ZRTP is the protocol specification we developed that describes how to negotiate session keys for a secure VoIP phone call. We have a software development kit, a subroutine library for developers that implements the ZRTP protocol, called libZRTP, which can be integrated into VoIP applications. And we have a complete software application called Zfone that showcases the libZRTP SDK. Zfone is ready to run for end users, not just VoIP developers. Zfone is not itself a VoIP client– it is an “adapter” that lets you make secure phone calls using your favorite VoIP client. If you are developing your own VoIP application and you want to build in ZRTP capabilities, you should get our libZRTP SDK. If you just want to make secure VoIP phone calls as an end user, get Zfone.
