Perl 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. Chilkat2 Perl

use strict;
use warnings;

# This example requires the Chilkat API to have been previously unlocked.
# 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
# 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.
my $zip = Chilkat2::Zip->new;

# Open a .zip containing PEM files, among other things..
