利用C#檢測證書是否存在,並安裝證書

C#檢查證書是否存在

X509Store store = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
            store.Open(OpenFlags.MaxAllowed);
            X509Certificate2Collection certs = store.Certificates.Find(X509FindType.FindBySubjectName, "SRCA", false);
            if (certs.Count == 0 || certs[0].NotAfter < DateTime.Now)
            {
                Console.WriteLine("需要創建證書");
            }

安裝證書:

using System.Security.Cryptography.X509Certificates;

 

MessageBox.Show("開始");

 

//添加個人證書

X509Certificate2 certificate = new X509Certificate2(Application.StartupPath + \\cert.pfx","證書密碼");
X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadWrite);
store.Remove(certificate);   //可省略
store.Add(certificate);
store.Close();


 

//安裝CA的根證書到受信任根證書頒發機構
certificate = new X509Certificate2(Application.StartupPath + "\\CA.cer");
store = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadWrite);
store.Remove(certificate);   //可省略
store.Add(certificate);
store.Close();

           
MessageBox.Show("結束");
