(Mono C#) 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.

Chilkat for Mono

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

Chilkat.TrustedRoots trustedRoots = new Chilkat.TrustedRoots();

//  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.
Chilkat.Zip zip = new Chilkat.Zip();

// Open a .zip containing PEM files, among other things..
bool success = zip.OpenZip("qa_data/certs/thawte-roots.zip");
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

Chilkat.ZipEntry entry = zip.FirstMatchingEntry("*.pem");
if (zip.LastMethodSuccess != true) {
    Debug.WriteLine("No entries matched.");
    return;
}

Chilkat.ZipEntry nextEntry = null;
string pemStr;

Chilkat.Cert cert = new Chilkat.Cert();

bool bHasMoreEntries = true;
while ((bHasMoreEntries == true)) {

    Debug.WriteLine("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) {
        Debug.WriteLine(cert.LastErrorText);
    }

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

    // The NextMatchingEntry method was added in v9.5.0.50
    nextEntry = entry.NextMatchingEntry("*.pem");
    bHasMoreEntries = entry.LastMethodSuccess;

    entry = nextEntry;
}

//  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();
