WebAug 3, 2024 · AES-192 encrypts blocks of a 192-bit size. AES-256 encrypts blocks of a 256-bit size. In addition to having different block sizes, each encryption method has a different number of rounds. These rounds are the processes of changing a plaintext piece of data into encrypted data or ciphered text. AES-128, for example, uses 10 rounds, and AES-256 ... WebCryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa. It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. Cryptography not only protects data from theft or alteration, but can also be used for ...
