Sorry Brian,

I haven't checked in for awhile. We are charging credit cards via Authorize.net. When their server responds, it returns a hash value on specific data to verify that the response was truly sent from their gateway. We have to run the MD5 hash algorithm on the same values and compare our result to theirs.
