  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.
