mk-ca-bundle(1) General Commands Manual mk-ca-bundle(1)
mk-ca-bundle - convert Mozilla's certificate bundle to PEM format
mk-ca-bundle [options] [output]
This tool downloads the certdata.txt file from Mozilla's source
tree over HTTPS, then parses it and extracts the included
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 command line tool to produce the final ca-bundle output
file.
The default output name is ca-bundle.crt. By setting it to '-' (a
single dash) you 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 and others.
The following options are supported:
-b backup an existing version of output
-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 certificate data from.
-f force rebuild even if certdata.txt is current (Added in
version 1.17)
-i print version info about used modules
-k Allow insecure data transfer. By default (since 1.27) this
command fails if the HTTPS transfer fails. This overrides
that decision (and opens for man-in-the-middle attacks).
-l print license info about certdata.txt
-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 makes those comments get passed on to
the output file. The meta data is not parsed in any way by
mk-ca-bundle.
-n Do not download certdata.txt - use the existing.
-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).
Valid purposes are: 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
Valid trust levels are: ALL, TRUSTED_DELEGATOR (default),
NOT_TRUSTED, MUST_VERIFY_TRUST, TRUSTED
-q be really quiet (no progress output at all)
-t include plain text listing of certificates
-s [algorithms]
A comma separated list of signature algorithms with which
to hash/fingerprint each certificate and output when run in
plain text mode.
Valid algorithms are: ALL, NONE, MD5 (default), SHA1,
SHA256, SHA384, SHA512
-u unlink (remove) certdata.txt after processing
-v be verbose and print out processed certificate authorities
Returns 0 on success. Returns 1 if it fails to download data.
The file format used by Mozilla for this trust information is
documented here:
