Web22. 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*) Luckily, there are algorithms that help you achieve just that ...
