- for the following sequence of keys, do the following: MBX, EXB, GBX,…, ABX, AXB,…, QXB, YXB, … . 1. Fill in the 3 blanks with strings from your first, second, and third name.Convert the decimal (base 10) number 40 to a binary (base 2) number that has only the digits '0' and '1'. Binary number: (For example, the decimal number 16 is the same as the binary number 10000; the decimal number 13 is the same as the binary number 1101.)Encode the number using the given public key. Encode the number M = 14 using the public key n = 77 and e = 13. Assume you are encoding the number using the RSA cryptosystem. Note: You can use the Modular Exponentiation calculator to help with the calculation. a 46 (mod 77), encoded number = 46 47 (mod 77), encoded number = 47 48 (mod 77), encoded number = 48 d. 49 (mod 77), encoded number = 49
- Convert your name to binary. Begin your first and last name with a capital letter and use lowercase letters for the remaining letters in your name. Put your name in the first column; the ASCII decimal value for each letter of your name in the second column, and the binary number for the decimal equivalent in the remaining columns.

What is the encrypted animal name (enter a string of letters with no spaces)? Decrypt An animal name was encrypted with the scheme described in the previous question (it was encoded with the key 3). The encrypted animal name is pduprw .What is the animal name?Here is the assignment Write a program that prints the multiplication table but inserts a randomly generated incorrect value between 1 and 50 into a cell whose row and column are randomly selected. Make sure the program does insert an incorrect value. For example, if row and column of 3 and 4 are randomly selected, keep generating a random number to print for that location until it's not the right value of 12. Then, ask the user to tell where in the table the incorrect number is located by entering the row and column of the incorrect number. Print whether the user was right or not. If he or she was right, ask for and read the correct value; if not, the program must give the correct location and the correct number. My main issue: is how to set up the multiplication table? I've only learned the basics in C++ (loops and if statements).
- Alice and Bob are two fugitives from justice. Alice sent Bob an encrypted message to inform him about her following secret meeting location. As a cryptanalyst, it is your mission to help the police in decoding the message that contains the room number and the hotel name. Alice’s SECRET MESSAGE IS: 7F7F Norzut jkgjykg Use Cryptool to decrypt the secret message using Caesar cipher. Assume the following: 1. The value of the first alphabet is zero 2. Alphabet set includes: numerals, uppercase, and lowercase letters of the English language 3. Try keys from 0-10 until you find the correct key. a. What is the secret message? b. What key did you use to decrypt it c.

- A company wants to transmit data over the telephone, but it’s concerned that its phones may be tapped. All of its data is transmitted as four-digit integers. It has asked you to write a script that will encrypt its data so that the data may be transmitted more securely. Your script should read a four-digit integer entered by the user in a prompt dialog and encrypt it as follows: Replace each digit by (the sum of that digit plus 7) modulus 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then output HTML5 text that displays the encrypted integer. In HTML and JavaScriptexample: use the above key, if the letter "a" appeared in the message, it would be replaced with "g" since "g" in the adjacent letter. Return the encrypted message.
