How to digitally sign an e-mail – Updated

I made a post in 2009 explaining how to digitally sign an e-mail with FireGPG. Unfortunately, “FireGPG is discontinued” and no longer supports Gmail. So, we need to do it differently now.

Objective: To sign your out-going emails through an on-line email provider such as Gmail or Yahoo mail.

Operation Systems: Any.

Browsers: Firefox or Chrome.

Add-on or extension for the browser: Mailvelop (get it from http://www.mailvelope.com/)

It works with: Gmail, Yahoo mail, Hotmail, and most other on-line, email providers. read more...

[UPDATE: This solution would not work with Gmail any longer, because the Firefox add-on that I was using at the time is not supported any more. Read the instructions for the updated method of signing your email here]

Requirements:

  • Operating systems: Win XP, Vista, or 7
  • Softwares: GnuPG, Firefox, FireGPG (it’s a Firefox add-on), GPGshell
  • A gmail account
  • Enough time

Go to Tools > Add-ons > Get add-ons
