hello everyone,

i am making a programme on the playfair matrix in which both cipher text and plain text is given to me and im ought to retrieve the KEYWORD.

i m stuck at a point where im suppose to start entering the elements in the 5*5 matrix because when i got a starting point,i m not getting it how/where to place it in the matrix since each pair can be placed according to 3 rules(ERDL,ECDL,RECTANGULARLY) and every initial entry can be placed in 25 ways.

kindly reply
