WebBlock Cipher vs. Stream Cipher. When discussing symmetric key algorithms, there are two categorical types, block and stream. In fact, you mentioned two in your question: ChaCha20 which is a stream cipher and AES which is a block cipher. The difference comes down to the way the encryption is applied to data (bit by bit or block by block).
