WebJul 5, 2024 · Solution. To solve this challenge, we use that for the RSA cryptosystem the public and private keys obey. e ⋅ d − 1 ≡ 0 mod ϕ ( n), ⇒ e ⋅ d − 1 = k ⋅ ϕ ( n), k ∈ Z. and Euler's theorem, which states that. gcd ( a, n) = 1 ⇔ a ϕ ( n) ≡ 1 mod n. We have the data t p, t q, e, n which is suffient to solve for p. Using that. t ... WebBabyRSA.
