So I realise that as a user of CentOS 7 you might not be getting
RDRAND support. You can tell by looking for soemthing like:
[ 1.138541] random: crng done (trusting CPU's manufacturer)
near the top of your "dmesg" output.
Those with kernels not new enough to trust RDRAND (or who want to
disable RDRAND because NSA) may experience that boot time entropy
starvation and may want to use BitFolk's entropy service or
something.
