Speech privacy technophobes need not apply

Anyone can download Speak Freely, enable its essentially unbreakable encryption, and then talk telephone-style via the Internet with any other person in the world with a similar installation. The conversation will enjoy complete privacy because every utterance is encrypted on-the-fly before being transmitted. The software costs nothing, and because it is installed locally, it does not go through any vendor´s servers (as is the case with much commercial software that offers voice-over-IP, or VoIP, services), which could act as convenient interception points. Users can select the encryption algorithm they like (Blowfish, 128-bit IDEA, DES, or even a concatenation of two or more of these) as well as their encryption keys for each conversation; they could even change encryption during the course of the conversation. Less user-friendly, though comparably effective for voice encryption over the Internet, are other free software packages such as Nautilus (which offers triple DES, IDEA, and Blowfish encryption) and Pretty-Good Privacy (PGP) Voice, both of which are downloadable from numerous sources.
