+.Nm
+is a program for managing keytabs.
+Supported options:
+.Bl -tag -width Ds
+.It Fl v , Fl Fl verbose
+Verbose output.
+.El
+.Pp
+.Ar command
+can be one of the following:
+.Bl -tag -width srvconvert
+.It Nm add Oo Fl p Ar principal Oc Oo Fl Fl principal= Ns Ar principal Oc \
+Oo Fl V Ar kvno Oc Oo Fl Fl kvno= Ns Ar kvno Oc Oo Fl e Ar enctype Oc \
+Oo Fl Fl keepold | Fl Fl keepallold | Fl Fl pruneall Oc \
+Oo Fl Fl enctype= Ns Ar enctype Oc Oo Fl w Ar password Oc \
+Oo Fl Fl password= Ns Ar password Oc Oo Fl r Oc Oo Fl Fl random Oc \
+Oo Fl s Oc Oo Fl Fl no-salt Oc Oo Fl H Oc Op Fl Fl hex
+Adds a key to the keytab. Options that are not specified will be
+prompted for. This requires that you know the password or the hex key of the
+principal to add; if what you really want is to add a new principal to
+the keytab, you should consider the
+.Ar get
+command, which talks to the kadmin server.
+.It Nm change Oo Fl r Ar realm Oc Oo Fl Fl realm= Ns Ar realm Oc \
+Oo Fl Fl keepold | Fl Fl keepallold | Fl Fl pruneall Oc \
+Oo Fl Fl enctype= Ns Ar enctype Oc \
+Oo Fl Fl a Ar host Oc Oo Fl Fl admin-server= Ns Ar host Oc \
+Oo Fl Fl s Ar port Oc Op Fl Fl server-port= Ns Ar port
+Update one or several keys to new versions. By default, use the admin
+server for the realm of a keytab entry. Otherwise it will use the
+values specified by the options.
+.Pp
+If no principals are given, all the ones in the keytab are updated.
+.It Nm copy Oo Fl Fl copy-duplicates Oc Ar keytab-src Ar keytab-dest
+Copies all the entries from
+.Ar keytab-src
+to
+.Ar keytab-dest .
+Because entries already in
+.Ar keytab-dest
+are kept, this command functions to merge keytabs.
+Entries for the same principal, key version number, and
+encryption type in the
+.Ar keytab-src
+that are also in the
+.Ar keytab-dest
+will not be copied to the
+.Ar keytab-dest
+unless the
+.Fl Fl copy-duplicates
+option is given.
+.It Nm get Oo Fl p Ar admin principal Oc \
+Oo Fl Fl principal= Ns Ar admin principal Oc Oo Fl e Ar enctype Oc \
+Oo Fl Fl no-create Oc \
+Oo Fl Fl no-change-keys Oc \
+Oo Fl Fl keepold | Fl Fl keepallold | Fl Fl pruneall Oc \
+Oo Fl Fl enctypes= Ns Ar enctype Oc Oo Fl r Ar realm Oc \
+Oo Fl Fl realm= Ns Ar realm Oc Oo Fl a Ar admin server Oc \
+Oo Fl Fl admin-server= Ns Ar admin server Oc Oo Fl s Ar server port Oc \
+Oo Fl Fl server-port= Ns Ar server port Oc Ar principal ...
+.Pp
+For each
+.Ar principal ,
+get a the principal's keys from the KDC via the kadmin protocol,
+creating the principal if it doesn't exist (unless
+.Fl Fl no-create
+is given), and changing its keys to new random keys (unless
+.Fl Fl no-change-keys
+is given).
+.Pp
+If no
+.Ar realm
+is specified, the realm to operate on is taken from the first
+principal.
+.It Nm import Oo JSON-FILE Oc
+Read an array of keytab entries in a JSON file and copy them to
+the keytab.
+Use the
+.Nm list
+command with its
+.Fl Fl json
+option
+and
+.Fl Fl keys
+option to export a keytab.
+.It Nm list Oo Fl Fl keys Oc Op Fl Fl timestamp Oo Op Fl Fl json Oc
+List the keys stored in the keytab.
+Use the
+.Fl Fl json
+and
+.Fl Fl keys
+options to export a keytab as JSON for importing with the
+.Nm import
+command.
+.It Nm remove Oo Fl p Ar principal Oc Oo Fl Fl principal= Ns Ar principal Oc \
+Oo Fl V kvno Oc Oo Fl Fl kvno= Ns Ar kvno Oc Oo Fl e enctype Oc \
+Oo Fl Fl enctype= Ns Ar enctype Oc
+Removes the specified key or keys. Not specifying a
+.Ar kvno
+removes keys with any version number. Not specifying an
+.Ar enctype
+removes keys of any type.
+.It Nm merge Oo Fl Fl copy-duplicates Oc Ar keytab-src Ar keytab-dest
+An alias for the
+.Nm copy
+command.
+.It Nm rename Ar from-principal Ar to-principal
+Renames all entries for the
+.Ar from-principal
+in the keytab
+.Ar from-principal
+to
+.Ar to-principal .
+.It Nm purge Op Fl Fl age= Ns Ar age
+Removes all old versions of a key for which there is a newer version
+that is at least
+.Ar age
+(default one week) old.
+Note that this does not update the KDC database.
+The
+.Xr kadmin 1
+command has a
+.Nm prune
+command that can do this on the KDC side.
+.El
+.Sh ENVIRONMENT
+.Bl -tag -width Ds
+.It Ev KRB5_KTNAME
+Specifies the default keytab.
+.It Ev KRB5_CONFIG
+The file name of
+.Pa krb5.conf ,
+the default being
+.Pa /etc/krb5.conf .
+.El
+.Sh KEYTAB NAMING
+The syntax for the value of the
+.Ql KRB5_KTNAME
+environment variable and
+.Oo Fl k Ar keytab \*(Ba Xo
+.Fl Fl keytab= Ns Ar keytab
+.Xc
+.Oc
+options is
+.Ql TYPE:name
+where the TYPE is one of
+.Ql FILE ,
+.Ql HDBGET ,
+.Ql HDB ,
+or
+.Ql ANY ,
+and the name syntax is specific to the keytab type.
+.Pp
+For the FILE keytab type the name is the path to a file whose
+format is the well-known keytab file format used by MIT Kerberos,
+Heimdal, Java, and others.
+.Pp
+For the HDB and HDBGET keytab types the name syntax is
+.Ql [<path>][:mkey=<path>]
+where the first path is the path to the HDB and the second path
+is the path to the master key file.
+Note that to use the HDB and HDBGET keytab types in a program
+linked with Heimdal libraries one first load the
+.Ql libhdb
+library and then register their keytab methods using
+.Xr krb5_kt_register 3 .
+Note also that
+.Nm ktutil
+does not load and register the HDB and HDBGET keytab types at
+this time.
+.Pp
+The ANY keytab type name syntax is a sequence of other keytab
+names (including their TYPE: prefix) separated by commas.
+Note that there is no escape sequence for commas in keytab names.
