# Linux has two sources of randomness:

# /dev/random delivers bits of high randomness but may take a while to
# collect them

# the pool with pseudo-randomness to deliver the rest of the bits
# that are requested
#
# Use /dev/random if you're paranoid. /dev/urandom is more than adequate for
# the level of security we try to achieve here.
