[edit] Playfair cipher (Talk)
Hello
The example used needs to be changed, because usually the letter removed from the box is the letter "J", not the "Q" as is done in the example.
Now:
P L A Y F I R E X M B C D G H J K N O S T U V W Z
sugested:
P L A Y F I R E X M B C D G H K N O Q S T U V W Z
If change is done, the example section will be:
[edit] Example
Using "playfair example" as the key, the table becomes:
P L A Y F I R E X M B C D G H K N O Q S T U V W Z
Encrypting the message "Hide the gold in the tree stump":
HI DE TH EG OL DI NT HE TR EX ES TU MP
^
- The pair HI forms a rectangle, replace it with BM
- The pair DE is in a column, replace it with OD
- The pair TH forms a rectangle, replace it with ZB
- The pair EG forms a rectangle, replace it with XD
- The pair OL forms a rectangle, replace it with NA
- The pair DI forms a rectangle, replace it with BE
- The pair NT forms a rectangle, replace it with KU
- The pair HE forms a rectangle, replace it with DM
- The pair TR forms a rectangle, replace it with UI
- The pair EX (X inserted to split EE) is in a row, replace it with XM
- The pair ES forms a rectangle, replace it with MO
- The pair TU is in a row, replace it with UV
- The pair MP forms a rectangle, replace it with IF
BM OD ZB XD NA BE KU DM UI XM MO UV IF
Thus the message "Hide the gold in the tree stump" becomes "BMODZBXDNABEKUDMUIXMMOUVIF".
