RSA Algorithm in cryptography is based on the fact that you can find and multiply large numbers easily but finding the factor of their product is difficult. Mathematical research estimates that if the key value is 100 digits, it would take attackers more than 70 years to find its value. The...
Quantum algorithms, for instance Shor's algorithm, can quickly factor large numbers, thus making RSA obsolete. Against traditional attacks, with large keys (2048 bit or more) RSA is secure. However, advancement in computing powers may prove to be a challenge to RSA's reliability in the future...
