How secure is the encryption?
I’ve used the best algorithms I know of and applied them in the best ways I could given the constraints of real-time audio, fallible communication networks, and the computing power of contemporary personal computers. But I’m not a professional cryptographer or cryptanalyst and even if I were, you shouldn’t believe something is secure just because the author claims it to be. One of the reasons I’m releasing complete source code for Speak Freely is to permit independent evaluation of the implementation and application of encryption within the program by experts in the community. With time, a consensus will emerge as to the degree of security Speak Freely provides and how to remedy any perceived weaknesses in future releases. Key file encryption is very insecure, but I already warned you about that; it’s intended purely as a last-ditch alternative for users with computers too slow to run any of the other forms of encryption, yet who prefer any protection, however weak, to transmitting ent
