Is there a tool available for Linux systems that can measure the quality of entropy on the system?I know how to count the entropy:cat /proc/sys/kernel/random/entropy_availAnd I know that some systems have good sources of entropy (hardware entropy keys), and some don't (virtual machines).But is there a tool that can provide a metric as to the quality of the entropy on the system?
Tool for measuring entropy quality?
