Encipher each plaintext trigraph code by computing (Plaintext trigraph code)^{Public Key}, dividing the result by the Modulus and taking the remainder.

Okay so the trigraph key is 2723 and the public key is 97 and the modulus is 50657. Literally every calculator i use says the number is too large. I am so confused. These are the numbers what is the problem. Is this the wrong formula the teacher gave us this formula. I am so confused.

Encrypt the given plaintext with the key. Built the key matrix (big size). And show how you get each letter ciphertext (you can do that by making shapes and arrows in key matrix). No need to draw key matric again and again. Show all your work. If you just write cipher text and key matric without showing (shapes and arrow on key matrix) that how you get the ciphertext then your marks will be deducted. key : alphabets plaintext : smartness

In the RSA public-key encryption scheme, each user has a public key, e, and a private key, d. Suppose Alice leaks her private key. Rather than generating a new modulus, she decides to generate a new public key and a new private key. Is this safe? why or why not?

Consider the following code: public class Example { public static void doOp(Op op) { boolean result = op.operation(true, false); System.out.println(result); } public static void main(String[] args) { doOp(new AndOperation()); doOp(new OrOperation()); } } main's output: false true Define any interfaces and/or classes necessary to make this output happen. Multiple answers are possible. You may not modify any of the code in Example.
