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.

Private Function GetCertificateUsingKeyIdentifer(ByVal IsTokenForSigning As Boolean) As Microsoft.Web.Services2.Security.X509.X509Certificate
    ' Open up the My certificate store for the currently logged
    ' in user.
    Dim store As X509CertificateStore
    store = X509CertificateStore.CurrentUserStore(X509CertificateStore.MyStore)
    Dim open As Boolean = store.OpenRead()


    Dim cert As Microsoft.Web.Services2.Security.X509.X509Certificate = Nothing
    Dim certKeyID() As Byte
    If IsTokenForSigning Then
        certKeyID = New Byte() {&H48, &H1B, &HE8, &HEC, &HBD, &H32, &HC, &HD6, &H39, &HA8, &H9B, &HCE, &HEA, &H5A, &H2A, &HE4, &H66, &H76, &H62, &H42}

    End If
    ' Search for a certifacte based on the
    ' certificate's key identifier.
    Dim certs As X509CertificateCollection = store.FindCertificateByKeyIdentifier(certKeyID)

    If certs.Count > 0 Then
        ' Obtain the first matching certificate.
