Cryptography to webmail. Handy if you need private messaging. GPG is primo encryption.
FreeEnigma brings cryptography to webmail, with an ingenious set of free and open browser plug-ins that work with Yahoo, Gmail, and others. The plugins implement a version of GPG (the free/open version of Pretty Good Privacy) and scramble and de-scramble the text in your webmail before you send it and after you receive it, reducing the amount of information that webmail providers have on your communications. This is long overdue, as webmail and other hosted mail solutions are a ticking bomb, just waiting for a hacker, spook or copper to come a-knockin’, there to get a look at your private communications.
