Remarks

A digital certificate is a common credential that provides authentication. A trusted organization, called a Certificate Authority (CA), assigns a certificate to a user or entity who then uses the certificate to prove itself to the other side. The user or entity is able to do this using a digital certificate because the certificate contains information necessary for the client to authenticate the server, including the following information:

The Certificate Authority's name.
The entity to whom the certificate was issued.
The entity's public key.
The dates the certificate is valid.

Example

The following example demonstrates accessing a certificate and displaying info about it.

[Visual Basic]

Private Sub DisplayCertificateInfo(ByVal certNum as Integer)



   ' Create a new CertificateStore to access certificates

   Dim store as new CertificateStore(CertificateStoreLocation.LocalMachine, CertificateStore.My)



   Try

      ' Get the requested certificate

      Dim cert as Certificate = store(certNum)



      ' Display info about the certificate

      Dim msg as String

      msg+= "The following information about the certificate is available." + vbCrLF + vbCrLf

      msg+= "Name: " + cert.Name + vbCrLf

      msg+= "Description: " + cert.Description + vbCrLf

      msg+= "Expires: " + cert.ExpirationDate + vbCrLf

      msg+= "Issued: " + cert.IssueDate + vbCrLf

      msg+= "Issues to: " + cert.IssuedTo + vbCrLf

      msg+= "Serial number: " + cert.SerialNumber + vbCrLf

      msg+= "Version: " + cert.Versio

      MessageBox.Show(msg)

   Catch ex as Exception

      MessageBox.Show("Error. No certificate found at index " + certNum)

   End Try

End Sub

[C#]



private void DisplayCertificateInfo(int certNum)

{

  // Create a new CertificateStore to access certificates

  CertificateStore store = new CertificateStore(CertificateStoreLocation.LocalMachine, CertificateStore.My);



  try

  {

     // Get the requested certificate

     Certificate cert = store[certNum];



     // Display info about the certificate

     string msg = "";

     msg+= "The following information about the certificate is available.\r\n\r\n";

     msg+= "Name: " + cert.Name + "\r\n";

     msg+= "Description: " + cert.Description + "\r\n";

     msg+= "Expires: " + cert.ExpirationDate + "\r\n";

     msg+= "Issued: " + cert.IssueDate + "\r\n";

     msg+= "Issues to: " + cert.IssuedTo + "\r\n";

     msg+= "Serial number: " + cert.SerialNumber + "\r\n";

     msg+= "Version: " + cert.Version;

     MessageBox.Show(msg);

  }

  catch(Exception ex)

  {

     MessageBox.Show("Error. No certificate found at index " + certNum);

  }
