NAME
       ldns-keygen - generate a DNSSEC key pair

SYNOPSIS
       ldns-keygen [ OPTION ] DOMAIN

DESCRIPTION
       ldns-keygen  is used to generate a private/public keypair. When run, it will create 3 files; a .key file with the public DNSKEY, a .private
       file with the private keydata and a .ds with the DS record of the DNSKEY record.

       ldns-keygen can also be used to create symmetric  keys  (for  TSIG)  by	selecting  the	appropriate  algorithm:  hmac-md5.sig-alg.reg.int,
       hmac-sha1 or hmac-sha256.  In that case no DS record will be created and no .ds file.

       ldns-keygen prints the basename for the key files: K<name>+<alg>+<id>

OPTIONS
       -a <algorithm>
	      Create  a  key  with  this  algorithm.  Specifying  'list'  here gives a list of supported algorithms.  Several alias names are also
	      accepted (from older versions and other software), the list gives names from the RFC.  Also the plain algo number is accepted.

       -b <bits>
	      Use this many bits for the key length.

       -k     When given, generate a key signing key. This just sets the flag field to 257 instead of 256 in the DNSKEY RR in the .key file.

       -r device
	      Make ldns-keygen use this file to seed the random generator with. This will default to /dev/random.

       -v     Show the version and exit
