X509RevocationMode Enumeration
.NET Framework (current version)
Specifies the mode used to check for X509 certificate revocation.
Assembly: System (in System.dll)
| Member name | Description | |
|---|---|---|
| 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.
Note |
|---|
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 = new 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);
