The encryption standard commonly used for securing data is AES (Advanced Encryption Standard). AES is a symmetric encryption algorithm, meaning it uses the same key for both encryption and decryption, making it efficient and fast. Widely adopted for securing sensitive information, AES supports variable key lengths (128, 192, or 256 bits) to enhance security levels. It is used in various applications, including secure file storage, communication protocols, and VPN services. Its effectiveness and strong security features have led to its use as a global standard for encryption.
