CANTOR slid the whole alphabet along by a fixed amount before sending.
Shift10
How to read it
- Every letter was moved FORWARD by an amount.
- To read it, move every letter BACK by that same amount.
- When you run off the front of the alphabet, wrap round to Z.
Worked example
With a shift of 10, the sender turned A into the letter
10 places further along the alphabet. Going back the other way is
how you read it. Count carefully — and remember A comes after Z when you
run off the end.
