WebJul 25, 2024 · RSA encryption is not unbreakable. In fact,at least four methods to crack the RSA algorithm over the years have been identified. One of them bypasses encryption altogether by finding the greatest common divisor of the two public keys. Whenever the divisor is not 1, it means that the result is a prime number that can break both public keys.

In cryptography, the RSA problem summarizes the task of performing an RSA private-key operation given only the public key. The RSA algorithm raises a message to an exponent, modulo a composite number N whose factors are not known. Thus, the task can be neatly described as finding the eth roots of an arbitrary number, modulo N.
