Does stopping and restarting lose progress?

[GhislaineDeF]

I've been running for about 30 days now, and based on the calculations from #27 I expect the average on my system for the key I'm trying to find to be around 90 days.

It would solve some headaches if I could reboot the server before then. If I stop, reboot and restart the program, is there some sort of progress that I lose or am I equally as likely to find a key as if I hadn't stopped it, losing only progress in the time my server was shut off rather than the full 30 days of trying?

If you ran the program with a passphrase, you will loose your progress by shutting down the program unless you also ran it with checkpointing enabled. If you did not run it with a passphrase, the keys tested are non-deterministic (ie. random), so there is no progress to lose and you can start and stop the program whenever you want.

Thank you for the quick and clear response! That helps me a lot.
