WebApr 3, 2012 · Any message longer than 2048 bits represents a number outside this range, and must be encoded in either two blocks or -- if you want safety -- the entire message should be encrypted in a session key. Real-world deployed RSA must protect against … Web2 Answers Sorted by: 22 AES is a block cipher, it works on 16-byte (128-bit) blocks. AES, on its own, can't work with data smaller or bigger than 16 bytes. Smaller data needs to be padded until they're 16 bytes, and larger data needs to be split into 16-byte blocks (and, of course, padded when needed*)
