#TKEYBOARD SHIFT RIGHT CIPHER MOD#
This allows us to easily identify the row with p mod 4 and eliminates the need for explicit separators between the rows. For example, upon encrypting the message cookie using a shift cipher with encryption key 3, we obtain the encoded message (or ciphertext): FRRNLH.
Then the resultant will be our Plain Text or Decrypted Text. The alternative is to use the inverse of the Caesar cipher key which is always 26-x. For example, if the key was ROT 2, then the letters shift back left 2 letters. Now, repeat the Step-1 and Step-2 for the cipher text by implementing this change. The first method takes each letter of the ciphertext and shifts it to the left by the key’s number. Here in Decryption, we shift the values towards left by adding/placing key at last index. Unused positions are padded with underscores and the last ones are simply discarded. This will be our 'key' that will allow us to encrypt and decrypt the message.
The Caesar cipher works well as an introduction to ciphers, but it’s not overly. Here, you can experiment with Atbash, mixed alphabet, and a very useful variation on the Caesar shift cipher that uses ASCII characters. This is much easier to implement if we flatten this disk shape into a straight line as above: Now all we need to do is 'shift' the bottom row to the right 1 char at a time, taking the right-most character and adding it to the left-most position. It works like this: First, choose some text that you want to encrypt. In addition to the Caesar cipher, you will see names like Atbash, Affine, Beaufort, Hill, and others. We look for the position p of each character of the input within a string S where the keyboard rows are interleaved: the first 4 characters are '1QAZ' (first column of the keyboard), the next 4 characters are '2WSX' (second column of the keyboard) and so on. The Caesar cipher is one of the earliest and simplest ciphers that were invented.
