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