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.
