Generated DKIM Record
Private Key
You must enter the private key in your DKIM signer. It must be kept secret, as anyone with access to it can stamp tokens pretending to be you
Public Key
The public key is the original raw 'X509' format. It's not usable in DNS directly, but it might be useful for something else.
Subdomain
Publish the generated record text on this DNS host. Format: [selector]._domainkey.[yourdomain.com] — never use @ in DNS records.
DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with.
