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. Webcurve cryptography methods which make use of more advanced mathematical concepts.
