This option is only valid in conjunction with the .Ic rehash command. .It Fl D Ar destdir Specify the DESTDIR (overriding values from the environment). .It Fl d Ar distbase Specify the DISTBASE (overriding values from the environment). .It Fl l When listing installed (trusted or untrusted) certificates, show the full path and distinguished name for each certificate. .It Fl M Ar metalog Specify the path of the METALOG file .Po default: .Pa ${DESTDIR}/METALOG .Pc . This option is only valid in conjunction with the .Ic rehash command. .It Fl n Dry-run mode. Do not actually perform any actions except write the metalog. .It Fl v Verbose mode. Print detailed information about each action taken. .It Fl U Unprivileged mode. Do not attempt to set the ownership of created files. This option is only valid in conjunction with the .Fl M option and the .Ic rehash command. .El .Pp Primary command functions: .Bl -tag -width untrusted .It Ic list List all currently trusted certificates. .It Ic untrusted List all currently untrusted certificates. .It Ic rehash Rebuild the list of trusted certificates by scanning all directories in .Ev TRUSTPATH and all untrusted certificates in .Ev UNTRUSTPATH . A copy of each trusted certificate is placed in .Ev TRUSTDESTDIR and each untrusted certificate in .Ev UNTRUSTDESTDIR . In addition, a bundle containing the trusted certificates is placed in .Ev BUNDLE . .It Ic untrust Add the specified file to the untrusted list. .It Ic trust Remove the specified file from the untrusted list. .El .Sh ENVIRONMENT .Bl -tag -width UNTRUSTDESTDIR .It Ev DESTDIR Absolute path to an alternate destination directory to operate on instead of the file system root, e.g. .Dq Li /tmp/install . .It Ev DISTBASE Additional path component to include when operating on certificate directories. This must start with a slash, e.g. .Dq Li /base . .It Ev LOCALBASE Location for local programs. Defaults to the value of the user.localbase sysctl which is usually .Pa /usr/local . .It Ev TRUSTPATH List of paths to search for trusted certificates. Default: .Pa ${DESTDIR}${DISTBASE}/usr/share/certs/trusted .Pa ${DESTDIR}${LOCALBASE}/share/certs/trusted .Pa ${DESTDIR}${LOCALBASE}/share/certs .It Ev UNTRUSTPATH List of paths to search for untrusted certificates. Default: .Pa ${DESTDIR}${DISTBASE}/usr/share/certs/untrusted .Pa ${DESTDIR}${LOCALBASE}/share/certs/untrusted .It Ev TRUSTDESTDIR Destination directory for symbolic links to trusted certificates. Default: .Pa ${DESTDIR}${DISTBASE}/etc/ssl/certs .It Ev UNTRUSTDESTDIR Destination directory for symbolic links to untrusted certificates. Default: .Pa ${DESTDIR}${DISTBASE}/etc/ssl/untrusted .It Ev BUNDLE File name of bundle to produce. Default: .Pa ${DESTDIR}${DISTBASE}/etc/ssl/cert.pem .El .Sh SEE ALSO .Xr openssl 1 .Sh HISTORY .Nm first appeared in .Fx 12.2 . .Sh AUTHORS .An -nosplit The original shell implementation was written by .An Allan Jude Aq Mt [email protected] .
