Use Installed Cert on Windows for TLS Client Authentication

See more HTTP Examples

Demonstrates how to use a certificate that has already been installed on a Windows PC for TLS client authentication. Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    http := chilkat.NewHttp()

    // On Windows, a pre-installed certificate can be loaded in a number of different ways.
    // This example loads by the common name:
    cert := chilkat.NewCert()
    success = cert.LoadByCommonName("My ECA Medium Assurance Identity Certificate")
    if success != true {
        fmt.Println(cert.LastErrorText())
        http.DisposeHttp()
        cert.DisposeCert()
        return
    }

    // Make sure this certificate has a private key available.  
    // It should be a private key such that when the certificate was installed, it was marked as "exportable"
    // so that authorized programs are able to access the private key.
    if cert.HasPrivateKey() != true {
        fmt.Println("A private key is needed for TLS client authentication.")
        fmt.Println("This certificate has no private key.")
        http.DisposeHttp()
        cert.DisposeCert()
        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 {
        fmt.Println(http.LastErrorText())
        http.DisposeHttp()
        cert.DisposeCert()
        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.

    http.DisposeHttp()
    cert.DisposeCert()
