I guess things probably changed a little bit in 5.1. Thanks for the heads up, Adam. I guess things probably changed a little bit in 5.1.

I have used your GenerateMySQLHash function in one of my C# apps, and I noticed that it doesn't generate the correct MySQL >4.1 hash. For example, I chose a simple test password and ran it through both your function and the MySQL 5.1 command line: Your Function: *46D8C7BAEFF461D8F821A61F07CD06FFB2D0 MySQL 5.1: *46D8C7BAEFF40601D8F821A601F07CD006FFB2D0 I found that changing b.ToString("X") to b.ToString("X2") at line 9 of your code fixed the problem.
