Crypto Box is a tool to encrypt text by moving the
letters. This is done by shuffling the rows and columns
of the text square. Retrieving the original position of
the letters has proven to be a real challenge due to the
large number of possible moves and the complex way the
letters travel around the square. Even the simplest
shuffles with a few steps create a true brain-teasing
puzzle. More steps means a more complex encryption. There
are 39 ways to move a row or columns in the box (moving a
row back is useless so the 40th doesn't count). For five
steps this already gives 40 * 39 * 39 * 39 * 39 =
92,537,640 possible combinations. Each further step
multiplies the result with 39. With only 40 steps you
will have 4.5x1063 combinations, comparable
with an enormous 212 bit key!
The program has an easy interface to
shuffle the rows and columns, and each step is recorded,
This enables running the key automaticalle or manually.
Both text and key can be imported from, and exported to
the clipboard in various formats. This small program -
only 105 Kb - is ideal to create your own puzzles or
encrypt short messages.
