Mailvelope adds missing encryption and decryption features to the user interface of common webmail providers.
It supports the PGP encryption standard (OpenPGP, GPG) and is compatible with other PGP applications. Encrypt files on your hard drive with Mailvelope and send encrypted email attachments.
Mailvelope makes integrating security into your workflow seamless.

It comes preconfigured for common webmail providers like:

• Gmail™
• GMX™
• Outlook.com™
• Yahoo!™

But we also support other email providers or web applications which can be activated in Mailvelope with a one-click configuration step. For details, visit https://www.mailvelope.com/help

Mailvelope is open source and based on OpenPGP.js (https://openpgpjs.org), an OpenPGP library for JavaScript. The OpenPGP standard (based on PGP as originally developed by Phil Zimmermann) uses a combination of strong public key and symmetric encryption to secure electronic communication.

Top Extensions


What has inspired us?

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
