The content explains the RSA encryption algorithm, which is widely used in digital communications for securing sensitive information and user authentication. It works using a public and private key system, making it asymmetric. The RSA algorithm was developed in 1977 and has become a standard in computer security, used in protocols like SSL/TLS and PGP. The security of RSA is based on the difficulty of factoring large numbers, but it may become vulnerable with the emergence of quantum computers. Other asymmetric encryption algorithms, like ECC, are gaining popularity. RSA has limitations, but post-quantum cryptography is being explored as an alternative. Despite potential challenges, RSA remains a reliable tool for data protection in the present digital age.
