Why wasting CPU cycles in mp3 encoding ? Target is /dev/null anyway.
It really makes no sense to store it, it's just an exabyte
for the "entropy pool" of /dev/random.
Please read drivers/char/random.c:
* Sources of randomness from the environment include inter-keyboard
* timings, inter-interrupt timings from some interrupts, and other
* events which are both (a) non-deterministic and (b) hard for an
* outside observer to measure. Randomness from these sources are
So if I would patch the driver, I could remove the hash transformation
because her speak is (a) perfect non-deterministic and
(b) extremely hard for an outside observer to measure.
