>>>I'm using Craig Boyd's FLL to create a SHA-256 hash code. After I call it with HASH(m.lcHashme, 2) , it returns:
>>>
>>>"ƒ]ÊQ“öu 9/s¦«†8‚žZ¸™€Ç)ÚSìˆÅ"
>>>
>>>If I then encode it to hexBinary using STRCONV("ƒ]ÊQ“öu 9/s¦«†8‚žZ¸™€Ç)ÚSìˆÅ", 15) I get:
>>>
>>>"835DCA0E5193F675A0392F73A6AB118638829E5AB89980C729DA05538DEC88C5"
>>>
>>>The issue that I'm having is that I'm supposed to get "52e7e37b8c5f6cde8505a9d4a6324ca486d5aa13dde18cb7fa58690978343f72" because the web service that I'm going to call generates the latter. If it helps, I've been told that the web service generated the value from the hash code in bytes: 82 -25 -29 123 -116 95 108 -34 -123 5 -87 -44 -90 50 76 -92 -122 -43 -86 19 -35 -31 -116 -73 -6 88 105 9 120 52 63 114

Well, it's not much of an "extreme" - HASH() supports only 7 different types, it would take you only seconds to try them all against what the web service gives you.
