How it works

DKIM (DomainKeys Identified Mail) uses a public/private key pair to sign outgoing emails. The public key is published as a TXT record at {selector}._domainkey.{domain}. This tool performs a live DNS query via Cloudflare DNS-over-HTTPS to retrieve and parse that record, displaying the key type, hash algorithm, and public key.
