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. Go

    success := false

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

    trustedRoots := chilkat.NewTrustedRoots()

    //  Indicate that we will NOT trust any pre-installed certificates on the system.
    trustedRoots.SetTrustSystemCaRoots(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.
    zip := chilkat.NewZip()

    // Open a .zip containing PEM files, among other things..
    success = zip.OpenZip("qa_data/certs/thawte-roots.zip")
    if success == false {
        fmt.Println(zip.LastErrorText())
        trustedRoots.DisposeTrustedRoots()
        zip.DisposeZip()
        return
    }

    entry := chilkat.NewZipEntry()
    var pemStr *string = new(string)
    cert := chilkat.NewCert()

    pattern := "*.pem"
    bHasMoreEntries := zip.EntryMatching(pattern,entry)
    for bHasMoreEntries == true {

        fmt.Println("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 {
            fmt.Println(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()

    trustedRoots.DisposeTrustedRoots()
    zip.DisposeZip()
    entry.DisposeZipEntry()
    cert.DisposeCert()
