Okay so I think I know what the problem is.. I downloaded a hash calculator and one of the options is telling it the format of the text entered, hex string or text string.
Does anyone know how to accomplish this? I've tried using InputBaseN to convert the string before passing it to the sha-1 function but thats not working either. Any ideas on how to accomplish this?
