To ensure the security of the RSA cryptosystem, it is indeed important to select large prime numbers for the keys computing algorithm. In fact, it is recommended to choose prime numbers that are at least 512 bits in length, and in some cases even larger, such as twice or four times as much. The security

Shor's Quantum Factoring Algorithm is a groundbreaking algorithm that exploits the power of quantum computing to efficiently factor large composite numbers. This algorithm, developed by Peter Shor in 1994, has significant implications for cryptography and the security of modern communication systems. The key idea behind Shor's algorithm lies in its ability to leverage the quantum
