.\" generated by cd2nroff 0.1 from mk-ca-bundle.md .TH mk-ca-bundle 1 "March 22 2024" mk-ca-bundle .SH NAME mk\-ca\-bundle \- convert Mozilla\(aqs certificate bundle to PEM format .SH SYNOPSIS mk\-ca\-bundle [options] \fI[outputfile]\fP .SH DESCRIPTION The mk\-ca\-bundle tool downloads the \fIcertdata.txt\fP file from Mozilla\(aqs source tree over HTTPS, then parses \fIcertdata.txt\fP 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 command line tool to produce the final ca\-bundle file. The default \fIoutputfile\fP name is \fBca\-bundle.crt\fP. By setting it to \(aq\-\(aq (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 and others. .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 \fIcertdata.txt\fP 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 certificates data from. .IP -f force rebuild even if \fIcertdata.txt\fP 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 \fIcertdata.txt\fP .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 \fIcertdata.txt\fP (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 (\fISERVER_AUTH:TRUSTED_DELEGATOR\fP). Valid purposes are: \fIALL\fP, \fIDIGITAL_SIGNATURE\fP, \fINON_REPUDIATION\fP, \fIKEY_ENCIPHERMENT\fP, \fIDATA_ENCIPHERMENT\fP, \fIKEY_AGREEMENT\fP, \fIKEY_CERT_SIGN\fP, \fICRL_SIGN\fP, \fISERVER_AUTH\fP (default), \fICLIENT_AUTH\fP, \fICODE_SIGNING\fP, \fIEMAIL_PROTECTION\fP, \fIIPSEC_END_SYSTEM\fP, \fIIPSEC_TUNNEL\fP, \fIIPSEC_USER\fP, \fITIME_STAMPING\fP, \fISTEP_UP_APPROVED\fP Valid trust levels are: \fIALL\fP, \fITRUSTED_DELEGATOR\fP (default), \fINOT_TRUSTED\fP, \fIMUST_VERIFY_TRUST\fP, \fITRUSTED\fP .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. Valid algorithms are: ALL, NONE, MD5 (default), SHA1, SHA256, SHA384, SHA512 .IP -u unlink (remove) \fIcertdata.txt\fP after processing .IP -v be verbose and print out processed certificate authorities .SH EXIT STATUS Returns 0 on success. Returns 1 if it fails to download data. .SH FILE FORMAT The file format used by Mozilla for this trust information is documented here: .nf https://p11-glue.freedesktop.org/doc/storing-trust-policy/storing-trust-existing.html .fi .SH SEE ALSO .BR curl (1)
