Thats a Programming mission, not an Application one.

Anyways, you have to take that input, and do something with it. Result is (as the page already stated) a string that isnt nessecarily readable.

I believe the 'Shift: -6' refers to this being what is known as a Caesar cipher... doesn't it?

I think.. you would do the shift on the string.. ex.
65 -6= 59
66 -6= 60
67 -6= 61
68 -6= 62
or
;
<
=
>

not positive.. but..
