I sometimes received emails on Gmail that people encrypted using my OpenPGP public key. I am looking for a browser extension that can:

  • decrypt e-mails in Gmail using my OpenPGP private key (e.g. automatically or by clicking on some "decrypt" button -> I don't want to have to copy-paste somewhere as I currently do)
  • work within the Gmail interface (e.g. I don't want to have to POP/IMAP)

and if possible:

  • works with Google Chrome and Microsoft Windows 7
  • free

Mymail-Crypt for Gmail™

  • Integrates with the GMail interface
  • You can decrypt e-mails with a "decrypt" button
    test e-mail
  • Works with Windows 7
  • "This project is no way affiliated with Google™."

    The project is powered by OpenPGP.js. OpenPGP.js aims to fully implement the RFC 4880 OpenPGP standard. This project is still a work in progress, but supports a variety of key importation/generation abilities to encrypt and decrypt messages. Please see http://openpgpjs.org/ for details on this project.


You can use End-To-End:

  • open source and free
  • developed by Google
  • released on June 3rd, 2014
  • supports RFC 4880 (OpenPGP Message Format) and RFC 6637 (Elliptic Curve Cryptography (ECC) in OpenPGP)
  • beware it is in beta and may have security issues
  • not available in the Chrome Web Store yet
  • According to the linked page it's in alpha, not beta. Not that it makes much difference...
