4. Alice uses the RSA public key modulus n = pq = 23761939. Through espionage, Eve discovers that (p – 1)(q – 1) = 23752000. Determine p, q. Show your work. 5. Encrypt the message 001100001010 using Simplified DES (as defined in the book in section 4.2) and key 111000101. [Hint: After one round, the output is 001010010011.] If you do this by hand, it is sufficient to only do 3 rounds instead of 8 rounds. If you write a program, you should carry out the full implementation. Please provide your code.
