Mailvelope Extension

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™
• WEB.DE™
• 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.

Hendrik Scheider (ID: 0000000d39213545) Voted 5 ★ - Updated 05/01/2023 Out of the box a pure delight: It ! Just ! Works !

Gwyneth Llewelyn (ID: 0000001e700c951c) Voted 5 ★ - Updated 04/03/2023 In one word: it just WORKS. Goodbye, Gmail reading your email and profiling you based on what keywords you type. Mind you — at least for the free version! — this is a minimalist approach to PGP encryption on a web-based email interface, such as provided by Gmail. It allows you to read and write encrypted messages, and is reasonably simple to do so (you get a BIG Mailvelope icon to click :-) ). If you're a die-hard PGP power user, you can get Mailvelope to use whatever keyrings you already have on your system. If you're just starting, and just need to keep a handful of keys around, and will never use any other browser, then you can simply store your keyring in the browser itself (it's *very* safe to do so).
