Public Key Encryption:

Q1: If you have access to the public keys n and e, it is possible to reverse the public keys from them. One approach is to factor the value of n to discover p and q, then to determine d by finding a value k such that k(p-1)(q-1) + 1 divides evenly by e, the quotient being d.

Q2: If you have n = 77 and e = 7 for public keys, what are the private keys (n and d)?
