DNSSEC Validator Extension

DNSSEC Validator (2.1.0 version)

DNSSEC Validator is a web browser add-on, which allows you to check the existence and validity of DNS Security Extensions (DNSSEC) records related to domain names in the address of the webpage currently displayed in your browser window. The result of this check is displayed using colour keys and information texts in the page’s address bar. For more imformation and/or troubleshooting consult the project's homepage (http://www.dnssec-validator.cz/documentation.html).

Works for Chrome: Windows 32-bit, Linux x86/x86_64, Mac OS X x86/x86_64

Note: If you have already installed this extension in development mode, you have to remove it manually before installing the version from Web Store repository. After the installation of the DNSSEC Validator 2.1.0 please check the settings of the installed add-on. It should be reset to the default value \"Without resolver\". This value will provide correct behaviour of the validation process on most internet connections.

DNSSEC Validator contains binary NPAPI plug-in, thus you will get the warning \"This extension can access all webpages you visit and all files on the computer.\" upon installation. However, only thing that is accessed is the system resolver setting.

A nice 3-rd party howto on installation and usage can be found at http://www.internetsociety.org/deploy360/resources/how-to-add-dnssec-support-to-google-chrome/.

Christian Elsen (ID: 000000183783ef0c) Voted 5 ★ - Updated 06/05/2014 Great tool! Really useful and I wish Google Chrome had this functionality already build in. It would be great if the version available here could be upgrade to the latest, so it will include TLSA validation as well.
