DKIM Key Generator

Generate a DKIM keypair and the DNS record you need to publish

Nothing is stored: the keypair is generated in memory and discarded after the response. The private key is shown once over HTTPS — save it immediately and never share it. Deploy it only on the mail server that will sign outgoing mail.

Domain, selector and key size

The domain you'll send mail from (the FQDN of the From: address).

Defaults to intesys-s1 if left blank. Use a unique selector per signing key.
