Condensed matter theory physicist and quantum information expert Sankar Das Sarma has argued in MIT Technology Review that quantum computers remain a very long way away from cracking RSA-based cryptography.
RSA-Cryptography utilizes algorithms, codes and keys to securely encrypt private data without interference from third parties or malicious actors such as hackers. An example of the methodology in crypto is the creation of a new wallet that generates a public address and private key.
