i am looking to get the data from any given domain names SSL certificate. For example I want to put in any website address e.g. "http://stackoverflow.com" and my code would firstly check if an SSL certificate exists. If it does then I want it to pull out the expiry date of the certificate. [ i am reading Domainnames from DB ] Example :http://www.digicert.com/help/
i need to create a web service to check expiry date. how can i implement it?? - I have looked up loads of different things such as RequestCertificateValidationCallback and ClientCertificates etc.
I could be completely wrong (hence why I need help) but would I create a HTTPWebRequest and then somehow request the client certificate and specific elements that way?
i tried the example provided @SSL certificate pre-fetch .NET , but i am getting forbitten 403 error.
