Required in C++ for VC6 (No .Net)
Require a function that can convert a key using the SHA256 Hashing algorithm and it also then needs to be Authenticated in HMAC - Its all to do with Cryptography.
I am sure this function has all ready been written and tested somewhere. Please note a simple function is required here hence not willing to pay more then $30
