cURL Docs Man Page
curl.1 the man page
The mk-ca-bundle tool downloads the certdata.txt file from Mozilla's source tree over HTTP, 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 file.
The default outputfile name is ca-bundle.crt. By setting it to '-' (a single dash) you will get the output sent to STDOUT instead of a file.
The following options are supported:
backup an existing version of outputfilename
force rebuild even if certdata.txt is current (Added in version 1.17)
print version info about used modules
print license info about certdata.txt
no download of certdata.txt (to use existing)
be really quiet (no progress output at all)
include plain text listing of certificates
unlink (remove) certdata.txt after processing
The file format used by Mozilla for this trust information seems to be documented here:
mk-ca-bundle is a command line tool that is shipped as part of every curl and libcurl release (see http://curl.haxx.se/). It was originally based on the parse-certs script written by Roland Krikava and was later much improved by Guenter Knauf. This manual page was initially written by Jan Schaumann <firstname.lastname@example.org>.
