## How does it work?

|
|
|
The tool uses a numerical key to shift the message's characters.
|
|
|
|
|
Only alphabetical characters are shifted.

|
|
|
Say the key is '1234' and the message is "Hello world".
|
|
|
|
|
We start by shifting "H" to the right once: "I".
|
|
|
|
|
Then we shift "e" to the left twice: "c".
|
|
|
|
|
We keep doing this until we get: "Icohp urnmb".
|
|
|
|
|
|
|
|
|
|
The alphabet and key are wrapped around.
|
|
|
|
|
So the actual key is `123412341234123412`...
