You'd have to make sure you don't get interference from actual signals - but Bill's suggestion of MD5 checksums would probably minimize that, as long as the noise-to-signal ration is quite high (never thought I'd be recommending *that* on a public forum ;) ) I've heard of someone using a lava lamp as an entropy source, or thermal noise in semiconductors. Also, radioactive decay makes a good source... http://www.fourmilab.ch/hotbits/ And atmospheric noise (www.random.org). -Micah _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
