Webb9 feb. 2024 · The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext. Webb19 okt. 2024 · Encryption in cryptography is a process by which a plain text or a piece of information is converted into ciphertext or a text which can only be decoded by the receiver for whom the information was intended. The algorithm that is used for the process of encryption is known as a cipher. Webb29 aug. 2024 · In short, AES is a symmetric type of encryption, as it uses the same key to both encrypt and decrypt data. It also uses the SPN (substitution permutation network) algorithm, applying multiple rounds to encrypt data.
