In this algorithm, each letter of the Plaintext is shifted a number of positions based on the Key provided. PlainText: Hello! Each letter of the plain text is shifted three times to the next letter.For example, if key is 3 then we have to replace the character by another character that is 3 positions down to it. Like A will be replaced by D, C will be replaced by F, and so on. For decryption just follow the reverse of the encryption process. Below I have shared a program to implement caesar cipher in C and C++.The Caesar cipher decoder will encode (or decode) the message by the shift amount and display the result. It will also show the mapping between the plain text and cipher …Otherwise, in case of a small letter, the letter will repeat. You need to get the letters position in alphabet, apply the shift and convert it back to unicode. A working example of your code is given below: output = "". c = str() for c in line: if c >= "a" and c <= "z": x = ord(c) - 97 #small a. x -= 3.2075. Decode the Slanted Ciphertext.
