using System; using System.Net; class Program { static void Main() { // Replace with the actual URL you want to connect to string targetUrl = "https://example.com"; try { // Set the security protocol to TLS 1.2 (compatible with 2012 R2) ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; // Replace with the Cipher Suites you want to use string[] cipherSuites = { "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384", "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256" }; // Set the Cipher Suites ServicePointManager.Expect100Continue = true; ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; // Disable older protocols for enhanced security ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Tls; ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Ssl3; // Set the Cipher Suites ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Ssl2; ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true; // Create a web request HttpWebRequest request = (HttpWebRequest)WebRequest.Create(targetUrl); // Set the Cipher Suites on the request request.CipherSuites = cipherSuites; // Perform the request using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { // Process the response if needed Console.WriteLine("Response Status: " + response.StatusCode); } } catch (Exception ex) { Console.WriteLine("Error: " + ex.Message); } } } The code sets the security protocol to TLS 1.2 and specifies two Cipher Suites ( TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 and TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 ). You should replace these values with the Cipher Suites that you want to use.
