Okay. so i downloaded the decryption php script (the one in the commented link), made some small configurations, and it works fine. i even tested it: i encrypted a string using the encryption provided by HTS, decrypted it with that script, and its ok.
I have a sudoku solver i made quite a long time ago. i used it many times on real sudokus, so im sure its not the problem.
I take the unsolved sudoku, solve it, hash the solution using sha1, and use it in the decryption script. but all i get is a bunch of unrecognized characters (e.g 6<fax*)
can anyone tell me what am i doing wrong?
