Zig Requires Chilkat v11.0.0+

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. Zig

    // See Global Unlock Sample for sample code.

    //  Indicate that we will NOT trust any pre-installed certificates on the system.

    // Thawte is a certificate authority that provides a .zip download of their
    // root CA certificates:  https://www.thawte.com/roots/index.html

    // Note: The above URLs are valid at the time of writing this example (29-May-2015).
