February 8, 2012 -- Security researcher Moxie Marlinspike is calling on the support of browser developers to participate in his new open-source project that is designed to authenticate a secure sockets layer certificate's credentials, according to a report by The Register. Convergence, which is currently in its Beta phase, is available as a Firefox add-on and enables users to query notary servers so that they can ensure the legitimacy of an SSL certificate attached to a particular site.
