Problem

Recall that block ciphers can only encrypt messages of a fixed size, which is called the block size. We know that we can use block chaining modes (e.g. CBC mode) to deal with messages that are longer than the block size, but they don't solve the problem of messages whose lengths aren't an integer multiple of the block size. So how do we make do? Get the instant assignment help. We add padding. For this question, we'll assume that the block cipher we're using is AES-128, which uses 16-byte blocks.
