- CIPHERS Cryptology, the science of writing and breaking codes and ciphers, uses many ides from mathematics. It is a rapidly expanding profession. Can you decipher the following message, which is written in pig-pen cipher? BOUFJ Brun FELLOF JUJHO3 The Pigpen Cipher is a Substitution Cipher that was used by the Freemasons in the 18th Century. They substituted each letter of the alphabet with a picture. A key to this cipher is formed by placing the letters of the alphabet in "pens" formed by the sales in a tic-tac-toe grid. In the grid the letters are places as shown below. A B J K L S U D E M V W X G H P Q R Y To make the cipher, no dots are used for the letters A through I, only the sides of the pens. We use one dot in each pen for the letters J through R and two dots per pen for S through Z. Write the cipher for each letter below. A- B- C- D- E- F- G- H- |- J- K- L- M - N- P- Q- R- S- T- U- V- w - X - Y- Z- Use the key to decipher the message(picture on the top page):Toy encryption scheme. It encrypts plaintexts that consist of only uppercase letters and the underscore character (27 characters total): ABCDEFGHIJKLMNOPQRSTUVWXYZ_ Note that the underscore character is part of the alphabet and will also be encrypted. A key in this scheme consists of 4 digits, each from 0 to 9. Each digit tells how much to shift one character, that is, change it to the character that many positions later in the alphabet. If the shift goes past '_', then we wrap around to the beginning. The key is applied separately to each group of 4 letters in the message. For example, if the message HI_SALLY is encrypted with the key 2407, the H would be shifted by 2, the I by 4, the underscore by 0, and the S by 7. Then we would start over with the first digit of the key, shifting A by 2, L by 4, and so on. So the ciphertext would be: JM_ZCPLE. Give the encryption of the following messages with the key 2641. a.

- AES (Advanced Encryption Standard) has become the encryption algorithm ofchoice for governments, financial institutions, and security-consciousenterprises around the world. The U.S. National Security Agency (NSC) uses itto protect the country’s “top secret” information. RSA is named for the MITscientists (Rivest, Shamir, and Adleman) who first described it in 1977. It is anasymmetric algorithm that uses a publicly known key for encryption, butrequires a different key, known only to the intended recipient, for decryption.i. Differentiate TWO (2) characteristics between AES and RSA.in C++ language Magic Decoder Ring. A one-time pad is a coding device that uses each character of a key string only once to encode and decode a corresponding character in a message string. Thus, the first character in the key is used to encode and decode the first character in the clear message, the second character in the key is used with the second character in the message, etc. No portion of the key is reused in subsequent messages, making for a very solid coding system, assuming a randomly generated key. You will need to create a class titled MagicDecoderRing that contains the variables and functions needed for obtaining the clear and key texts, encoding and decoding the messages, writing out the encoded message etc. You will need to instantiate an instance of this class in your main function to run your program and encode and decode messages. You need to further break your MagicDecoderRing code down into many small functions that each can be described with a single sentence…In C++ language Magic Decoder Ring.
