Suppose we have a set of blocks encoded with the RSA algorithm and we don't have the
Question:
Suppose we have a set of blocks encoded with the RSA algorithm and we don't have the private key. Assume \(n=p q, e\) is the public key. Suppose also someone tells us they know one of the plaintext blocks has a common factor with \(n\). Does this help us in any way?
