(C#) Use HTTPS Client Certificate from .cer and .key FilesDemonstrates how to load a cert + private key from .cer and .key (base64) files and use it for mutual TLS authentication (client-side certificate).
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Http http = new Chilkat.Http(); Chilkat.Cert cert = new Chilkat.Cert(); Chilkat.PrivateKey privKey = new Chilkat.PrivateKey(); // Load any type of certificate (.cer, .p7b, .pem, etc.) by calling LoadFromFile. bool success = cert.LoadFromFile("qa_data/certs/sample_cert_a.cer"); if (success != true) { Debug.WriteLine(cert.LastErrorText); return; } // Load the private key. Chilkat.BinData bd = new Chilkat.BinData(); success = bd.LoadFile("qa_data/certs/sample_key_a.key"); success = privKey.LoadAnyFormat(bd,"privateKeyPasswordIfNecessary"); if (success != true) { Debug.WriteLine(privKey.LastErrorText); return; } // Associate the private key with the cert. success = cert.SetPrivateKey(privKey); if (success != true) { Debug.WriteLine(cert.LastErrorText); return; } // Set the certificate to be used for mutual TLS authentication // (i.e. sets the client-side certificate for two-way TLS authentication) success = http.SetSslClientCert(cert); if (success != true) { Debug.WriteLine(http.LastErrorText); return; } // At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS // connection will automatically use it if the server demands a client-side cert. |
