dnssec-makekeyset — DNSSEC zone signing tool
dnssec-makekeyset  [-a] [-s ] [start-time-e ] [end-time-h] [-p] [-r ] [randomdev-tttl] [-v ] {key...}level
        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.
    
Verify all generated signatures.
start-time
	       Specify the date and time when the generated SIG records
	       become valid.  This can be either an absolute or relative
	       time.  An absolute start time is indicated by a number
	       in YYYYMMDDHHMMSS notation; 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.
	  
end-time
	       Specify the date and time when the generated SIG records
	       expire.  As with start-time, an absolute
	       time is indicated in YYYYMMDDHHMMSS notation.  A time relative
	       to the start time is indicated with +N, which is N seconds from
	       the start time.  A time relative 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.
	  
Prints a short summary of the options and arguments to dnssec-makekeyset.
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 limited.
randomdev
	       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 indicates that keyboard
	       input should be used.
	  
ttlSpecify the TTL (time to live) of the KEY and SIG records. The default is 3600 seconds.
levelSets the debugging level.
	       The list of keys to be included in the keyset file.  These keys
	       are expressed in the form Knnnn.+aaa+iiiii
	       as generated by dnssec-keygen.
	  
        The following command generates a keyset containing the DSA key for
	example.com generated in the
	dnssec-keygen man page.
    
        dnssec-makekeyset -t 86400 -s 20000701120000 -e +2592000 Kexample.com.+003+26160
    
        In this example, dnssec-makekeyset creates
	the file keyset-example.com..  This file
	contains the specified key and a self-generated signature.
    
        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 securely.
