WebMay 24, 2024 · Method. The trick with this challenge is to solve for p and q using the relationships. As the modulus n = p q, the binomial expansion of these powers is simply. as all cross terms will contain a p q = n, and x ⋅ n mod n = 0. If we take each of these expressions to the appropriate powers we obtain. c 1 e 2 = ( 2 p) e 1 e 2 + ( 3 q) e 1 e 2 …

The first step is to obtain n = p 2 q, which we can do by computing: n = gcd ( m 1 2 − c 1, m 2 2 − c 2) by using the oracle to obtain c i from integers m i. Note: there may by other factors, and we actually compute k n for some k ∈ Z. We can ensure k = 1 by computing many m i, c i and taking the gcd many times. daughtry album downloadWebCrypto CTF.
