I'm sorry but you're pretty much talking and not enough doing!
I have no desire to carry on a conversation about the code and the more indulge in the code with a man who on this forum has two post for all time. To me, you spam the user yet!
Sorry!
Thanks krecu for you for your clarification.
Thanks to the earlier poster advising me that the KGW is only relevant to scrypt-based hashing, that was next on my stack and you're right, I embarrassed myself by not holding my horses until I understood the details better.
Good luck.
Cheers,
Graham
