WebKey and random number generation. Many security-related functions rely on random number generation, for example, salting a password or generating an initialization vector. An important use of random numbers is in the generation of cryptographic key material. Key generation has been described as the most sensitive of all computer security functions. 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.
