NAME

       trust - Tool for operating on the trust policy store

SYNOPSIS

       trust list

       trust extract --filter=<what> --format=<type> /path/to/destination

       trust anchor /path/to/certificate.crt

       trust dump

DESCRIPTION

       trust is a command line tool to examine and modify the shared trust policy store.

       See the various sub commands below. The following global options can be used:

       -v, --verbose
           Run in verbose mode with debug output.

       -q, --quiet
           Run in quiet mode without warning or failure messages.

LIST

       List trust policy store items.

           $ trust list

       List information about the various items in the trust policy store. Each item is listed
       with it's PKCS#11 URI and some descriptive information.

       You can specify the following options to control what to list.

       --filter=<what>
           Specifies what certificates to extract. You can specify the following values:

           ca-anchors
               Certificate anchors

           trust-policy
               Anchors and blacklist (default)

           blacklist
               Blacklisted certificates

           certificates
               All certificates

           pkcs11:object=xx
               A PKCS#11 URI to filter with

           If an output format is chosen that cannot support type what has been specified by the
           filter, a message will be printed.

           None of the available formats support storage of blacklist entries that do not contain
           a full certificate. Thus any certificates blacklisted by their issuer and serial
           number alone, are not included in the extracted blacklist.

       --purpose=<usage>
           Limit to certificates usable for the given purpose You can specify one of the
           following values:

           server-auth
               For authenticating servers

           client-auth
               For authenticating clients

           email
               For email protection

           code-signing
               For authenticated signed code

           1.2.3.4.5...
               An arbitrary purpose OID

ANCHOR

       Store or remove trust anchors.

           $ trust anchor /path/to/certificate.crt
           $ trust anchor --remove /path/to/certificate.crt
           $ trust anchor --remove "pkcs11:id=%AA%BB%CC%DD%EE;type=cert"

       Store or remove trust anchors in the trust policy store. These are usually root
       certificate authorities.

       Specify either the --store or --remove operations. If no operation is specified then
       --store is assumed.

       When storing, one or more certificate files are expected on the command line. These are
       stored as anchors, unless they are already present.

       When removing an anchor, either specify certificate files or PKCS#11 URI's on the command
       line. Matching anchors will be removed.

       It may be that this command needs to be run as root in order to modify the system trust
       policy store, if no user specific store is available.

       You can specify the following options.

       --remove
           Remove one or more anchors from the trust policy store. Specify certificate files or
           PKCS#11 URI's on the command line.

       --store
           Store one or more anchors to the trust policy store. Specify certificate files on the
           command line.

EXTRACT

       Extract trust policy from the shared trust policy store.

           $ trust extract --format=x509-directory --filter=ca-anchors /path/to/directory

       You can specify the following options to control what to extract. The --filter and
       --format arguments should be specified. By default this command will not overwrite the
       destination file or directory.

       --comment
           Add identifying comments to PEM bundle output files before each certificate.

       --filter=<what>
           Specifies what certificates to extract. You can specify the following values:

           ca-anchors
               Certificate anchors (default)

           trust-policy
               Anchors and blacklist

           blacklist
               Blacklisted certificates

           certificates
               All certificates

           pkcs11:object=xx
               A PKCS#11 URI

           If an output format is chosen that cannot support type what has been specified by the
           filter, a message will be printed.

           None of the available formats support storage of blacklist entries that do not contain
           a full certificate. Thus any certificates blacklisted by their issuer and serial
           number alone, are not included in the extracted blacklist.

       --format=<type>
           The format of the destination file or directory. You can specify one of the following
           values:

           x509-file
               DER X.509 certificate file

           x509-directory
               directory of X.509 certificates

           pem-bundle
               File containing one or more certificate PEM blocks

           pem-directory
               Directory of PEM files each containing one certificate

           pem-directory-hash

       --purpose=<usage>
           Limit to certificates usable for the given purpose You can specify one of the
           following values:

           server-auth
               For authenticating servers

EXTRACT COMPAT

       Extract compatibility trust certificate bundles.

           $ trust extract-compat

       OpenSSL, Java and some versions of GnuTLS cannot currently read trust information directly
       from the trust policy store. This command extracts trust information such as certificate
       anchors for use by these libraries.

       What this command does, and where it extracts the files is distribution or site specific.
       Packagers or administrators are expected customize this command.

DUMP

       Dump PKCS#11 items in the various tokens.

           $ trust dump

       Dump information about the various PKCS#11 items in the tokens. Each item is dumped with
       it's PKCS#11 URI and information in the .p11-kit persistence format.

       You can specify the following options to control what to dump.

       --filter=<what>
           Specifies what certificates to extract. You can specify the following values:

           all
               All objects. This is the default

           pkcs11:object=xx
               A PKCS#11 URI to filter with
