May 12, 2010
I am using username authentication for client and certificate authentication for service. Am done with installing the certificates and i have root authority in my perosnal local store and CRL in trusted root folder. everything was fine until i added client. When i tried to add client, its giving me the error"
The X.509 certificate CN=tempCert chain building failed.
The revocation function was unable to check revocation for the certificate

I have searched and could not find any article related to "How to implement Certificate Security in
production environment".
I could able to Create sample certificates for client and Server on my local machine and was able to authenticate my client app with the certificates . These certificates are test certificates.
How do I do this in Production. We have a domain certificate from GoDaddy which resides on the server. How do I create a Client Certificate off of that.

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?

I need to add a cert. for the NetworkService account as this is what Identity of my App pool is set to, but I'm not sure how to go about doing that. Here's the steps, I take: Bring up the run command and submit "mmc"When the Management console appears I click on File > Add/Remove snap-in.Select Certificates and click AddSelect Service Account, click Next twice Then I'm presented with a bunch of Service Accounts. The ones that kind of resemble what I'm looking for are: Network Access Protection AgentNetwork ConnectionsNetwork List ServiceNetwork Location AwarenessNetwork Store Interface Service Out of the choices above, Network List Service would be my best guess.

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?

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 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 have few queries regarding installation of SSL certificate.How much time will it take in installing the SSL certificate and getting the IIS https enabled?
Is there any risk involved with the installation of SSL certificate that might bring down the applications hosted on the IIS.Will the application hosted on that IIS continue working with HTTP?(I don't want each application to be https enabled.

We have two different users and we want to authenticate them through "IIS Client Certificate Mapping Authentication" in IIS 7. They have certificates issued by VeriSign.When user requests a website, a pop-up appears on their browser to select a certificate. User can see both certificates and selects one of them and hit ok.We could capture Certificate attributes using
following code
HttpClientCertificate cs = Request.ClientCertificate;
Response.Write("ClientCertificate Settings:<br>");
Response.Write("Certificate = " + cs.Certificate + "<br>");
until now every thig is fine.We mapped one of two certificates to an AD user using this
"Configuring One-to-One Client Certificate Mappings".http://learn.iis.net/page.aspx/478/configuring-one-to-one-client-certificate-mappings/I am trying to print if user is authenticated or not using following code. and it is never authenticated. I don't know what mapping does. It seems it does nothing.Response.Write (Request.ServerVariables["LOGON_USER"]) ;
Response.Write ("<BR>") ;
Response.Write ("AUTH_USER: ") ;;
Response.Write(Request.ServerVariables["AUTH_USER"]);
Response.Write ("<BR>") ;
Response.Write("IsAuthenticated :" + User.Identity.IsAuthenticated + "<br>");
Response.Write("HttpContext.Current.User.Identity :" + HttpContext.Current.User.Identity.IsAuthenticated + "<br>");
Response.Write("Request.IsAuthenticated :" + Request.IsAuthenticated + "<br>");
Can somebody help so that I can allow user only if he supplies a certificate that is mapped to a user. Currently any user having a certificate can get into the site, site is having anonymous authentication and certificate is required.

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'm working on a project for a large company that wants to create a crypto toolbox for cross-platform signing and encrypting and am constantly running into problems concerning the cryptographic abilities in the .Net framework. The blazing inferno that I need to put out this time is that SignedCms and EnvelopedCms don't seem to work with a Cryptographic Service Provider that doesn't store the private-key on the Windows machine. I'm working with a network HSM and certicates that have only a public key, that is, no private-key and no information in the store as to where that private-key resides or how you can access it (a RSA public/private key pair is created on the machine, using the HSM supplier's CSP, and a certificate signing request is generated and used to create a public-key certificate signed by the CA). Theoretically the private key gets picked up from the HSM (referenced actually) using the CspParameters given when instantiating the class, which specifies the CSP provided by the HSM supplier. Unfortunately, up to now this only works with CAPI, where can associate the cryptographic service provider with the signing certificate (usign CertSetCertificateContextProperty with CERT_KEY_PROV_HANDLE_PROP_ID). (We're using CAPI for PKCS#7 signing because the .Net framework only supports signatures up to SHA1 and we have a minimum of SHA256). Surprisingly enough CmsSigner accepts a CSP in it's constructor but it cannot get the key, it throws an exception during instantiation from method CreateDummyCertificate for some reason (with the message "Process completed." no less!??). I use the following CspParameters:
[Code]....
CmsSigner cmsSigner = new CmsSigner(cspParams);
This process works great with certificates and key pairs created by MakeCert. With MakeCert you can associate the CSP information with the Certificate upon creation (-sk, -sp, -sy). The private key still resides in the HSM but specifying the provider during the creation of the certificate seems to have persisted the CSP information somewhere, somehow. Exactly how that's done I don't know, but if could do that, my problem would be solved.

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?

I dont have a lot of background with SSL and X509 configuration and support with my Asp.Net application, so I was wondering if someone can explain or point me in the right direction to MSDN or any other article or posting explaining if it's possible to do what I am looking to support in my environment.
I have IIS 6.0 with SSL (Verisign cert) as well as "Require client certificates" working against a local installation of Microsoft Certificate Services, https://<domain>/certsrv, where users can request and install client certs (both xp clients for basic
mode, and Vista/7 for advance mode).
Here's what I am up against:
I have a segment of users coming from a virtualized server environment where this environment does not store personal settings for more than 48 hours. It's not an internet cafe, but rather an actual business where their IT staff uses server images to reimage each virtual server in the farm every 48hrs. Thus losing all users data in the "Current Users" Certificate Stores.
The IT staff give users a network folder share to store any personal items (docs, spreadsheets, links, etc.). The servers consist of Windows Server 2003, and will be migrating to Windows Server 2008 in the next 6-9 months.
These users have rights in Internet Explorer to navigate to my certsrv site and use activex to to request and install certificates then clode and reopen the broser to navigate and render the asp.net app.
Problem:
It's a pain to ask the users to request and have issued a client certificate every 48 hours.
The IT staff of this company has asked if I can create some sort of certificate that they can load in the "local computer" certificate store, NOT the "Current User" store, that will be made part of their base image for all their servers, and that this certificate is then used to properly authenticate all users on these servers to my IIS with "require client certificates" selected.
Question:
Is this possible, and if so what can I do on my side to create the proper certificate to give to the IT staff at this business to put into their servers "local computer" certificate store? I assume either under the Personal->Certificates store, or under the "Trusted Root Certification Authorities"->Certificates store. Thus allowing any user of these servers in their thin client virtual environment to open I.E., navigate to my site and select a certificate from the "Choose a digital certificate" popup that allows them to render my Asp.Net application, or avoids this popup altogether.
If this is the wrong forum to post in, please advise and I will move. Probably due to vernacular on my part, I have been unable to find any resources on here, MSDN or Bing to help me solve this problem.

I need to send a X.509 client certificate to a web service in byte array (not attached to request). Besides the certificate, the caller will also send data and signed data. From the web service I can verify if the signature is ok but I don't know what is required to verify that the certificate is ok. I have the client certificate issuer CA trusted in Server (where the web service runs).
More specifically, how can I verify if a X.509 certificate itself is valid? I need to do it in web service not from IIS.

I would like to identify users that connect on a intranet web server (IIS) with client certificates.
I've set up a CA server on a Windows 2003 server pc. On my development pc, i've a windows xp with a web server (IIS) running.From my web server, i generated a certificate request (i specified the netbios name of my web server because this setup is for an intranet), i used that request to generate a web server certificate and i installed it on my IIS to allow SSL connection. . Now, i can connect with https to my web server from an internet explorer. I configured the web server to 'require client certificates'.
I would like to authenticate the users with a client certificate installed on each users pc. My CA server allows users to request a client certificate (domain user) from the CA server just by typing the url of the CA server and click 'User Certificate', 'submit' and then 'Install this certificate'.
In order to test my setup, i opened a Internet Explorer from a pc which resides in the domain and i requested and installed the user certificate. Then i connected to my web server and i get a window with the title "Choose a digital certificate". This window is always empty and never proposes the client certificate i previously installed on the user pc.
I've no idea of what i missed during my setup. I'm still wondering how the browser knows how to select which certificate must be displayed according to the url typed in the address bar.

I'm calling an external Web service that requires a certificate to be passed. This works perfectly fine for a stand-alone Windows Forms application, but when I attempt to do the exact same thing through an ASP.NET Web Application, it throws the following error:
"No connection could be made because the target machine actively refused it"
I found this MS article that describes what appears to be the exact issue I'm having, but it only applies to .NET 1.0:
[URL]
I'm using .NET 3.5, so surely it must be fixed by now!
I've attempted to change permissions on the certificate and fooled around with the app pool identity, but nothing seems to work.
