Thanks for answers, Jeff. But I still have questions:
Why not allow OpenSSL to auto seed itself?
Because on Windows we have not /dev/random and that's why I think that auto

Ok I don't know if I understood your problem correctly, but if you're looking for ways for seeding you can always use current system time, I believe this is pretty much available on all systems.
Hope that helps."Bibbs, Christopher" <[EMAIL PROTECTED]> wrote:
