Several contemporary basic-objective CPUs even have hardware random variety turbines. This helps a good deal with this problem. The very best apply is to collect some entropy in other means, nevertheless maintain it within a random seed file, and blend in some entropy from the hardware random amount generator.
Introducing a passphrase presents additional protection in the event that anyone is ready to gain use of your non-public crucial file, supplying you with time and energy to change the keys.
