Hint 2:

Hint 1 is in UTF-8 in Hex

    $\begingroup$ Are you sure the puzzle is only "Shift by 0x83" and the hint is not needed but only augmenting the puzzle?? $\endgroup$

1 Answer 1


They all start with an 8, including the shift. Makes me think it's a question of subtraction. If I convert to decimal and subtract the 0x83F (i.e. 211110) from each of the digits, I get


which is not only UTF-8, it's entirely ASCII.

Can you confirm this password works?
