Question

I am writing a test to test a service I am deploying, to bypass the ssl cert check I implemented an ssl override using the snippet below:

public static void SSLValidationOverride()
        {
            ServicePointManager.ServerCertificateValidationCallback = new                  RemoteCertificateValidationCallback(OnValidationCallback);
        }
private static bool OnValidationCallback(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors errors)
{
if (cert.subject == MyCertSubject)
       return true;
else
       return false;
}

Now I have to call another webservice using ssl in the code and want to switch to default ssl check before calling that. What’s the best way to do that. MS help says the default value of ServicePointManager.SecurityProtocol is null(http://msdn.microsoft.com/en-us/library/system.net.servicepointmanager.securityprotocol.aspx). Will setting it to null switch to default ssl validation and is there any other way to do this.

Answer 1

I ended up setting ServicePointManager.SecurityProtocol to null and it works fine. Though am still open to better ways to do this

public static void SSLValidationRestore()
        {
            ServicePointManager.ServerCertificateValidationCallback = null;
        }
