That's a good point.

However, I only need a random number once ever per customer; it's to
encrypt their license keys & privileges.

I could stockpile a couple of hundred random numbers for later use . . .

:)

The issue is how to turn the random number, from whatever source, into an
RSA pair.  I didn't see any way from the openssl man page to feed it a
random number; it seems to rely on the system.

This part only needs to run under unix; there isn't a chance that I'd be
running a server under windows . . . (my son in law is less than pleased
that I won't even allow windows machines on my home network . . .)
