WebThe length of the two components can vary, but together they must be as large as the block size (e.g. 16 bytes for AES). Alternatively, the counter parameter can be used to pass a counter block object (created in advance with the function Crypto.Util.Counter.new () ) for a more complex composition: an optional, fixed prefix WebData structure alignment is the way data is arranged and accessed in computer memory.It consists of three separate but related issues: data alignment, data structure padding, and packing. The CPU in modern computer hardware performs reads and writes to memory …
We usually generate a random IV and write it in front of the ciphertext. Since it is always 16 bytes for AES-CBC, you can slice it off during decryption. While your self-made padding scheme (multiple "n" characters) works in this case.
