69 Adds a key to the keytab. Options that are not specified will be
70 prompted for. This requires that you know the password or the hex key of the
71 principal to add; if what you really want is to add a new principal to
72 the keytab, you should consider the
74 command, which talks to the kadmin server.

80 Update one or several keys to new versions. By default, use the admin
81 server for the realm of a keytab entry. Otherwise it will use the
