WebDec 18, 2024 · However, for chunks of more than 64 bytes, they are split into smaller packets. And if small chunks are sent with less than 1ms in-between, the host will merge them into bigger packets. Your design seems to require that data is grouped, e.g. the group of 720 bytes mentioned in the question. If this is a requirement, the grouping must be ... WebAug 9, 2024 · where 11 bytes is for padding. So for a key size of 512 bits, the maximum length of data that can be encrypted is, 512/8 - 11 = 53 bytes. Again from the book Cryptography Engineering, The solution used almost everywhere is to choose a random secret key K, and encrypt K with the RSA keys. The actual message m is then encrypted …
