利用C#检测证书是否存在,并安装证书

C#检查证书是否存在

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("需要创建证书");
            }

安装证书:

using System.Security.Cryptography.X509Certificates;

 

MessageBox.Show("开始");

 

//添加个人证书

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


 

//安装CA的根证书到受信任根证书颁发机构
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("结束");
