Finally an update to DKIM. See they slide in Ed25519 sigs pretending it wasn't already a standard that nobody implemented for like a whole decade (mostly, i think proton and a few smaller players support those sigs but none of the big guys budged.)

Doing something odd with JSON i think. Where is that supposed to go lol. Are we going to blow up the headers even more with JSON structures Header canonicalization on SMTP email is so much fun i know. :) i wrote my own signer. For v1 anyway. Took quite a bit of time for me to figure out that there can be no CRLF at the end of the header block you are signing :)
