| .TH mk-ca-bundle 1 "24 Oct 2016" "version 1.27" "mk-ca-bundle manual" |
| .SH NAME |
| mk-ca-bundle \- convert mozilla's certdata.txt to PEM format |
| .SH SYNOPSIS |
| mk-ca-bundle [options] |
| .I [outputfile] |
| .SH DESCRIPTION |
| The mk-ca-bundle tool downloads the certdata.txt file from Mozilla's source |
| tree over HTTPS, then parses certdata.txt and extracts certificates into PEM |
| format. By default, only CA root certificates trusted to issue SSL server |
| authentication certificates are extracted. These are then processed with the |
| OpenSSL commandline tool to produce the final ca-bundle file. |
| |
| The default \fIoutputfile\fP name is \fBca-bundle.crt\fP. By setting it to '-' |
| (a single dash) you will get the output sent to STDOUT instead of a file. |
| |
| The PEM format this scripts uses for output makes the result readily available |
| for use by just about all OpenSSL or GnuTLS powered applications, such as |
| curl, wget and more. |
| .SH OPTIONS |
| The following options are supported: |
| .IP -b |
| backup an existing version of \fIoutputfilename\fP |
| .IP "-d [name]" |
| specify which Mozilla tree to pull certdata.txt from (or a custom URL). Valid |
| names are: aurora, beta, central, mozilla, nss, release (default). They are |
| shortcuts for which source tree to get the cert data from. |
| .IP -f |
| force rebuild even if certdata.txt is current (Added in version 1.17) |
| .IP -i |
| print version info about used modules |
| .IP -k |
| Allow insecure data transfer. By default (since 1.27) this command will fail |
| if the HTTPS transfer fails. This overrides that decision (and opens for |
| man-in-the-middle attacks). |
| .IP -l |
| print license info about certdata.txt |
| .IP -m |
| (Added in 1.26) Include meta data comments in the output. The meta data is |
| specific information about each certificate that is stored in the original |
| file as comments and using this option will make those comments get passed on |
| to the output file. The meta data is not parsed in any way by mk-ca-bundle. |
| .IP -n |
| no download of certdata.txt (to use existing) |
| .IP "-p [purposes]:[levels]" |
| list of Mozilla trust purposes and levels for certificates to include in output. |
| Takes the form of a comma separated list of purposes, a colon, and a comma |
| separated list of levels. The default is to include all certificates trusted |
| to issue SSL Server certificates (SERVER_AUTH:TRUSTED_DELEGATOR). |
| |
| (Added in version 1.21, Perl only) |
| |
| Valid purposes are: |
| .RS |
| ALL, DIGITAL_SIGNATURE, NON_REPUDIATION, KEY_ENCIPHERMENT, |
| DATA_ENCIPHERMENT, KEY_AGREEMENT, KEY_CERT_SIGN, CRL_SIGN, |
| SERVER_AUTH (default), CLIENT_AUTH, CODE_SIGNING, EMAIL_PROTECTION, |
| IPSEC_END_SYSTEM, IPSEC_TUNNEL, IPSEC_USER, TIME_STAMPING, STEP_UP_APPROVED |
| .RE |
| .IP |
| Valid trust levels are: |
| .RS |
| ALL, TRUSTED_DELEGATOR (default), NOT_TRUSTED, MUST_VERIFY_TRUST, TRUSTED |
| .RE |
| .IP -q |
| be really quiet (no progress output at all) |
| .IP -t |
| include plain text listing of certificates |
| .IP "-s [algorithms]" |
| comma separated list of signature algorithms with which to hash/fingerprint |
| each certificate and output when run in plain text mode. |
| |
| (Added in version 1.21, Perl only) |
| |
| Valid algorithms are: |
| .RS |
| ALL, NONE, MD5 (default), SHA1, SHA256, SHA384, SHA512 |
| .RE |
| .IP -u |
| unlink (remove) certdata.txt after processing |
| .IP -v |
| be verbose and print out processed CAs |
| .SH EXIT STATUS |
| Returns 0 on success. Returns 1 if it fails to download data. |
| .SH CERTDATA FORMAT |
| The file format used by Mozilla for this trust information seems to be documented here: |
| .nf |
| http://p11-glue.freedesktop.org/doc/storing-trust-policy/storing-trust-existing.html |
| .fi |
| .SH SEE ALSO |
| .BR curl (1) |
| .SH HISTORY |
| \fBmk-ca-bundle\fP is a command line tool that is shipped as part of every |
| curl and libcurl release (see https://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 \&<jschauma@netmeister.org>. |
