NAME
     ktutil -- manage Kerberos keytabs

SYNOPSIS
     ktutil [-k keytab | --keytab=keytab] [-v | --verbose] [--version]
            [-h | --help] command [args]

DESCRIPTION
     ktutil is a program for managing keytabs.  Supported options:

     -v, --verbose
             Verbose output.

     command can be one of the following:

     add [-p principal] [--principal=principal] [-V kvno] [--kvno=kvno] [-e
                 enctype] [--enctype=enctype] [-w password]
                 [--password=password] [-r] [--random] [-s] [--no-salt] [-H]
                 [--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 get command, which talks to the kadmin server.

     change [-r realm] [--realm=realm] [--a host] [--admin-server=host] [--s
                 port] [--server-port=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.

                 If no principals are given, all the ones in the keytab are
                 updated.

     copy keytab-src keytab-dest
                 Copies all the entries from keytab-src to keytab-dest.

     get [-p admin principal] [--principal=admin principal] [-e enctype]
                 [--enctypes=enctype] [-r realm] [--realm=realm] [-a admin
                 server] [--admin-server=admin server] [-s server port]
                 [--server-port=server port] principal ...
                 For each principal, generate a new key for it (creating it if
                 it doesn't already exist), and put that key in the keytab.

                 If no realm is specified, the realm to operate on is taken
                 from the first principal.

     list [--keys] [--timestamp]
                 List the keys stored in the keytab.

     remove [-p principal] [--principal=principal] [-V -kvno] [--kvno=kvno]
                 [-e -enctype] [--enctype=enctype]
                 Removes the specified key or keys. Not specifying a kvno
                 removes keys with any version number. Not specifying an
                 enctype removes keys of any type.

     rename from-principal to-principal
                 Renames all entries in the keytab that match the
                 from-principal to to-principal.

     purge [--age=age]
                 Removes all old versions of a key for which there is a newer
                 version that is at least age (default one week) old.
