WebFeb 9, 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. WebCryptography techniques include confidentiality, integrity, non-repudiation, and authentication. The three types of cryptography are symmetric, asymmetric, and hash values. The many examples of cryptography are DES, AES, RSA, and …
