dnssec-makekeyset - DNSSEC zone signing tool
dnssec-makekeyset [ -a ] [ -s start-time ] [ -e end-time ] [ -h ] [
-p ] [ -r randomdev ] [ -tttl ] [ -v level ] key...
dnssec-makekeyset generates a key set from one or more keys created by
dnssec-keygen. It creates a file containing a KEY record for each key,
and self-signs the key set with each zone key. The output file is of
the form keyset-nnnn., where nnnn is the zone name.
-a Verify all generated signatures.
Specify the date and time when the generated SIG records become
valid. This can be either an absolute or relative time. An abso-
lute start time is indicated by a number in YYYYMMDDHHMMSS nota-
tion; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000. A
relative start time is indicated by +N, which is N seconds from
the current time. If no start-time is specified, the current
time is used.
Specify the date and time when the generated SIG records expire.
As with start-time, an absolute time is indicated in YYYYMMDDHH-
MMSS notation. A time relative to the start time is indicated
with +N, which is N seconds from the start time. A time realtive
to the current time is indicated with now+N. If no end-time is
specified, 30 days from the start time is used as a default.
-h Prints a short summary of the options and arguments to dnssec-
-p Use pseudo-random data when signing the zone. This is faster,
but less secure, than using real random data. This option may be
useful when signing large zones or when the entropy source is
Specifies the source of randomness. If the operating system does
not provide a /dev/random or equivalent device, the default
source of randomness is keyboard input. randomdev specifies the
name of a character device or file containing random data to be
used instead of the default. The special value keyboard indi-
cates that keyboard input should be used.
-t ttl Specify the TTL (time to live) of the KEY and SIG records. The
default is 3600 seconds.
Sets the debugging level.
key The list of keys to be included in the keyset file. These keys
are expressed in the form Knnnn.+aaa+iiiii as generated by
The following command generates a keyset containing the DSA key for
example.com generated in the dnssec-keygen man page.

In this example, dnssec-makekeyset creates the file keyset-exam-
ple.com.. This file contains the specified key and a self-generated
The DNS administrator for example.com could send keyset-example.com. to
the DNS administrator for .com for signing, if the .com zone is DNSSEC-
aware and the administrators of the two zones have some mechanism for
authenticating each other and exchanging the keys and signatures
