Re: Random #'s via serial port dongle?

The easiest way to get true random numbers on a PC nowadays is with a sound board, preferably 16 bit. Just MD-5 hash some gibberish speech and/or background noise. I am looking at various ways of generating good random numbers for my IP security protocol, so I'm thinking about this stuff. Unfortunately I can't always depend on there being a sound board, so I'm still open to other ideas. Recently I tried looking at phase jitter between the CPU and timer crystals, but this doesn't work on every machine. Timing keyboard hits is a tried-and-true technique in PGP, but I can't necessarily rely on that either (I want this to work in a standalone system that boots by itself). Suggestions would be appreciated. Phil
