It carries your data.

It depends - device drivers can add entropy. It does include interrupt stuff, but not, by the looks of it, timing information, so I await the results of your experiments with interest (note, btw, I didn't have much to do with FreeBSD's /dev/random). _______________________________________________ Full-Disclosure - We believe in it.
