 OpenDNSSEC is a complete DNSSEC zone signing system which is very
 easy to use with stability and security in mind. There are a lot of
 details in signing zone files with DNSSEC and OpenDNSSEC covers most
 of it.
 .
 This package contains the OpenDNSSEC Signer Engine. The task of the
 signer engine is to schedule signing operation on DNS zones. Taking
 input from the KASP, it will automatically sign zones and keep their
 signatures up-to-date.
