Hashes are intentionally one-way. You can't get back to the original source other than doing a brute-force search of source strings until you find one that matches the hash. Obviously that's really time intensive, especially if the source string is of arbitrary length. That site you link to simply has a database of known strings and their MD5 hashes and will do that brute-force search for you. So unless you have a common string, chances are slim it'll help.
That said, if PHP was using an MD5, then it wasn't decrypting it either, only using it for comparisons. So you should be able to implement the same functionality in CF, despite the fact that you don't know what the source data is (because PHP doesn't either). cheers, barneyb On Sat, Apr 18, 2009 at 10:01 AM, Chad Gray <[email protected]> wrote: > > Hello, > > I need to decrypt a hash.
