How to programmatically install a certificate using C#

Question

my school webpages have selftrusted certificate(you must install it manually) and I wanted create program that will install a certificate.cer (from visual studio resources) to Local user -"Trusted root certificate authority" after i click on a button.Do you know how to code it in Visual C#?

Answer 1

To add the certificate to the trusted root store for the current user programmatically, use the X509Store and X509Certificate2 classes. For example:

string file; // Contains name of certificate file
X509Store store = new X509Store(StoreName.Root, StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadWrite);
store.Add(new X509Certificate2(X509Certificate2.CreateFromCertFile(file)));
store.Close();

Another option is the Certificate Manager command line (certmgr.exe) tool, specifically:

certmgr /add cert.cer /s Root

where "cert.cer" is your certificate. This imports it into the trusted root store for the current user. However, certmgr.exe is part of Visual Studio and the Windows SDK and may not be freely distributable.
