TLSA Validator

Check TLSA records

TLSA Validator is a Chrome extension designed to enhance your web security by verifying DNSSEC-signed DNS records for any domain. It validates the presence and correctness of DNSSEC chains and inspects TLSA records, which contain hashes of TLS/SSL certificates, to confirm their authenticity through the DANE protocol (RFC 6698).

This extension showcases validation results with intuitive icons and provides detailed security insights directly in the address bar. To function properly, it works in conjunction with an external native messaging binary application, which must be downloaded separately and kept in sync with the extension version. With TLSA Validator, users gain a reliable tool for confirming domain security beyond traditional certificate checks.

Thank you very much for this helpful security plugin. Simple shows if the domainname is secured by dnssec and if it is so, it checks if the site has a valid tlsa entry for the current address and corresponding certificate. Very easy to see, if the site could be trusted.
