+.SH SYNOPSIS

+[\fB\-e\fP \fIkeysalts\fP]
+.SH DESCRIPTION
+.sp
+k5srvutil allows an administrator to list keys currently in
+a keytab, to obtain new keys for a principal currently in a keytab,
+or to delete non\-current keys from a keytab.
+.sp
+\fIoperation\fP must be one of the following:
+.INDENT 0.0
+.TP
+.B \fBlist\fP
+Lists the keys in a keytab, showing version number and principal
+name.
+.TP
+.B \fBchange\fP
+Uses the kadmin protocol to update the keys in the Kerberos
+database to new randomly\-generated keys, and updates the keys in
+the keytab to match. If a key\(aqs version number doesn\(aqt match the
+version number stored in the Kerberos server\(aqs database, then the
+operation will fail. If the \fB\-i\fP flag is given, k5srvutil will
+prompt for confirmation before changing each key. If the \fB\-k\fP
+option is given, the old and new keys will be displayed.
+Ordinarily, keys will be generated with the default encryption
+types and key salts. This can be overridden with the \fB\-e\fP
+option. Old keys are retained in the keytab so that existing
+tickets continue to work, but \fBdelold\fP should be used after
+such tickets expire, to prevent attacks against the old keys.
+.TP
+.B \fBdelold\fP
+Deletes keys that are not the most recent version from the keytab.
+This operation should be used some time after a change operation
+to remove old keys, after existing tickets issued for the service
+have expired. If the \fB\-i\fP flag is given, then k5srvutil will
+prompt for confirmation for each principal.
+.TP
+.B \fBdelete\fP
+Deletes particular keys in the keytab, interactively prompting for
+each key.
+.UNINDENT
+.sp
+In all cases, the default keytab is used unless this is overridden by
+the \fB\-f\fP option.
+.sp
+k5srvutil uses the \fIkadmin(1)\fP program to edit the keytab in
+place.
