Final answer:
The Advanced Encryption Standard (AES) is a symmetric encryption algorithm designed to be secure well into the future. It includes varying key sizes, with AES-256 offering high security, including against potential quantum computing threats.
Step-by-step explanation:
The symmetric cryptography algorithm that is designed to be secure well into the future is the Advanced Encryption Standard (AES). AES is widely used for securing sensitive data due to its strength and efficiency. It comes in three key sizes: 128, 192, and 256 bits, where AES-256 is considered highly secure against future threats, including the potential of quantum computing attacks. Symmetric encryption uses the same key for both encryption and decryption, and AES's design ensures that it is a strong choice for confidentiality of data and is expected to remain reliable for many years to come.
The symmetric cryptography algorithm Advanced Encryption Standard (AES) is designed to be secure well into the future. AES is a widely used encryption algorithm that was selected by the U.S. National Institute of Standards and Technology (NIST) to replace the older Data Encryption Standard (DES). It supports key sizes of 128, 192, and 256 bits, making it highly secure and suitable for use in various applications.
