DomainKeys Identified Mail

Links

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
