53 is a program for managing keytabs.
64 can be one of the following:
65 .Bl -tag -width srvconvert
68 .Op Fl -principal= Ns Ar principal
70 .Op Fl -kvno= Ns Ar kvno
72 .Op Fl -enctype= Ns Ar enctype
74 .Op Fl -password= Ns Ar password
82 Adds a key to the keytab. Options that are not specified will be
83 prompted for. This requires that you know the password or the hex key of the
84 principal to add; if what you really want is to add a new principal to
85 the keytab, you should consider the
87 command, which talks to the kadmin server.
90 .Op Fl -realm= Ns Ar realm
92 .Op Fl -admin-server= Ns Ar host
94 .Op Fl -server-port= Ns Ar port
96 Update one or several keys to new versions. By default, use the admin
97 server for the realm of a keytab entry. Otherwise it will use the
98 values specified by the options.
100 If no principals are given, all the ones in the keytab are updated.
105 Copies all the entries from
110 .Op Fl p Ar admin principal
111 .Op Fl -principal= Ns Ar admin principal
113 .Op Fl -enctypes= Ns Ar enctype
115 .Op Fl -realm= Ns Ar realm
116 .Op Fl a Ar admin server
117 .Op Fl -admin-server= Ns Ar admin server
118 .Op Fl s Ar server port
119 .Op Fl -server-port= Ns Ar server port
124 generate a new key for it (creating it if it doesn't already exist),
125 and put that key in the keytab.
129 is specified, the realm to operate on is taken from the first
135 List the keys stored in the keytab.
137 .Op Fl p Ar principal
138 .Op Fl -principal= Ns Ar principal
140 .Op Fl -kvno= Ns Ar kvno
142 .Op Fl -enctype= Ns Ar enctype
144 Removes the specified key or keys. Not specifying a
146 removes keys with any version number. Not specifying an
148 removes keys of any type.
153 Renames all entries in the keytab that match the
158 .Op Fl -age= Ns Ar age
160 Removes all old versions of a key for which there is a newer version
163 (default one week) old.
