In substitution ciphers, each letter of plaintext is encoded and decoded individually. For this task, you will create a hierarchy of classes representing a generic cipher interface, and implement one concrete substitution cipher: Vigenre. Cipher The Cipher class is an abstract class that describes the basic interface of any cipher. This is an interface class, i.e. it provides no implementation. Create the Cipher class in a file called Cipher.h according to the UML specification below: Cipher tencodeconst strings string edecodelcanst strings): string A cipher is an algorithm that can encode plaintext, turning it into ciphertext, as well as decode string encode[const string&) This function is abstract and must be overridden by the derived classes. The function will receive plaintext (string) as input, encrypt it, and return encrypted ciphertext (string).
