.SH DESCRIPTION
The 
.I dnssec-zkt
command is a wrapper around 
.I dnssec-keygen(8)
to assist in dnssec zone key management.
.PP
In the common usage the command prints out information about
all dnssec (zone) keys found in the given (or predefined default) directory.
It's also possible to specify keyfiles (K*.key) as arguments.
With option
.B \-r
subdirectories will be searched recursively, and all dnssec keys found
will be listed sorted by domain name, key type and generation time.
In that mode the use of the
.B \-p
option may be helpful to find the location of the keyfile in the directory tree.
.PP
Other forms of the command print out keys in a format suitable for
a trusted-key section or as a DNSKEY resource record.
.PP
The command is also useful in dns key management.
It allows key livetime monitoring and status change.

.SH GENERAL OPTIONS
.TP
.BI \-V " view" ", \-\-view=" view
Try to read the default configuration out of a file named
.I dnssec-<view>.conf .
Instead of specifying the \-V or --view option every time,
it's also possible to create a hard or softlink to the
executable file to give it an additional name like 
.I dnssec-zkt-<view> .
.TP
.BI \-c " file" ", \-\-config=" file
Read default values from the specified config file.
Otherwise the default config file is read or build in defaults
will be used.
.TP
.BI \-O " optstr" ", \-\-config-option=" optstr
Set any config file option via the commandline.
Several config file options could be specified at the argument string
but have to be delimited by semicolon (or newline).
.TP
.BI \-l " list"
Print out information solely about domains given in the comma or space separated
list.
Take care of, that every domain name has a trailing dot.
.TP
.BR \-d ", " \-\-directory
Skip directory arguments.
This will be useful in combination with wildcard arguments
to prevent dnsssec-zkt to list all keys found in subdirectories. 
For example "dnssec-zkt -d *" will print out a list of all keys only found in
the current directory.
Maybe it's easier to use "dnssec-zkt ." instead (without -r set).
The option works similar to the \-d option of
.IR ls(1) .
.TP
.BR \-L ", " \-\-left-justify
Print out the domain name left justified.
.TP
.BR \-k ", " \-\-ksk
Select and print key signing keys only (default depends on command mode).
.TP
.BR \-z ", " \-\-zsk
Select and print zone signing keys only (default depends on command mode).
.TP
.BR \-r ", " \-\-recursive
Recursive mode (default is off).
.br
Also settable in the dnssec.conf file (Parameter: Recursive).
.TP
.BR \-p ", " \-\-path
Print pathname in listing mode.
In -C mode, don't create the new key in the same directory as (already existing)
keys with the same label.
.TP
.BR \-a ", " \-\-age
Print age of key in weeks, days, hours, minutes and seconds (default is off).
.br
Also settable in the dnssec.conf file (Parameter: PrintAge).
.TP
.BR \-f ", " \-\-lifetime
Print the key lifetime.
.TP
.BR \-F ", " \-\-setlifetime
Set the key lifetime of all the selected keys.
Use option -k, -z, -l or the file and dir argument for key selection.
.TP
.BR \-e ", " \-\-exptime
Print the key expiration time.
.TP
.BR \-t ", " \-\-time
Print the key generation time (default is on).
.br
Also settable in the dnssec.conf file (Parameter: PrintTime).
.TP
.B \-h
No header or trusted-key section header and trailer in -T mode
.PP

.SH COMMAND OPTIONS
.TP
.BR \-H ", " \-\-help
Print out the online help.
.TP
.BR \-T ", " \-\-list-trustedkeys
List all key signing keys as a
.I named.conf
trusted-key section.
Use
.B \-h
to supress the section header/trailer.
.TP
.BR \-K ", " \-\-list-dnskeys
List the public part of all the keys in DNSKEY resource record format.
Use
.B \-h
to suppress comment lines.
.TP
.BI \-C " zone" ",  \-\-create=" zone
Create a new zone signing key for the given zone.
Add option
.B \-k
to create a key signing key.
The key algorithm and key length will be examined from built-in default values
or from the parameter settings in the
.I dnssec.conf
file.
.br
The keyfile will be created in the current directory if
the
.B \-p
option is specified.
.TP
.BI \-R " keyid" ", \-\-revoke=" keyid
Revoke the key signing key with the given keyid.
A revoked key has bit 8 in the flags filed set (see RFC5011).
The keyid is the numeric keytag with an optionally added zone name separated by a colon.
.TP
.BI \-\-rename=" keyid
Rename the key files of the key with the given keyid
(Look at key file names starting with an lower 'k').
The keyid is the numeric keytag with an optionally added zone name separated by a colon.
.TP
.BI \-\-destroy= keyid
Deletes the key with the given keyid.
The keyid is the numeric keytag with an optionally added zone name separated by a colon.
Beware that this deletes both private and public keyfiles, thus the key is
unrecoverable lost.
.TP
.BI \-P|A|D " keyid," " \-\-published=" keyid, " \-\-active=" keyid, " \-\-depreciated=" keyid
Change the status of the given dnssec key to
published
.RB ( \-P ),
active
.RB ( \-A )
or depreciated
.RB ( \-D ).
The
.I keyid
is the numeric keytag with an optionally added zone name separated by a colon.
Setting the status to "published" or "depreciate" will change the filename
of the private key file to ".published" or ".depreciated" respectivly.
This prevents the usage of the key as a signing key by the use of
.IR dnssec-signzone(8) .
The time of status change will be stored in the 'mtime' field of the corresponding
".key" file.
Key activation via option
.B \-A
will restore the original timestamp and file name (".private").
.TP
.BR \-Z ", " \-\-zone-config
Write all config parameters to stdout.
The output is suitable as a template for the
.I dnssec.conf
file, so the easiest way to create a
.I dnssec.conf
file is to redirect the standard output of the above command.
Pay attention not to overwrite an existing file.
.TP
.BI \-\-ksk-roll-phase[123] " do.ma.in."
Initiate a key signing key rollover of the specified domain.
This feature is currently in experimental status and is mainly for the use
in an hierachical environment.
Use --ksk-rollover for a little more detailed description.
