How to validate a server certificate programmably

[Silan]

When we double click a .cer certificate file, a certificate dialog will be popped up. If the certificate has anything wrong the dialog will show a warning message

Is there a method in the .NET class library which could do such a validation checking and return a boolean

Have a look at the ICertificatePolicy interface in System.Net. It has one method that allows you to validate or deny a server certificate. A simple implementation would just return..

serverCertificate.Equals( publicKeyCertficate ), where you provide the X509Certifcate of publicKeyCertificate in the constructor ofyour implementaion

You hook this up with the ServicePointManager.CertificatePolicy property in your application

hope this helps
