Paste a DKIM TXT record and check selector name, version, key type, public key tag and obvious warnings.
This checker helps read a DKIM DNS TXT record before a mail authentication rollout or support ticket. Enter the domain, selector and pasted TXT value to review the record locally.
What it checks
The report parses DKIM tags, builds the selector DNS name, checks v=DKIM1, key type, public key presence, revoked empty keys, duplicate tags and suspiciously short RSA key material.
Scope
The tool does not query DNS and does not verify a message signature. It only analyzes the DKIM record text you paste.
