JackPair Encrypted Phone Add-On
JackPair is a clever device encrypts your voice between your headset and the audio jack. The crypto looks competent, and the design looks well-thought-out. I'd use it.

I'll second Scared.
How the heck does this thing work? If you play white noise into a cell phone the white noise the other side hears is generated in the receiver and has little or nothing to do with the input. The encrypted signal has to be something that resembles human speech so that it is pass through the codexes in the link relatively unchanged.
Has anybody played back the encrypted output? Does it sound like human language?
