The key to cracking a substitution cipher was first discovered by Arab scholars in the ninth century, but it was not widely known in the West until the fifteenth century. Once frequency analysis of ciphers became widespread, the plain substitution cipher became useless. To fix the problems in the substitution cipher, Blaise de Vigenère invented the strategy of using multiple letter mappings. Rather than using one key for the whole message, Vigenère’s idea was to use a different key for each letter of the message. Using a different key for each letter makes the frequency analysis much more difficult. The key to the Vigenère cipher is the Vigenère square. The rows shown here are simple rotations of the alphabet. Each row in the table shifts the letters of the alphabet one place to the left. When a letter shifts out of the first . The idea is to have the message we want to encode: secretmessage Alongside a word we will use to encrypt: encryptencrypt Plaint text s e c r…

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:…

Let's say you generated RSA keys and you chose p=53, q=41, and the smallest encryption exponent that qualifies for this p and q. (You will have to follow the key generation algorithm to fill in the details.) If someone gives you 343 as the ciphertext they created using your public key, what is the plaintext you get when you use your private key to decrypt? Also note that you can test your answer by encrypting it and making sure you get 343 back.
