Talk:Playfair cipher/to do

The example is not correct. There is not a 5x5 grid, it is a rectangle 6x4 - that doesn't make sense. Then there are the 'table'-examples and the 'big_picture'-examples. They don't fit together and are mixed up. So there should only be one kind of example.

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:

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" we get the cipher as

HI DE TH EG OL DI NT HE TR EX ES TU MP                            ^


 * 1) The pair HI forms a rectangle, replace it with BM
 * 2) The pair DE is in a column, replace it with OD
 * 3) The pair TH forms a rectangle, replace it with ZB
 * 4) The pair EG forms a rectangle, replace it with XD
 * 5) The pair OL forms a rectangle, replace it with NA
 * 6) The pair DI forms a rectangle, replace it with BE
 * 7) The pair NT forms a rectangle, replace it with KU
 * 8) The pair HE forms a rectangle, replace it with DM
 * 9) The pair TR forms a rectangle, replace it with UI
 * 10) The pair EX (X inserted to split EE) is in a row, replace it with XM
 * 11) The pair ES forms a rectangle, replace it with MO
 * 12) The pair TU is in a row, replace it with UV
 * 13) 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".
