Someone suggested a timer-based daemon earlier in this thread. It looks reasonable at first glance, but in security matters, I'm reluctant to trust version 0.1 of anything. Peter Gutmann's cryptlib includes a well-analyzed daemon: http://www.cs.auckland.ac.nz/~pgut001/cryptlib/ John Denker's turbid, using a sound card without microphone, looks very good: http://www.av8n.com/turbid/paper/turbid.htm -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
