What is PGE you say to yourself? PGE means "Pretty Good Email," which is an email encryptor based on the "Pretty Good Protection" specification. The core selling point of PGE is that all encryption happens locally, on the client computer before any data is transmitted. Thus, one can rest assured that even their most secret of secrets will not fall into the wrong hands during transmission as the only time the unencrypted file will be seen is on the client computer at the time of the emails inception, and at the time of opening by the intended recipient.
Using OpenPGP.js and the Keybase API as well as KBPGP.js we check a users email against existing accounts to figure out their public keys and then use this information to encrypt her email. This is currently written to work with FastMail and expressly being tested as a Greasemonkey/Tampermonkey script. It is the intention of this project to bundle it as a "Chrome" extension, which given proper care in our
XMLHttpRequest header will be able to parse data coming from any email provider and thus render the same surface.
Ideally, once the core of the interceptor is written it will then be transcribed into a
popup.js file which when bundled with the rest of the Chrome extension configuration files can then be downloaded, compiled locally and imported as a Chrome extension via the dev tools.
State of development-- the request handler has been written and works exceptionally with FastMail in Chrome. It is the encryption and decryption of the body via the Keybase API, as well as
OpenPGP.js, that is currently being actively developed.
I will add more code blocks and an in-depth explanation of the project once the interceptor is 100% functional. Currently I am able to encrypt emails most of the time with a less than desirable decryption frequency. But hey, at least efficiency and run time isn't the issue I'm trying to resolve!
