(JavaScript) Use a Custom Set of Trusted Root Certificates

Demonstrates how to build a set of trusted root certificates to be used globally by all Chilkat classes.

Note: This example requires Chilkat v11.0.0 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var trustedRoots = new CkTrustedRoots();

//  Indicate that we will NOT trust any pre-installed certificates on the system.
trustedRoots.TrustSystemCaRoots = false;

// Thawte is a certificate authority that provides a .zip download of their
// root CA certificates:  https://www.thawte.com/roots/index.html
// The direct download link is: https://www.verisign.com/support/thawte-roots.zip
// Note: The above URLs are valid at the time of writing this example (29-May-2015).

// Assuming the .zip has already been downloaded, open it and load each .pem file into
// our trusted roots object.
var zip = new CkZip();

// Open a .zip containing PEM files, among other things..
success = zip.OpenZip("qa_data/certs/thawte-roots.zip");
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

var entry = new CkZipEntry();
var pemStr;
var cert = new CkCert();

var pattern = "*.pem";
var bHasMoreEntries = zip.EntryMatching(pattern,entry);
while (bHasMoreEntries == true) {

    console.log("Entry: " + entry.FileName);

    // Get the PEM of the CA cert:
    pemStr = entry.UnzipToString(0,"utf-8");

    // Load it into a certificate object:
    success = cert.LoadPem(pemStr);
    if (success !== true) {
        console.log(cert.LastErrorText);
    }

    // Add it to the trusted roots.
    trustedRoots.AddCert(cert);

    bHasMoreEntries = entry.GetNextMatch(pattern);
}

//  Activate the trusted roots globally for all Chilkat objects.
//  This call really shouldn't fail, so we're not checking the return value.
success = trustedRoots.Activate();
