Now, let's flip a single bit in the input: Now, let's flip a single bit in the input:
One bit flipped: One bit flipped, and again the corresponding ciphertext:

What about input longer a single block? What about input longer a single block?
Input: Input, and ciphertext:

Notice how the ciphertext doesn't change until the block containing the bitflip is reached. This is a limitation of cipher block chaining. Notice how the ciphertext doesn't change until the block containing the bitflip is reached. This is a limitation of cipher block chaining.
