##
## Bundle of CA Root Certificates
##
## Generated with Sslurp (https://github.com/EvanDotPro/Sslurp)
##
## This is a bundle of X.509 certificates of public Certificate Authorities.
## These were automatically extracted from Mozilla's root certificates
## file (certdata.txt). This file can be found in the Mozilla source tree:
## /mozilla/source/security/nss/lib/ckfw/builtins/certdata.txt
##
## http://www.mozilla.org/projects/security/certs/policy/
## http://www.mozilla.org/projects/security/pki/nss/
##
## This file contains the certificates in PEM format and therefore
## can be directly used with curl / libcurl / php_curl, or with
## an Apache+mod_ssl webserver for SSL client authentication.
## Just configure this file as the SSLCACertificateFile.
