RSA encryption is a widely used method for securing digital data and communications. It relies on the mathematical difficulty of factoring very large numbers into their prime components. In RSA, a public key encrypts data, and a private key decrypts it, ensuring that only authorized parties can access the information. This system underpins many online security protocols, such as secure website connections and digital signatures, making it a cornerstone of modern cybersecurity. The security of RSA depends on the fact that, with current computing power, breaking the encryption by factoring the large numbers involved is practically impossible.
