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
