網頁Block ciphers encrypt a block of data at a time. For DES, the block size is 8. You can check this with DES.block_size. For ct4, the first 8 bytes that are encrypted are 'abcdefgh', and the next 8 bytes that are encrypted are also 'abcdefgh', so for the output we get 8 encrypted bytes followed by the exact same 8 encrypted bytes. 網頁Carers and Teachers.
