+In cryptography, the TRANSPOSITION cipher is a method of encryption where the
+positions of plaintext are shifted a certain number(determined by the key) that
+follows a regular system that results in the permuted text, known as the encrypted
+text. The type of transposition cipher demonstrated under is the ROUTE cipher.
