Accept self-signed TLS/SSL certificate in VB.NET

Question

I'm searching for a way to validate (or bypass validation for) self-signed SSL certificates using VB.NET. I found code to do this in C# and tried converting it into VB code, but I'm not having any luck.

Here is the C# code: How do I use WebRequest to access an SSL encrypted site using https?

Here is what I tried:

Imports System Imports System.Net Imports System.Security.Cryptography.X509Certificates  Public Class clsSSL     Public Function AcceptAllCertifications(ByVal sender As Object, ByVal certification As System.Security.Cryptography.X509Certificates.X509Certificate, ByVal chain As System.Security.Cryptography.X509Certificates.X509Chain, ByVal sslPolicyErrors As System.Net.Security.SslPolicyErrors) As Boolean         Return True     End Function End Class 

Then before the WebRequest I have this line of code which gives me an error.

ServicePointManager.ServerCertificateValidationCallback =     New System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications) 

The error message is:

Delegate 'System.Net.Security.RemoteCertificateValidationCallback' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor.

Answer 1

In VB.Net, you need to write

ServicePointManager.ServerCertificateValidationCallback = AddressOf AcceptAllCertifications
