Hi Stephen,
Thanks for the reply. You're absolutely right. It
does appear that I am not blocked indefinitely...it
certainly does take a while to gather entropy. I was
using nBytes = 1024. Then I tried 512. Still very
long time.
Any suggestions on what a number should be for
acceptable randomness?
Does anybody have any alternative suggestions? Does
anybody know how Apache seeds the OpenSSL PRNG on
Windows? I think Apache uses OpenSSL don't they?
Thanks,
Ed
