23 # This Perl script creates a fresh ca-bundle.crt file for use with libcurl.
24 # It downloads certdata.txt from Mozilla's source tree (see URL below),
25 # then parses certdata.txt and extracts CA Root Certificates into PEM format.
26 # These are then processed with the OpenSSL commandline tool to produce the
27 # final ca-bundle.crt file.
28 # The script is based on the parse-certs script written by Roland Krikava.
29 # This Perl script works on almost any platform since its only external
30 # dependency is the OpenSSL commandline tool for optional text listing.
31 # Hacked by Guenter Knauf.
