This is a JavaScript 1.2 implementation of a letter-pair
replacement solver, also known as a substitution cipher. This is the
kind of puzzle where A is N, B is O, C is P, etc. It can also be
called a cryptoquip or a cryptogram in the local newspaper.

To use it, you just define a "key" and the letters in the upper
part will be translated and shown in the lower part. This is only a
tool to help you out – it can not automatically solve the puzzle for
you.

In a related vein, you can check out the ROT13 encoder
which swaps letters from the first half of the alphabet with the
second half (and vice versa), or the Caesar cipher
where you essentialy "slide" the alphabet over to the left or
right.

Quickly swap two letters by typing them in here: or reset the letters to A-Z or Z-A.

decode alphabet: ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789
