[Code]...
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
Am facing problem while consuming a java web service using WCF. below is the web.config and aspx.cs file details
Requirement
Service request and response will be encrypted with certificate. when i run this below code am getting the error "The private key is not present in the X.509 certificate."

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'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.
If I buy a CA certificate for the one site on the webserver, can I use the same certificate on a self-hosted wcf service.
The wcf service will use wsHttpBinding with username/password authentication.
I'm trying to receive a Client Certificate in a Web Service and having some problems.
Client
[Code]....
The certificate seems to be correclty loading and added to the client.
The client connects to the server with HTTPS.
Server:
[Code]....
cert.IsPresent is false and all certificate fields are empty.
IIS is configured to Accept Client Certificates.
Reproduced in two environments:
- Windows 7 x64, IIS 7, VS 2008, .NET 3.5
- XP x86, IIS 5, VS 2008, .NET 3.5
Always in the Web Service the Client Certificate is not proesent. I haven't been able to find any other configuration I should do.
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.
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.
View 1 RepliesIf 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 2 RepliesI 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.
View 1 RepliesI 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?
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 :
"C:UsersmartinAppDataRoamingMicrosoftSystemCertificatesMyCertificates"
I am trying to acces the public key to encrypt some plain text.
The system is throwing an "System.ArgumentOutOfRangeException" at the line
Dim certificate As X509Certificate2 = certificateCollection(0)
Can anyone tell me where I am going wrong or tell me another way to access the public key

View 1 RepliesI 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.
I want to create a digital signature, for my product, for creating the digital sigmature i want digital certificate. I came to know there are lot of third party available for creating digital signature. If any one know can tell some of third party for this.
View 1 RepliesLet'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 web site and a web service and I would like to host them somewhere.
I need to use it mostly for testing and so that a some friends who are developing some applications to use the service have access to it. Also the service is using a MS SQL 2008 database.good free or cheap web hosting service for this.
I don't have any experience in web hosting. Recently I've completed developing my Asp.net website using Visual Studio 2010. The website retrieves financial data from Yahoo! Finance, does analytical calculations in code-behind, stores processed data into several databases, and allows users to analyze the stock market using those data. Currently I need to run some programs in Visual Studio so that new data get downloaded every day.
My problem is that I know nothing about how to do web hosting so I can actually get my website on the Internet. I heard that there are third-party web site hosting services, but do they allow you to upload entire Asp.net web pages with all the databases attached? What if I need to go in there, run some programs, and update some data in the databases, do these web hosting services allow me to do that?
If the answers to the above are yes, what are some good web hosting services that allow you to upload (I don't even know if "upload" is the correct term to use) Asp.Net web pages? By the way, my website is coded in Visual Basic, if it makes any difference.
I am new to WCF. Please tell me what are different WCF Service Hosting techniques..
