What is AES 256 encryption algorithm?

A symmetric block cipher algorithm with a block/chunk size of 128 bits is the AES Encryption algorithm, also referred to as the Rijndael algorithm. These distinct blocks are converted using keys that are 128, 192, and 256 bits long. It then joins these blocks to create the ciphertext after encrypting each one separately.
