Reading SSL Certificate Details In C#

Afterward, choose Certificate and Add.

Afterward, click Add, and it will ask for the following details.

These are actually the stores where the certificates are placed. If we want to access these storage locations, then store location.CurrentUser specifies that I want"My user account" store andStoreName.My specifies to the Personal folder in the recent versions of Windows. Hence, if I want to read the certificates from the Personal folder, then I should use storeName.MY.

Now, as you see, my Personal folder has the following certificate. Now, I want to read the certificate details. To show the details, I have the following snapshot with a Gridview.

Now, here is my code to read the certificate details.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Security.Cryptography.X509Certificates;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace CertificateDetails
{
    public partial class Form1 : Form
    {
        DataTable dt = new DataTable();
        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
            store.Open(OpenFlags.ReadOnly);
            DataColumn dc1 = new DataColumn("Friendly Name", typeof(string));
            DataColumn dc2 = new DataColumn("ThumbPrint", typeof(string));
            DataColumn dc3 = new DataColumn("SerialNumber", typeof(string));
            DataColumn dc4 = new DataColumn("IssuedBy", typeof(string));
            DataColumn dc5 = new DataColumn("ExpiryDate", typeof(string));
            dt.Columns.Add(dc1);
            dt.Columns.Add(dc2);
            dt.Columns.Add(dc3);
            dt.Columns.Add(dc4);
            dt.Columns.Add(dc5);
            foreach (X509Certificate2 mCert in store.Certificates)
            {
                dt.Rows.Add(
                    mCert.FriendlyName,
                    mCert.Thumbprint,
                    mCert.SerialNumber,
                    mCert.Issuer,
                    mCert.GetExpirationDateString()
                );
            }
            dataGridView1.DataSource = dt;
        }
    }
}

Now, run the program and check. It will show the details of the certificate as follows.

Thus, in this way, we can read the certificate details in our Application.
