Zimmermann's approach to secure VoIP

As reported by many web sites, Philip Zimmermann has a new project: Zfone. This beta software allows encryption of SIP-based VoIP systems (i.e. Gizmo, Wengo, etc.), without the need of a PKI. In the future, Zimmermann expects the underlying protocol will be integrated into standalone secure VoIP clients.

Currently, binaries are available for Mac OS X and Linux. A Windows build should be released around mid-April.

Update 2006/5/23: they finally have a Windows XP version. :-)
