Securing our data is critical in today's digital environment. This study investigates the possible influence of quantum computers on data security. Research has been initiated by learning about quantum computers and their distinct qualities. These computers, which are driven by quantum bits (qubits), can do numerous jobs at the same time, but they also confront unique problems. The RSA Algorithm has been proposed here which is a key component of modern encryption. To protect our data from normal computers, one can use huge prime integers.The quest then takes to Shor's Algorithm, a quantum innovation designed to decipher complicated codes effectively. We explain how it works and what it means for traditional computing. Author delves into the area of post-quantum cryptography, introducing approaches like lattice cryptography, code-based cryptography, multivariate cryptography and hash-based signatures. These solutions exploit quantum features to guard against quantum computer attacks, albeit they may come with certain trade-offs. This research study emphasizes the constantly changing environment of digital security, emphasizing the importance of adaptive cryptographic systems in an increasingly linked and vulnerable world.
