X509Certificate Class
.NET Framework 2.0
Provides methods that help you use X.509 v.3 certificates.
Namespace: System.Security.Cryptography.X509Certificates
Assembly: mscorlib (in mscorlib.dll)
Assembly: mscorlib (in mscorlib.dll)
'Declaration <SerializableAttribute> _ <ComVisibleAttribute(True)> _ Public Class X509Certificate Implements IDeserializationCallback, ISerializable 'Usage Dim instance As X509Certificate
/** @attribute SerializableAttribute() */ /** @attribute ComVisibleAttribute(true) */ public class X509Certificate implements IDeserializationCallback, ISerializable
SerializableAttribute ComVisibleAttribute(true) public class X509Certificate implements IDeserializationCallback, ISerializable
ASN.1 DER is the only certificate format supported by this class.
For most scenarios, you should use the X509Certificate2 class instead.
The following example loads an X.509 certificate from a file, calls the ToString method and displays the results to the console.
Imports System Imports System.Security.Cryptography.X509Certificates Module X509 Sub Main() ' The path to the certificate. Dim Certificate As String = "Certificate.cer" ' Load the certificate into an X509Certificate object. Dim cert As New X509Certificate(Certificate) ' Get the value. Dim resultsTrue As String = cert.ToString(True) ' Display the value to the console. Console.WriteLine(resultsTrue) ' Get the value. Dim resultsFalse As String = cert.ToString(False) ' Display the value to the console. Console.WriteLine(resultsFalse) End Sub End Module
