|
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`...
