C# - Error In HTTPS For Self Signed Certificate

Oct 11, 2010

This is in VS 2005. And IIS is 6.0. I am trying to use Self signed certificate for HTTPS. In the code i am redirecting from http to https for few pages. It is nt working fine. and in the IIS manager, for each page that i want HTTPs, i have changed its setting by checking "Require Secure Channel(SSL)" and "Require 128 bit encryption".

public void setSecureProtocol()
string redirectUrl = null;
bool bSecure = true;
bool SecureConnection = true;
if (bSecure && SecureConnection)
redirectUrl = Request.Url.ToString().Replace("http:", "https:");
if (!bSecure && SecureConnection)
redirectUrl = Request.Url.ToString().Replace("https:", "http:");
if (redirectUrl != null)

Pages throw me an error like this The page must be viewed over a secure channel The page you are trying to access is secured with Secure Sockets

Layer (SSL).

Please try the following:

* Type https:// at the beginning of the address you are attempting to reach and press ENTER.

HTTP Error 403.4 - Forbidden: SSL is required to view this resource. Internet Information Services (IIS)Internet Information Services (IIS) When i try to put https in the start of the URl, it wont call. I have no idea whats wrong in here. Here, Its not redirecting from http to https. For the pages that i am not redirecting in the code behind, and changing in the IIS, i can see the HTTPS when i check the two checkboxes.

Set Up HTTPS / SSL Certificate For Our Website On Another Server

Mar 30, 2011

There are 2 web-servers involved:

Webserver1 has been in the organization a few years and is hosting/running multiple websites with https encryption (,, etc). It has a valid, signed certificate.

Webserver2 is a new server, for which I am responsible. I am tasked with setting up https and getting the certificate, etc. It has a web app running on it, but it does not have a domain name (only has an IP address)...which as I recently learned, is a requirement for a signed certificate.

What I'd like to know is this -- is it possible to set up a site on Webserver1 that points to the site I'm hosting on Webserver2 (ie which also utilizes the Webserver1's signed/verified certificate?

C# - Can't Connect To HTTPS Using X509 Client Certificate

May 24, 2010

I'm new to cryptography and I'm a bit stuck:

I'm trying to connect (from my development environment) to a web service using HTTPS. The web service requires a client certificate - which I think I've installed correctly.

They have supplied me with a .PFX file. In Windows 7, I double clicked the file to install it into my Current User - Personal certificate store.

I then exported a X509 Base-64 encoded .cer file from the certificate entry in the store. It didn't have a private key associate with it.

Then, in my app, I'm attempting to connect to the service like this:

var certificate = X509Certificate.CreateFromCertFile("xyz.cer"));
var serviceUrl = "https://xyz";
var request = (HttpWebRequest) WebRequest.Create(serviceUrl);
request.Method = WebRequestMethods.Http.Post;
request.ContentType = "application/x-www-form-urlencoded";

I get a 502 Connection failed when I connect.

Is there anything you can see wrong with this method? Our production environment seems to work with a similar configuration, but it's running Windows Server 2003.

SSL Certificate Type Required For PayPal HTTPS Web Service (Payments Pro SOAP / NVP)

Feb 25, 2011

We set up a paypal gateway on our site using paypal NVP API: Our IIS web server is set up for SSL, though I just created a cert on the locally machine. When we load HTTPS the browser gives a warning about security before the page will load. I know a local cert won't cut it for SSL, so I think we need a verisign cert? [URL] Is this correct? How can I know that the cert I am getting will get along with paypal and elimante any security warnings for the user.

Security :: When To Use An Ssl Certificate

Jan 23, 2011

If I'm taking a password on a page, should that page be served via https and exactly how dangerous is it not to? I've tried googling this but every guide just says that ssl certificates "stop hackers seeing sensative data" with no real description of how they would do this or exactly how vulnerable your site is as a result of not having ssl.Could someone summarize how easy it is for someone to steal passwords on non-https pages? Should i even be considering doing a login page without one?

Security :: Get Remote SSL Certificate Information?

Nov 27, 2010

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. "" and my code would firstly check if an SSL certificate exists. If it does then I want it to pull out the Issuer, Subject, Valid From and Valid Until etc. The intention is to create an SSL certificate checker similar to this: [URL]

How can I do this - I have looked up loads of different things such as RequestCertificateValidationCallback and ClientCertificates etc.

would I create a HTTPWebRequest and then somehow request the client certificate and specific elements that way?

Security :: SSL - Programitically Locate SSL Certificate?

Mar 11, 2010

This is my first time stepping into the wonderful world of SSL. I am working on a project which forces the HTTPS protocol/ Url Scheme for certain parts of the site. I mananged to get that working fine.


There is another part of the project where I pull binary image data from a database, and then write/render the image onto the browser window. <b>I found that since I converted the site to SSL, the rendering no longer works</b>. I am now working under the believe that I must open my a System.Net.Security.SSLStream in order to stream the bytes to the Response.

<br/>I'm at the point where I am writing the SSLStream, but there is a major roadblock. I don't know how to
programmatically locate my X509Certificate so that I can authenticate the SSLStream. To make this problem a little more challenging, I am working with a somewhat-unpopular shared hosting provider, who does not give me access to the certificate name - which probably is not a big deal. I am guessing I'm just going about this problem the wrong way. <br/>

Security :: Using A X509 Certificate In A Web-service

Jun 17, 2010

I have a rather strange situation that I am in.

I have to write a web-service that will (among other things) communicate with another web service. When we communicate with that remote web-service we are required to use a certificate that they provided.

I am having a really hard time trying to find any sample code that does this.

I have found code for installing certs when you want to use a browser to communicate, but none when you are using a web-service to web-service and you are required to HAVE the certificate, not requiring the OTHER end to have the certificate.

So far I cannot even find code to allow me to parse throught the cert store. Samples I found online show up as errors in Visual Studio 2005.

Note: This is running one Windows 2000, designed with Visual Studio 2005, 2.0
