This flow of data over the network requires some sort of security in terms of WebJan 1, 2024 · AES can encrypt data blocks using symmetric keys 128, 192, or 256. Blowfish algorithm takes a variable-length key, ranging from 32 bits to 448 bits, which makes it ideal for more data security. Many attacks recorded against DES with low (56 bits) key size; hence advanced version of DES with higher key size becomes more popular.
