First a very happy en successful 2013, for you and your family :-)
I have to create a HMAC, never heard before of that, but I figured out that there is an API for that. I created a test program but it seems that whatever parm I fill with whatever value, the error is the same
CPF9DE0 : Hash algorithm not valid.
A part of the parameter I understand, but for some other it's not clear what the function is.
