Crypto$$Interface Project

Encryption can be described as the process of writing data in a secret code. Decryption is the process of restoring encrypted data to its original state. If you want to send a secret message to someone, you use an encryption algorithm to encrypt the message before you send it$.$ The person receiving the encrypted message must use a decryption algorithm to convert the message to its original contents.

Although not very secure$,$ one of the simplest types of encryption algorithms is the substitution algorithm. A substitution algorithm takes a string and substitutes each character with some other predefined character. For example, each occurrence of the letter $$A$$ might be substituted with the letter $$M$,$ and each occurrence of the letter $$B$$ might be substituted with the letter $$W$.$ To decrypt the message, the substitutions must happen in reverse.

In this programming problem, you will create a project and add the following interface:

interface Crypto $\{$ string Encrypt$($string str$)$; string Decrypt$($string str$)$; $\}$

$807$

The Crypto interface specifies two methods: encrypt and decrypt. The intention of the encrypt method is to accept a string argument and return an encrypted version of that string. The intention of the decrypt method is to accept an encrypted string as its argument and return a decrypted version of that string.

Next, you will write two classes named Cipher$1$ and Cipher$2.$ Each of these classes must implement the Crypto interface. The Cipher$1$ class will use a substitution algorithm to encrypt and decrypt strings, and the Cipher$2$ class will use a different substitution algorithm to encrypt and decrypt s

Do this using C # Visual Studio and Windows forms $-$ no Console.
