Editors' review

An extension for Thunderbird and SeaMonkey, Enigmail is a must-use for anybody who's concerned about sending e-mail that can be read by anybody, including your Internet Service Provider. It's not intended to encrypt all of your mail, although you can certainly do that. Rather, it's best used for ensuring that even remotely sensitive e-mails don't get read by the wrong person.

It uses the OpenPGP standard to digitally sign your e-mail, and can be configured to accommodate multiple e-mail accounts. One hang up is that it's impossible with the current version to permanently decrypt e-mails, which can prevent them from being found by the otherwise-powerful Thunderbird search tools. Enigmail is an invaluable resource for messages containing sensitive information. An installation guide, which is essential for all but the most advanced power users, is available at the Enigmail Web site.

    "Once you figure it out... it works great"

    October 22, 2012   |   By Noyzvelot

    Version: Enigmail 1.4.5


    1. Learn how encryption works and appreciate monotype fonts (eventually...)
    2. No one (including yourself) will ever be able to read encrypted emails without the key
    3. Very easy key management takes place mostly behind the scenes once you get a "circle of trust" started.


    1. You have to also download/install another program, whose documentation is nearly incomprehensible, in order to use this
    2. You have to be able to make sense of PKI terminology
    3. Geekiness and/or paranoia is a must, otherwise you probably won't stick with this.


    Unless you're already an old-school Radio Shack type tech geek, you will probably have a difficult time figuring out Enigmail. But once you do, rest secure in the knowledge that your encrypted emails are indecipherable to prying eyes for the next thousand years or so.
