TLSA Validator Extension

TLSA Validator allows you to check the existence and validity of DNSSEC signed DNS records for domains. If a valid DNSSEC chain to the domain is found it will also check for the existence of TLSA records. TLSA records can store hashes of remote server TLS/SSL certificates. The authenticity of a TLS/SSL certificate for a domain name is verified by DANE protocol (RFC 6698). DNSSEC and TLSA validation results are displayer by using several icons. Additional explanatory texts are shown in the page’s address bar. Clicking on a given icon symbol reveals more detailed security information.

IMPORTANT! This add-on communicates with an external binary application through the native messaging interface. The binary application is required for correct working of the add-on. The binary can be downloaded from www.dnssec-validator.cz/pages/download.html#package. Keep in mind that the version of the binary and of the extension must match.

Farhan Islam (ID: 000000f9cb1c443a) Voted 1 ★ - Updated 01/31/2020 The module had stopped working, and they had official announcement about this on there website. https://www.dnssec-validator.cz/

Andy Haubenschmid (ID: 0000001cbce940e4) Voted 5 ★ - Updated 04/08/2018 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.
