The chef is getting bored with the recent lockdowns caused by the coronavirus epidemic. After some time he started learning cryptography. He is very excited to see the different types of keys used in cryptography and decides to invent a new type of key. First, Chef created a sequence of integers A1,A2,...... An that lie between 1 and M inclusive. After many sleepless nights, he decided that his key would be the LCM of this sequence, but he is not satisfied - he wants to make his key as big as possible. To do this, he wants to append exactly one more integer to the sequence. This integer must also be between 1 and M, inclusive. Help the chef to maximize the key. Find the integer that Chef should append to the sequence so that the key (LCM of the elements of the resulting sequence) is as large as possible. If there are multiple solutions, choose the smallest of the integers to connect that maximizes the LCM.Input Note: please answer this in java language only. 1 32 212 Output 1

The Lingala Language of Republic of Congo has 35 letters. Consider an Affine cipher, which encrypts each letter according to the rule: C=(p×k1+k2) mod 35. Here C, p, k1, and k2 are each members in the range 0 to 34, where C represents the ciphertext letter, p the plaintext letter, and k1 and k2 are constant keys. How many possible keys does this affine system have? Explain in details.
Your task is to design automated solvers for the shift and Vigenere ciphers. You must use C as the under- lying programming language, in order to get prepared for the following labs. Each solver should be completely automated, i.e., upon reading a text ,l.e. containing the target ciphertext (given as command-line argument), it should print the encryption key and the decrypted plaintext without any user interaction. Test your code on the following ciphertexts, and answer these questions: 1. What is the key of the cipher? 2. What is the decrypted plaintext?Shift Cipher - Decrypt the following ciphertext:…
Suppose you’re consulting for a bank that’s concerned about fraud detection, and they come to youwith the following problem. They have a collection of n bank cards that they’ve confiscated, suspectingthem of being used in fraud. Each bank card is a small plastic object, containing a magnetic stripe withsome encrypted data, and it corresponds to a unique account in the bank. Each account can have manybank cards corresponding to it, and we’ll say that two bank cards are equivalent if they correspond to thesame account.It’s very difficult to read the account number off a bank card directly, but the bank has a high-tech “equivalence tester” that takes two bank cards and, after performing some computations, determines whether theyare equivalent.Their question is the following: among the collection of n cards, is there a set of more than n/2 of themthat are all equivalent to one another? Assume that the only feasible operations you can do with the cardsare to pick two of them and plug them…
In a special case of a permutation cipher, we take a message, M, and write its letters in an s× t table, in a row-major fashion, and then let the ciphertext be a column-major listing of the entries in the table. For example, to encrypt the message ATTACKATDAWN, using a 3 × 4 table, we would write the message as ATTA CKAT DAWN and then write down the ciphertext as ACDTKATAWATN. The secret key in this cryptosystem is the pair (s, t). How is decryption done in this cryptosystem? Also, how hard would it be to attack this cryptosystem using a ciphertext-only attack?

kindly do it ASAP Write a code to implement the combination of RSA and AES algorithms. In your implementation, first the RSA will be used to encrypt the secret key for sending from Alice to Bob. On the other hand, the AES will be used for encryption and decryption of long messages between the Alice and Bob. Remember in such type of combination, first the Bob will generate its public and private keys and share its public key with the Alice. The Alice encrypt the short message (secret key for communicating the long messages) using RSA and send it to the Bob. Then Bob decrypts the short message (secret key for communicating the long messages) using its private key and found the short message (secret key for communicating long messages). After that both Alice and Bob use this same secret key for the encryption and decryption of long messages.

(do completely) Question 3 One way to solve the key distribution problem is to use a line from a book that both the sender and the receiver possess. Consider the following ciphertext: B G L C J J Y Y N U D N T G T The key used to encrypt the original message is derived from the first letter of the first four words in the first sentence of The Hunt for the Red October, written by Tom Clancy. “Captain First Rank Marko Ramius of the Soviet Navy was dressed for the Arctic conditions normal to the Northen Fleet submarine base at Polyarnyy.” (Hint: The encoder has removed the blanks between the ciphertext. The key used here might not be a meaningful English word. However the plaintext is a meaningful English phrase). (a) Retrieve the key. (b) Retrieve the whole plaintext.
