  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.
