Accepting invalid SSL certificates using WinRT

问题:

There are scenarios where you want your application to accept invalid SSL certificates (testing environment/ self signed certificates etc).

In the .NET world one would use the ServerCertificateValidationCallback class to do so. Unfortunately the class doesn't exist in a WinRT context.

I need to consume a Web API using WinRT which is hosted on a server without a valid ssl certificate.

How do you accept invalid ssl certificates in WinRT using the HttpClient class or any other appropriate class.

Any help or alternatives would much appreciated.

in silverlight, it wasn't allowed. I haven't seen anything that says it's allowed in winrt.

The following code worked for me for the debugging scenario:

var filter = new HttpBaseProtocolFilter();
#if DEBUG
    filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.Expired);
    filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.Untrusted);
    filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.InvalidName);
#endif
using (var httpClient = new HttpClient(filter)) {
    ...
}
