   23: .TH mk-ca-bundle 1 "24 Oct 2016" "version 1.27" "mk-ca-bundle manual"
   24: .SH NAME
   25: mk-ca-bundle \- convert mozilla's certdata.txt to PEM format
   26: .SH SYNOPSIS
   27: mk-ca-bundle [options]
   28: .I [outputfile]
   29: .SH DESCRIPTION
   30: The mk-ca-bundle tool downloads the certdata.txt file from Mozilla's source
   31: tree over HTTPS, then parses certdata.txt and extracts certificates into PEM
   32: format. By default, only CA root certificates trusted to issue SSL server
   33: authentication certificates are extracted. These are then processed with the
   34: OpenSSL commandline tool to produce the final ca-bundle file.
   35: 
   36: The default \fIoutputfile\fP name is \fBca-bundle.crt\fP. By setting it to '-'
   37: (a single dash) you will get the output sent to STDOUT instead of a file.
   38: 
   39: The PEM format this scripts uses for output makes the result readily available
   40: for use by just about all OpenSSL or GnuTLS powered applications, such as
   41: curl, wget and more.
   42: .SH OPTIONS
   43: The following options are supported:
   44: .IP -b
   45: backup an existing version of \fIoutputfilename\fP
   46: .IP "-d [name]"
   47: specify which Mozilla tree to pull certdata.txt from (or a custom URL). Valid
   48: names are: aurora, beta, central, mozilla, nss, release (default). They are
   49: shortcuts for which source tree to get the cert data from.
   50: .IP -f
   51: force rebuild even if certdata.txt is current (Added in version 1.17)
   52: .IP -i
   53: print version info about used modules
   54: .IP -k
   55: Allow insecure data transfer. By default (since 1.27) this command will fail
   56: if the HTTPS transfer fails. This overrides that decision (and opens for
   57: man-in-the-middle attacks).
   58: .IP -l
   59: print license info about certdata.txt
   60: .IP -m
   61: (Added in 1.26) Include meta data comments in the output. The meta data is
   62: specific information about each certificate that is stored in the original
   63: file as comments and using this option will make those comments get passed on
   64: to the output file. The meta data is not parsed in any way by mk-ca-bundle.
   65: .IP -n
   66: no download of certdata.txt (to use existing)
   67: .IP "-p [purposes]:[levels]"
   68: list of Mozilla trust purposes and levels for certificates to include in output.
   69: Takes the form of a comma separated list of purposes, a colon, and a comma
   70: separated list of levels. The default is to include all certificates trusted
   71: to issue SSL Server certificates (SERVER_AUTH:TRUSTED_DELEGATOR).
   72: 
   73: (Added in version 1.21, Perl only)
   74: 
   75: Valid purposes are:
   76: .RS
   77: ALL, DIGITAL_SIGNATURE, NON_REPUDIATION, KEY_ENCIPHERMENT,
   78: DATA_ENCIPHERMENT, KEY_AGREEMENT, KEY_CERT_SIGN, CRL_SIGN,
   79: SERVER_AUTH (default), CLIENT_AUTH, CODE_SIGNING, EMAIL_PROTECTION,
   80: IPSEC_END_SYSTEM, IPSEC_TUNNEL, IPSEC_USER, TIME_STAMPING, STEP_UP_APPROVED
   81: .RE
   82: .IP
   83: Valid trust levels are:
   84: .RS
   85: ALL, TRUSTED_DELEGATOR (default), NOT_TRUSTED, MUST_VERIFY_TRUST, TRUSTED
   86: .RE
   87: .IP -q
   88: be really quiet (no progress output at all)
   89: .IP -t
   90: include plain text listing of certificates
   91: .IP "-s [algorithms]"
   92: comma separated list of signature algorithms with which to hash/fingerprint
   93: each certificate and output when run in plain text mode.
   94: 
   95: (Added in version 1.21, Perl only)
   96: 
   97: Valid algorithms are:
   98: .RS
   99: ALL, NONE, MD5 (default), SHA1, SHA256, SHA384, SHA512
  100: .RE
  101: .IP -u
  102: unlink (remove) certdata.txt after processing
  103: .IP -v
  104: be verbose and print out processed CAs
  105: .SH EXIT STATUS
  106: Returns 0 on success. Returns 1 if it fails to download data.
  107: .SH CERTDATA FORMAT
  108: The file format used by Mozilla for this trust information seems to be documented here:
  109: .nf
  110: https://p11-glue.freedesktop.org/doc/storing-trust-policy/storing-trust-existing.html
  111: .fi
  112: .SH SEE ALSO

  114: .SH HISTORY
  115: \fBmk-ca-bundle\fP is a command line tool that is shipped as part of every
  116: curl and libcurl release (see https://curl.haxx.se/). It was originally based
  117: on the parse-certs script written by Roland Krikava and was later much
  118: improved by Guenter Knauf.  This manual page was initially written by Jan
  119: Schaumann \&<jschauma@netmeister.org>.
