# 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 writtten by Roland Krikava.
# This Perl script works on almost any platform since its only external
# dependency is the OpenSSL commandline tool.
# Hacked by Guenter Knauf.

## $crt -- Bundle of CA Root Certificates

## Converted at: $currentdate
##
## This is a bundle of X.509 certificates of public Certificate Authorities
## (CA). These were automatically extracted from Mozilla's root certificates
## file (certdata.txt). This file can be found in the mozilla source tree:
## '/mozilla/security/nss/lib/ckfw/builtins/certdata.txt'
##
## It contains the certificates in both plain text and PEM format
## and therefore can be directly used with curl / libcurl, or with an
## Apache+mod_ssl webserver for SSL client authentication.
## Just configure this file as the SSLCACertificateFile.
