Digital Certificates For Authentication And Access?

View 3 RepliesUse Digital Certificates In Program Application?
Jun 22, 2009Here is my issue/question. I am relatively new to VB.Net programming, and I have been assigned the task of creating an application that will go out to a Secure web site and download a file. My first issue is it best to do this using a Windows form, ASP.Net or what. My second and main question is how do I authenticated to the secure web site in .net code?
Upon connecting to the secure web site it asks me for a certificate, which at the moment I have to manually present, however we would like to automate this. Then after it authenticates I have to go a few more pages in before i get to the file that needs to be downloaded.Although this file changes daily it has the same key tag so I can hardcode that into the download application. I just need to figure out how to programically authenticate to the site with .Net
.net - Call Web Service Using Client Certificates / Mutual Authentication?
Mar 23, 2012I'm building a web service client using vb .net. The web service is secured with ssl, basic authentication and also requires client certificates. So I created a web reference in Visual Studio and provided the credentials:
Dim cred As New System.Net.NetworkCredential("usr", "passwd")
Dim proxy As New SimpleFromLocal.simple
proxy.Credentials = cred
Console.WriteLine(proxy.helloWorld())
This works as expected, as long as I turn off mutual authentication on the server side.I added a client certificate like this:
Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(certFile)proxy.ClientCertificates.Add(cert)
The certificate is loaded, but the web service call fails. I could post the exception, but it is in german, which is an issue on its own. It basically says: Authentication failed, because the remote site closed the connection.I tried debugging the ssl handshake on the server side and it looks like the client certificate is not transmitted.So what am I missing here? Is it required to install the client certificate on the local machine?Edit: The error thrown:

Java - Using Certificates In A Client-application Consuming A Web Service
Sep 16, 2010I am implementing a VB.NET desktop application which consumes a web service.
The web service implemented in Java and I currently using Tomcat on my localhost to host the web service.
The web service requires secure communication with the client and so I have followed instructions that outlined how to use Java's keytool.exe to create two .jks keystores (one for the client and one for the server) and then create two .cer certificates (one for the client and one for the server)
I have placed the keystores and certificates generate into the directory where the web service is expecting them (according to the instructions)
I have installed the certificates into TrustedPeople and have attempted to use the certificate by setting the ClientCredentials.ClientCertificates property like this:
myServiceProxy.ClientCredentials.ClientCertificate.SetCertificate(storeLocation.CurrentUser, StoreName.TrustedPeople, X509FindType.FindByIssuerName, "name")
I keep getting the following error message when I try to call any method:
An error was discovered processing the <wsse:Security> header
My problem is that I don't know how to use this in the VB.NET client application that is consuming the web service. I could be doing this completely wrong.

View 9 RepliesManaging Form's Code In .net?
Sep 24, 2011Whats the best way to organize code responsible for Form's content.In my case, there is a DataGridView and list, next to it, with a few options available (projects, managers, employees, etc...). Choosing any list's element fills DataGrid with proper data from database.Now, GridFill functions + handling of all add/delete/edit buttons of each list element gives quite a code in the Form's source, which bothers me a bit. How to split it then to avoid problems in the future? While googling, I've seen some advices to use partial classes, modules or just classes. Moving all functions relating the Projects, Managers, ... , to own separate class sounds like a nice idea but then comes the question how to pass all necessary data to the class functions.

Managing Multiple Subroutines?
Feb 25, 2009have been writing code to replace an old Fortran program. The Fortran program had very organized subroutines which could be called from anywhere in the project. Most of these were relatively small and left a small, easily followed main routine. I'm converting over to VB.net and when I write the subroutines they are all on the same form. Wading through 50-100 subroutines on one form is going to be messy.

View 3 Replies.net - Managing Connection To Database In An Asp.net Application?
Mar 17, 2009what would be the best way to manage a connection to a database in asp.net.My application is built using an N-Tier architecture.The DAL consists of static classes with methods such as
Public Shared Sub Delete( _
ByVal connection As MyConnectionClass, _
ByVal contact_id As Integer, _
ByVal contact_timestamp As Date _
[code]....
The point to note here, is that I pass the connection to the DAL from the BLL.Should I create the connections in the MasterPage, store it in an object, then pass it to my business objects as I create them (the thing I'm trying to avoid)Should I create a connection using a static class and calling a method like CreateConnection on it, from the constructor of my business objects (Something I'd like, but I don't want to have a connection per object, I'd like it to be shared for all instances of my objects, but since asp.net is multi-threaded, a static class doesn't make sense to store connections) the solution should also work well in a Windows Forms environment (So no connection storing in session, and retrieving it with a static method in a class, for the current context)?
