Special and important messages
and messages are often encrypted or "written in code.". There are many opportunities, at Ver- and apply math to decode.
Let's take the message: Sikox ndnln nueee adsds kteoe? It stands out, that this message has five groups of letters and that each of these groups contains five letters. This is our first clue. If we put together the first letters of each group, we get: snnak. Surely that means nothing. We wouldn't find any meaning either, when we split the second letters of each group together: idudt. what would happen, if we wrote down these groups from the back? It looks like this: can you. We have now found our key.
We now recognize a square code. Contains the whole message 25 letters and consists of five words of five letters each. That means, that the message in a square with five longitudinal- and five rows was written. We know too, that it was written backwards in code form.
If we take the coded message and fit it backwards into the square of five, we find:
At the end, to fill the space, there is still an x. We can now read the encrypted message!
