DKIM Record Builder & Parser

Compose a DKIM TXT record (RFC 6376) for your DNS zone, or paste an existing record to inspect every tag. Tags are validated, the public key is wrapped to 255-character chunks, and unknown tags are flagged.

DKIM tags (RFC 6376 §3.6.1)

TagMeaning
vVersion. Must be DKIM1 if present, and must be the first tag.
kKey type. rsa (default) or ed25519 (RFC 8463).
pPublic-key data, base64. An empty value means the key has been revoked.
hAcceptable hash algorithms (colon-separated). Usually sha256.
sService type — typically email or *.
tFlags: y = testing, s = i= must match d= exactly.
nFree-form admin notes (rarely used).
gGranularity (DKIM 0.x legacy, ignored by RFC 6376 verifiers).
