Use a Custom Set of Trusted Root Certificates

See more Certificates Examples

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

bool success = false;

// 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..
success = zip.OpenZip("qa_data/certs/thawte-roots.zip");
if (success == false) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

Chilkat.ZipEntry entry = new Chilkat.ZipEntry();
string pemStr;
Chilkat.Cert cert = new Chilkat.Cert();

string pattern = "*.pem";
bool bHasMoreEntries = zip.EntryMatching(pattern,entry);
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);

    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();
