Philip Zimmermann introduced Zfone encrypted VoIP

by Ryan Block, posted Mar 15th 2006 at 10:47AM

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).

Wow, PGPfone. That name brings back a lot of memories. I remember using that back in the day. Nice to see something on the same order being modernized.

Out of luck? Not with a little help from the freeware VMWare Player and their pre-built Ubuntu Appliance. :-)

Well at least the Windows users won't have to wait to long as it says mid-April for a Windows program.

This is sweet! I always thought that PGPfone was way ahead of its time. It's good to see that Phil is still around and has applied his idea to modern protocols. :)
