Example
The following code example opens the My certificate store for the currently logged in user and then searches for a particular X.509 certificate using the certificate's key identifier.

' in user.
Dim store As X509CertificateStore

Dim cert As Microsoft.Web.Services2.Security.X509.X509Certificate = Nothing
Dim certKeyID() As Byte
