Is it safe to use rng-tools on DO?
rng-tools increases the entropy pool significantly and upon running
rngd -v it lists Intel/AMD hardware rng and DRNG. But testing the hardware rng using
rngtest -c 1000 </dev/hwrng returns no such device. My question is whether rng-tools is actually supplying the entropy pool with high-quality random numbers, or should I use something like haveged instead?
