9.9 Using a spreadsheet (such as Excel) or a calculator, perform the operations described below. Document results of all intermediate modular multiplications. Determine a number of modular multiplications per each major transformation (such as encryption, decryption, primality testing, etc.). b. Encrypt the message block M-2 using RSA with the following parameters:e 23 and n c. Compute a private key (d, p, q) corresponding to the given above public key (e, n) d. Perform the decryption of the obtained ciphertext 233 x 241 1. without using the Chinese Remainder Theorem, and 2. using the Chinese Remainder Theorem
