What Is the Advanced Encryption Standard (AES)?

The Advanced Encryption Standard (AES) is a symmetric encryption algorithm established by the U.S. National Institute of Standards and Technology (NIST) in 2001. It is regarded as one of the most secure and efficient encryption methods. AES uses block cipher encryption, processing data in fixed-size blocks (usually 128, 192, or 256 bits) with a secret key of the same length.

AES is widely used in various applications, such as secure file transfer, data storage, and virtual private networks (VPNs), due to its robust security and fast performance. It is considered the gold standard for symmetric encryption and is used worldwide by governments, businesses, and individuals to protect sensitive information.

Implementing AES encryption requires proper key management practices, as the encrypted data’s security relies on the secret key’s confidentiality. Secure key storage, regular key rotation, and strong, unique keys help ensure the overall security of AES-encrypted data.
