Advanced Encryption Standard

Advanced Encryption Standard (AES) is a symmetric encryption algorithm used to protect sensitive data. It is a block cipher that encrypts data in fixed-size blocks of 128 bits using a key of 128, 192, or 256 bits. AES is widely used in various applications such as online transactions, wireless communication, and VPNs. It is considered one of the most secure encryption algorithms available today due to its resistance to various attacks, including brute force attacks. AES operates by performing a series of mathematical operations on the plaintext data and the key, which results in the ciphertext. The decryption process is the reverse of the encryption process, and it requires the same key that was used for encryption.
