Installing Certificate using C#
-
Hi, I am trying to install a .pfx certificate in personal folder using a C# application. Every thing goes fine and certificate is installed. I can see that certificate in the Personal folder of both Current User and Local machine. But when i try to run my application and use that certificate, it throws exception with the message: The credentials supplied to the package were not recognized Stack Trac at System.Net.SSPIWrapper.AcquireCredentialsHandle(SSPIInterface SecModule, String package, CredentialUse intent, SecureCredential scc)...... But when i import this cert manually, it works just fine. Below is the code i am using for installing the certificate:
Dim cert_personal As X509Certificate2 = Nothing Try cert_personal = New X509Certificate2 cert_personal.Import(Application.StartupPath & "\Chain\Personal.pfx","My Password" , (X509KeyStorageFlags.UserKeySet Or X509KeyStorageFlags.Exportable)) Catch ex As Exception MsgBox(ex.Message) End Try If cert_personal Is Nothing Then Return False End If ''XXXXXXXXXXXXXXXXXXXXXXXX PERSONAL XXXXXXXXXXXXXXXXXXXXXXXXXXXXX Dim store As New X509Store(StoreName.My, StoreLocation.CurrentUser) Try store.Open(OpenFlags.ReadWrite) Dim findVal As String = cert_personal.Thumbprint 'Thumbprint Dim certColl As X509Certificate2Collection = store.Certificates.Find(X509FindType.FindByThumbprint, findVal, False) If certColl.Count <= 0 Then store.Add(cert_personal) End If Catch ex As Exception MsgBox(ex.Message) Finally store.Close() End TryAnd almost same for installing in Local machine. The complete chain is also fine. But the problem is still there. I can't use CertMgr since this cert is from a third party which is not , as per my info, supported by that. Any suggestion, code sample, advice would be highly appreciated. Thanks in advance, Wasif Ehsan.
