WebHere is how to do it: Let there exist a mapping M ( c) = W which maps every distinct letter c to some word W, for instance "e" -> "echo", "d" -> "delta", and so on. You can use more than one mapping, but this will do fine. The mapping must be bijective (one-to-one, so that it can be reversed for decryption).
