Implement RSA by following the specification in the textbook (also attached at the end of this file). Specifically, the core functions, (a) key generation and (b) encryption/decryption, should be implemented. Pre/post conditions of the functions are as follows: KeyGen (p, q) -> (e, n), (d, n): This function takes as input two primes then outputs public/private keys. There is no restriction for the type of input/output. RSA (k, M) -> This function takes as input a key (private or public) and a message (or a ciphertext) then outputs a ciphertext (or a plaintext) For the simplicity, the following assumptions should be applied: . The KeyGen function takes two primes, both of them are smaller than 100 (no need to check whether they are primes). . The KeyGen function should randomly select the private key 'e' in the range of 3 and A brute-force approach can be used to find a multiplicative inverse (no need to implement extended Euclidean Algorithm). The RSA function does not have to check the type of input, which means we do not care the input is a ciphertext or a plaintext. In case of encryption, RSA function takes as input an integer range from 0 to 256 then outputs a ciphertext in an integer form. It can be extended to take a list of integers, which is optional.
