Hi all,
Might there be a way to pass 9 sets of 9 characters to be used as the
symbols in a solved sudoku puzzle? It would be even better if there
were some way to show both the original 1-9 and the replacement
characters at the same time, maybe by having a larger gray number
background, with a solid black character foreground.
What could this be used for, you're probably wondering?
Say you want to print out a password card, with a set of strong
passwords that you could use on one or more accounts. But if
someone's looking over your shoulder, you don't want it to be obvious
which password you're using.
Generate 9 strong passwords following a certain pattern. Here's one
that I created randomly as an example
Qd"4xkD9f
that's 2 Uppercase (U), 4 lowercase (l), 2 digits (d), 1 symbol (S).
Let's say that you create 9 such passwords, all with the sequence
above:
UlSdllUdl
If you then substitute these 9 passwords into a solved sudoku puzzle,
you are guaranteed that *every* 1-9 sequence you find in the square
will contain some set of 2U, 4l, 2d, 1S characters.
You could then print this out and carry it with you to remember your
password. Someone looking over your shoulder wouldn't know which
sequence you were using -- all you have to remember is "upper left
corner", or "column 6", or even "row 3, using the original order".
Nice, eh?
The password generation is another problem. But let's say that I
handle that myself and pass in the string myself. Is that an easier
problem to solve?
