ldns-keygen: generate a DNSSEC key pair
NAMEldns-keygen - generate a DNSSEC key pair
SYNOPSISldns-keygen [ OPTION ] DOMAIN
DESCRIPTIONldns-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>
- -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.
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.
