I have an SSL cert stored in the Web Hosting Folder of the Certificate Store. I cannot seem to be able to access this store from C#. Does anyone know how to do this?
X509Store store = new X509Store("Web Hosting");
store.Open(OpenFlags.ReadOnly);
var t = store.Certificates.GetEnumerator();
while (t.MoveNext())
{
//this is always empty
}
Additional Detail
I need this cert for a gRPC service that I am writing. gRPC requires a certificate for the SSL connection. In the mean time aka development I am using Let's Encrypt to generate the certificate. When the cert was generated the cert was put into the Web Hosting folder of the cert store.
It turns out you can drag and drop the certs to a different location in the cert manager. I relocated the cert to the Personal folder and I was able to access it by:
X509Store store = new X509Store(StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly);
Try removing the space; e.g., try the name as webhosting (no space)
In PowerShell, to display certs in this store location:
dir cert:\localmachine\webhosting

how can i install two certificates (pfx with password) during my setup is installing on pc? I need Two certificates located on personal->certificates because desktop program is used for all users on this pc.
I'm using .net 3.5
Thanks.
This below will extract the Public & Private key from the .PFX file and parse it into an X509Certificate2 object (X509Certificate type does not support Private keys and is unable understand V2 & V3 properties). You then pass X509Certificate2 object to the local certificate repository which is currently set to LocalMachine as I'm guessing that's where you want it according to the image you attached.
X509Certificate2 cert = new X509Certificate2(#"C:\key.pfx", "test1234", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet); //Saves in the local machine store - accessible for all users
using (var store = new X509Store(StoreName.My, StoreLocation.LocalMachine))
{
store.Open(OpenFlags.ReadWrite); //Set to Write - You need Admin Permissions
store.Add(cert); //Add Private Cert to Store
}
I recommend that you read this post by Paul Stovell before diving head first as permissions could be nightmare especially within a domain environment (Active Directory).
I am kind of new to certificates and all that stuff.
I have a web application that sends a https request by iframe (it has to be https due to the application itself is also https) to a .NET application running on the client which has an HttpListener listening on https://localhost:[port] so the client app can receive a "do something now" from a browser click.
When I install the client app, I install the *.crt file to the Root-Store and bind it to our port:
X509Certificate2 certificateFromCrtFile = new X509Certificate2(X509Certificate2.CreateFromCertFile(crtPath));
X509Store rootStore = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
rootStore.Open(OpenFlags.ReadWrite);
rootStore.Add(certificateFromCrtFile);
rootStore.Close();
string crtThumbprint = certificateFromCrtFile.Thumbprint;
string netshParams = string.Format("http add sslcert ipport=0.0.0.0:[port] certhash={0} appid={{{1}}}", crtThumbprint, Guid.NewGuid());
Utilities.StartProcess("netsh.exe", Environment.SystemDirectory, netshParams, true, true);
Now, before that, I have to install the certificate also in the personal store because my "server" in that case is the HttpListener on the same client.
Okay, so I could do it the following way:
X509Certificate2 certificateFromPfxFile = new X509Certificate2(pfxPath, "pwd");
X509Store personalStore = new X509Store(StoreName.My, StoreLocation.LocalMachine);
personalStore.Open(OpenFlags.ReadWrite);
personalStore.Add(certificateFromPfxFile);
personalStore.Close();
In this case I have to write the *.pfx password in clear text in code.
And if I understood correctly, with this password you can easily get the private key, right?
When storing in PFX the private key is encrypted with your password. So when you attempt to install it to a personal store to indicate your ownership of this certificate, you have to present the password. That's mandate.
The trusted root authority is different, as you don't own the certificates. You just install the crt files to say that you trust whoever owns them.
I'm trying to get the list of certificates from cert store. This is the code I'm using from this post Get list of certificates from the certificate store in C#:
X509Store store = new X509Store(StoreName.My);
store.Open(OpenFlags.ReadOnly);
foreach (X509Certificate2 mCert in store.Certificates)
{
// TODO
}
When I run this code from Test Explorer is finding all available certificates, but when I run it on my MVC application is not returning any certificate.
I'm running VS 2013 as administrator.
Could you please address me what I'm doing wrong?
EDIT:
When I'm running the code on IIS Express I'm getting the list of certificates, but when I run it on Local IIS I'm not getting any results.
Regards,
Most of the time, you want to check the machine store certs, not the ones for your current user. To do that:
X509Store store = new X509Store(StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
foreach (X509Certificate2 certificate in store.Certificates)
{
// TODO
}
This gives you a consistent list, regardless of the IIS user.
If you're attempting to accept certificates from a user, IIS needs to be correctly configured to use HTTPS and accept SSL from the client. You won't be able to go from IIS Express and, let's say, IIS 8.0 without making a few changes in your code.
Check out the top rated answer in How do I get the X509Certificate sent from the client in web service? for the IIS code.
For IIS Express, you can't configure the SSL settings so if you want to pseudo-grab x509 attributes you can do so from the local store. It looks like that's what you're doing right now, which won't work on your local IIS because ApplicationPoolIdentity isn't privileged to access the certificate store.
May be you can try this.
X509Store store = new X509Store(StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly);
foreach (X509Certificate2 mCert in store.Certificates)
{
// TODO
}
You can iterate the store location and the certifications that exist on your computer by using the example provided on this link X509Store Class
I have a console application running on an Azure cloud service VM that need getting a management certificate.
My certificate is loaded on SETTINGS/CERTIFICATE but what should I do next?
I tried something like this:
X509Store certStore = new X509Store(StoreName.My, StoreLocation.LocalMachine);
certStore.Open(OpenFlags.OpenExistingOnly | OpenFlags.ReadOnly);
X509Certificate2Collection certCollection = certStore.Certificates
.Find(X509FindType.FindByThumbprint, certificateThumb, false);
X509Certificate2 certificate = certCollection[0];
Maybe I don't understand how works SETTINGS/CERTIFICATE but I only get an error message saying there are no certificate having this thumbprint.
EDIT: I complete my question.
Is this enough to make a declaration in SETTINGS/CERTIFICATE?
I answer my question.
In fact we have 2 way to use management certificate.
create a publishsetting file with the powershell command get-AzurePublishsettingsFile. The command adds a .cer certificate in management store as well. We just have to deserialize the base 64 certificate found into the file and add it in the credentials
create a certificate with makecert. Load the .cer in the azure management store and the .pfx in the local store from where the client application is installed

I have installed an x509 cert following these directions; http://www.vandyke.com/products/vshell/docs/windows/Use_X.509_Certificates.htm
This istalls it into the trusted root certification authorities store, AuthRoot.
When trying to find the cert;
open the store:X509Store store = new X509Store(StoreName.AuthRoot)
loop through, find one with X thumbprint. This works fine when it is installed into the trusted root cert auth store.
When I try to do the same but install it into the personal store, change opening the store to
X509Store store = new X509Store(StoreName.My) I can not find the cert.
Looking in the certmgr I can see it under personal->certificates.
Is there configuration required in IIS7 for personal cert? Could anyone help explain what I'm missing?
It's StoreName.Root, not StoreName.AuthRoot, for Trusted Root Certification Authorities.
For the personal store, you have to use the X509Store constructor with the StoreLocation parameter to use the Local Computer, Personal store, otherwise you are searching in the Current User, Personal store.
Try:
var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
