WebNov 14, 2024 · The AES algorithm is an iterative, symmetric-key block cipher that supports cryptographic keys (secret keys) of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.The below figure shows the high-level AES algorithm: If the data to be encrypted doesn't meet the block size requirement of 128 bits, it must be padded. WebCryptography is the study of concepts like Encryption, decryption, used to provide secure communication, whereas encryption is the process of encoding a message with an algorithm. Cryptography can be considered a field of study, which encompasses many techniques and technologies, whereas Encryption is more of mathematical and …
