Gcryptr: A Gmail Encryption Helper

Gcryptr is a Chrome plugin that let's you encrypt simple email messages.

Note: this was created as an assignment for an NYU School of Engineering course, CS-GY 6903. This has not been vetted and should only be treated as an educational tool.

Getting Started

To install the extension, clone the repo and:

1. Open Chrome and go to chrome://extensions
2. If the Developer Mode toggle is set to "-", click it to go into Developer Mode.
3. Click "Load unpacked extension..."
4. Choose the chrome directory in this repo.
5. Enable the newly added extension.
6. Head to your Gmail account, and compose a new message or open an encrypted message.

Project Credit

Gcryptr is built on top of the hard work of other enterprising developers. Please support their projects.

Cryptography is difficult and I'm not a cryptographer. Therefore, Gcryptr uses an open source PGP library, kbpgp.js.

Interfacing with the Gmail interface is handled by the awesome gmail.js library.

Styling and widgets are built using jQueryUI

TODOs

• Encrypt attachments, inline images.
• Support symmetric, passphrase encryption
