If e = 241015, employ the low-exponent attack to determine d. please do it by hand and take care to keep many decimal places.) However, there is an important part of this
attack: if she hasn’t intercepted any ciphertexts from Alice and doesn’t already know φ(n) and is simply working with Bob’s (n,e), then how can Eve know when she has succeeded at finding d? (Note: this is cryptography, so please do it in math way)
