HOWTO
Check if keys match
dig myselector._domainkey.example.com txt
and save the bit from "p=" to public.key.b64
openssl enc -base64 -d -in public.key.b64 -out public.key openssl rsa -pubin -inform DER -in public.key -noout -modulus
and compare the shown modulus with
openssl rsa -in private.key -noout -modulus
They should be identical
