[ldns-users] Given a DS and a DNSKEY, how do I check if the DS signs the DNSKEY?

[Calle Dybedahl]

Hello.

I’ve been trying to figure this out from the documentation and the source code, but I’m not getting anywhere, so I thought I’d ask here. 

Given two ldns_rr objects, one of type LDNS_RR_TYPE_DS and one of type LDNS_RR_TYPE_DNSKEY, what do I need to do to find out if the DS correctly signs the DNSKEY? Pointers to what documentation to read is just as welcome as plain answers.
