Philip Zimmermann introduced Zfone encrypted VoIP
While government anti-security pundits bicker back and forth about encrypting VoIP traffic, it seems like it's time to take matters into our own hands. Our man Philip Zimmerman (who you may know as being the creator of PGP) announced Zfone, a seamless PKI-free, Diffie-Hellman hashing, man-in-the-middle-detecting SIP VoIP client. Don't know what that means? Don't worry, all you need to know is if you're worried about your VoIP traffic, you need worry no more; not to be confused with his mid-90s encrypted VoIP product, PGPfone, today's encrypted VoIP brings Internet anti-wiretapping up to date with the latest in SIP and RTP protocols, as well as OS X (and Linux) support (sorry Windows peeps, you're out of luck for now).
