Tiger Envelopes

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.

Requirements:

Windows NT/2000/XP
