Never known such cipher (im not very good in encryption) but a fast look to wikipedia and i understood it. Anyway, if you want use matrices, an indea can be (for encription): - create a matrix r x c where r is the number of fence and c is the size of message/ r (rounded up). - fill the matrix with a 0 value - fill the matrix, from top to bottom by column, with message character by character the final encripted message coul be obtained by reading the matrix by rows ignoring the 0 values
