Grid Transposition Cipher

The Grid Transposition cipher is just another type of transposition cipher. First make a grid that can fit all of the letters, you can do that by taking the square root of the total number of letters, if it comes out as a decimals round up. If there are extra spaces add X's. Then you scatter the numbers in a random order. Then Match the coordinates onto the second grid. Best codes would come out as EDSEBSCTO. To decode it all you need to do is make another grid with the letters in the correct order. Finally Match the coordinates onto the correct grid.
