It uses the BIND commands for manipulating DNSSEC key metadata: +\fBdnssec\-keygen\fR +and +\fBdnssec\-settime\fR\&. +.PP +DNSSEC policy can be read from a configuration file (default +/etc/dnssec\-policy\&.conf), from which the key parameters, publication and rollover schedule, and desired coverage duration for any given zone can be determined\&. This file may be used to define individual DNSSEC policies on a per\-zone basis, or to set a default policy used for all zones\&. +.PP +When +\fBdnssec\-keymgr\fR +runs, it examines the DNSSEC keys for one or more zones, comparing their timing metadata against the policies for those zones\&. If key settings do not conform to the DNSSEC policy (for example, because the policy has been changed), they are automatically corrected\&. +.PP +A zone policy can specify a duration for which we want to ensure the key correctness (\fBcoverage\fR)\&. It can also specify a rollover period (\fBroll\-period\fR)\&. If policy indicates that a key should roll over before the coverage period ends, then a successor key will automatically be created and added to the end of the key series\&. +.PP +If zones are specified on the command line, +\fBdnssec\-keymgr\fR +will examine only those zones\&. If a specified zone does not already have keys in place, then keys will be generated for it according to policy\&. +.PP +If zones are +\fInot\fR +specified on the command line, then +\fBdnssec\-keymgr\fR +will search the key directory (either the current working directory or the directory set by the +\fB\-K\fR +option), and check the keys for all the zones represented in the directory\&. +.PP +It is expected that this tool will be run automatically and unattended (for example, by +\fBcron\fR)\&. +.SH "OPTIONS" +.PP +\-c \fIfile\fR +.RS 4 +If +\fB\-c\fR +is specified, then the DNSSEC policy is read from +\fBfile\fR\&. (If not specified, then the policy is read from +/etc/dnssec\-policy\&.conf; if that file doesn\*(Aqt exist, a built\-in global default policy is used\&.) +.RE +.PP +\-f +.RS 4 +Force: allow updating of key events even if they are already in the past\&. This is not recommended for use with zones in which keys have already been published\&. However, if a set of keys has been generated all of which have publication and activation dates in the past, but the keys have not been published in a zone as yet, then this option can be used to clean them up and turn them into a proper series of keys with appropriate rollover intervals\&. +.RE +.PP +\-g \fIkeygen\-path\fR +.RS 4 +Specifies a path to a +\fBdnssec\-keygen\fR +binary\&. Used for testing\&.

For example, a policy class +\fBnormal\fR +might specify 1024\-bit key sizes, but a class +\fBextra\fR +might specify 2048 bits instead; +\fBextra\fR +would be used for zones that had unusually high security needs\&. +.RE +.sp +.RS 4 +.ie n \{\ +\h'-04'\(bu\h'+03'\c +.\} +.el \{\ +.sp -1 +.IP \(bu 2.3 +.\} +Algorithm policies: (\fBalgorithm\-policy \fR\fB\fIalgorithm\fR\fR\fB { \&.\&.\&. };\fR +) override default per\-algorithm settings\&. For example, by default, RSASHA256 keys use 2048\-bit key sizes for both KSK and ZSK\&.
