Take privacy into your own hands

About PassLok

PassLok is a free app that provides simple, highly secure encryption for text and files. There are two flavors of PassLok:

PassLok Privacy: a standalone app that runs on any device and is independent of any other app. In addition to the web app, there are versions for Chrome, Firefox, and Android. Related to this is FusionKey, which adds password-management functions. You can get it as an extension for Chrome or Firefox.

PassLok for Email: a Chrome and Firefox extension that integrates PassLok functions into popular webmail clients. Currently it supports Gmail, Yahoo, and Outlook online. There's also PassLok Universal, which adds password-management functions and works with any email service. You can get it as an extension for Chrome and Firefox.

Both are 100% client-based, which means that there is no server holding your private data. Both include five modes: regular, self-destruct, chat, anonymous, and shared-password.

PassLok is based on NaCl, a fast, modern, highly secure encryption engine. Because of this, PassLok is the easiest to use, most powerful email encryption app in the market.
