SDCOE

There comes a time when anyone (well, anyone with an interesting life) would benefit from the use of codes. There are some codes like pig latin that are easy to decipher, and others that are really hard.
For the next couple weeks (or just one, depending on how many codes I find) I'm going to be talking about the second of the two types of codes.

#1 The Box Code.

This is a code in which you'll write your message in a box. For example, I'll encode 'Meet me after school in the gym.' You now have to count the letters to find what size square you'll be using. In this case there are twenty-five. In the case that your message doesn't have a perfect square for the number of letters, use a 'dummy' letter to fill in the extra space. Now I know to do a five-by-five box.

MEETM
EAFTE
RSCHO
OLINT
HEGYM

It doesn't have to look like a square. Now you go down the rows and write what it says.

You can add spaces randomly throughout the message if you want to. Now you give it to your friend. They'll count the number of letters and can put it in the same square, this time writing the letters down in columns.

*WARNING* Make sure your friend KNOWS about the code or they'll have just as much trouble deciphering it as They Who May Not Read The Message.
