I'll install a SSL Certificate on my IIS Server to secure my website. The entire site will be under HTTPS.
The website is currently done and working good in HTTP.
Should I change something on scripting or database connections? Or the certificate do not change anything on my website's operation?
I have a WCF service which accepts X.509 certificate signed incoming messages. As per my understanding the client will send the message with signature encrypted using his private key and web services will decrypt the signature with client's public key. This ensures that the sender of the message is holder of the private key and that he is certified by the server trusted CA as "He is what he claims to be".
It's being a highly secure application I need to give access to only certain clients regardless of whether they are trusted or not. (This is to take care of good turned bad scenario :-)) How do I achieve this? Is there any way to get the client information as subject name etc from his certificate in C# code? Is there any example of this usage?
Let's assume our users in their office using Internet explorer to sign some Web Pages using their client certificate imported into the Internet explorer browser (let s assume no other browser is used)
what is a good approach/architecture for validating the client certificate (Internet Explorer), how to send that certificate or the signed form to the server and how do we verify the signature
Should we use smart client approach integrated to the web application or some silverlight or so or is web form/web pages enough to implement this security requirement ?
I have a list of attendees. I have a certificate template.
I need to print one certificate for each attendee and all the certificates should be printed by just one button click.
We have a large extranet asp.net application that users forms authentication. In addition, for SCCM purposes, each computer in the company has a client certificate installed.
Now the question has been raised:
Is it possible for us to test for the presence of this certificate from our asp.net code behinds?
We don't want to switch our security to require client certificates to access the site, there are just parts of some pages that we'd rather not display if the person viewing the site is not using a company issued machine.
when sending email the' asp.net 2.0 i get the above error msg The remote certificate is invalid according to the validation procedure. how to rectify this error msg soemetmes i get this error msg also Mailbox unavailable. The server response was:: bosauthsmtp15: Host :No unauthenticated relaying permitted

We have a controlled list of the users (It s an Extranet solutions for our collaborators)
We need to develop some new web pages (not all) some of which require the user accessing the web page to fill out some form and sign it using his digital signature/certificate. Each customer has their own certificate which he has on his computer (either as a local desktop file or the certificate may be probably integrated into the browser certificates via browser advanced options).
In other words:
1- Allow a client visiting some of the web pages to digitally sign the form before submitting it to our web server (the signature is his specific certificate)
2- Send either the form and the certificate or the html encrypted with his certificate to the web server
3- Read and identify the certificate on the web server (C# code)
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?

View 1 RepliesI am trying to use an X509Certificate within an ASP.NET web service within the Rackspace Cloud. I have a feeling the certificate stores on the cloud nodes maybe causing problems. I also have a question related to this with the exception that I am receiving at SslStream.AuthenticateAsClient Exception when using iPhone Apple Push Notification Provider (apns-sharp) C# Within the apns-sharp project I was using the following code:
certificate = new X509Certificate2(p12File)
However I received an exception and changing the code to the following resolved the X509Certificate2 exception. The new code is as follows:
certificate = new X509Certificate2(p12File, String.Empty, X509KeyStorageFlags.MachineKeySet);
I would like to know if I can use an X509Certificate2 within ASP.NET without using a certificate store? Would the certificate stores be causing problems with the Rackspace Cloud nodes?
Update #1 Rackspace tell me that access to the Local Machine Certificate store is not permitted. Is there any other way to bypass using the certificate store? Maybe using a third party library?
how do you validate the digital certificate SSL? so that you know the response came from the correct website?

View 1 RepliesThis 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:");
else
if (!bSecure && SecureConnection)
redirectUrl = Request.Url.ToString().Replace("https:", "http:");
if (redirectUrl != null)
Response.Redirect(redirectUrl);
}
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.

I want to get the certificate information of a website. I means that i've a textbox on a page. When i enter a url in that textbox and press the button. The certificate information of that website should be returned.
Say, i've entered the [URL], Then it should return the Certificate authority, Validation period etc.
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. "www.asp.net" 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 ASP.net???? - 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?
There are 2 web-servers involved:
Webserver1 has been in the organization a few years and is hosting/running multiple websites with https encryption (app1.ourcompany.com, app2.ourcompany.com, 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 SiteOnWebserver2.ourcompany.com) which also utilizes the Webserver1's signed/verified certificate?
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.
<br/>
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/>
I have created an x590 certificate that is in the file :

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, asp.net 2.0
I am trying to use the X509FindType.FindBySubjectDistinguishedName option and I am not sure where to find the value for the findValue property in my config.
