Transform a dnskey rr to a ds rr
ldns-key2ds file
ldns-key2ds is used to transform a public DNSKEY RR to a DS RR. When run it will read file with a DNSKEY RR in it and it will create a .ds file with the DS RR in it.
It prints out the basename for this file (K<name>+<alg>+<id>).
By default it takes a pick of algorithm similar to the key algorithm, SHA1 for RSASHA1, and so on.
-f
Ignore SEP flag (i.e. make DS records for any key)
-n
Write the result DS Resource Record to stdout instead of a file
-1
Use SHA1 as the hash function.
-2
Use SHA256 as the hash function
Written by the ldns team as an example for ldns usage.
