online;
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 );
