Although it has a dedicated interface, there's not much to do to operate this free e-mail encryption program. Tiger Envelopes works behind the scenes, and that includes configuration.
On install it automatically searches for and lists e-mail clients like Outlook, Outlook Express, Thunderbird, and Gmail. The tabbed interface leads with Status and you merely click a button to enable protection. For other Web-based e-mail clients, a configuration window walks you through the process of adding accounts. There are only a handful of advanced settings, allowing you to accept self-signed SSL certificates and exchange keys automatically when e-mail is sent and received. Other tabs let you add and delete accounts and manage keys. There was no discernible speed difference when sending or receiving e-mail using Tiger Envelopes.
Setup is easy, and this program is free. If you want an extra layer of protection, you'll lose nothing by giving Tiger Envelopes a try.

From Tiger Privacy:
Ordinary e-mail is like sending all your messages on postcards. Anyone can read it. Encryption is the answer, but it's always been so much hassle that even security pros usually don't use it. What we need is an easy way to protect our email from snoops. That's what Tiger Envelopes is. You just read and write mail, but now it's private. You don't change your mail client. There are no extra steps. The first unprotected message is the last. Everyone can run Envelopes. Installation is super simple. With one click it sets up your encryption and configures Windows Outlook, Windows Outlook Express, Thunderbird, Mac Mail, or KMail.
