AESsalausalgoritmia

AESsalausalgoritmia, often referred to simply as AES, is a symmetric-key encryption algorithm adopted by the U.S. government as a federal standard in 2002. It is widely considered to be one of the most secure and efficient encryption algorithms currently available. AES was developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, and was originally known as Rijndael.

The algorithm operates on fixed-size blocks of data, typically 128 bits, and uses a key of either 128, 192, or 256 bits. The encryption process involves a series of transformations applied to the data blocks, which are repeated multiple times. These transformations include substitution, permutation, and mixing operations, all dependent on the chosen key. The number of rounds varies depending on the key size, with longer keys requiring more rounds for increased security.

AES is a versatile algorithm used in a vast array of applications, including securing wireless networks (WPA2 and WPA3), protecting data in storage devices, and encrypting communications over the internet. Its widespread adoption and rigorous cryptanalysis have established it as a cornerstone of modern cryptography. The algorithm's design prioritizes both security and performance, making it suitable for both high-security environments and resource-constrained devices.
