The Zfone Project
September 1, 2008
I communicate with friends, family, and co-workers mostly through instant messenger and VoIP clients. I already know that many instant messaging services are extremely insecure in the ways they transmit your conversations over the internet. I decided to try and find some software to help keep things a little more private. After going down a few rabbit trails I had come across Zfone.

Zfone is a fairly new secure VoIP phone software that allows users to make encrypted phone calls over the internet. The principle designer of Zfone is Phil Zimmermann, the creator of PGP, the most widely used email encryption software in the world. Zfone uses a new protocol called ZRTP, this protocol has a better archiecture then any other protocol currently used to secure VoIP. ~ zfoneproject.com
Installation is relatively simple. Once installed, launch the Zfone client. Then launch any one of the IM/VoIP Clients supported by Zfone. It is really that simple.
Zfone needs two users running the software simultaneously. I have tested this software with 4four1ones using Apple’s iChat. We both agree it is the easiest way we know to encrypt your audio and video chat sessions, when using iChat.
Thanks Zfone!





Yeah, what @wirelesspacket said. Zfone is shiznittle bam snip snap sack. No prying eyes and ears will be reading/listening to our uber secret plans of interwebz domination any longer. Take a hike snoopers!
