See exactly what DKIM public key is published for a selector, and whether it's structurally safe and usable.
MXFend reads the published DKIM key record for a domain and selector and reports exactly what it finds: key algorithm, RSA modulus size or Ed25519 key length, revocation, and restrictions. This inspects a published public key — it does not validate a real email signature and does not prove any specific message passed or failed DKIM.
