# Edit to your taste. Using /dev/random would be more secure, but may
# block if randomness is not available, thus the default is
# /dev/urandom. $how_random determines how many bits of randomness to take
# from the device. You should take enough (read SSLeay/doc/rand), but
# beware that randomness is limited resource so you should not waste
# it either or you may end up with randomness depletion (situation where
# /dev/random would block and /dev/urandom starts to return predictable
# numbers).
#
# N.B. /dev/urandom does not exist on all systems, such as Solaris 2.6. In that
# case you should get a third party package that emulates /dev/urandom
# (e.g. via named pipe) or supply a random number file. Some such
# packages are documented in Caveat section of the POD documentation.
