As shown, flipping even a single bit, affects the entire ciphertext.
#### What about input longer a single block?

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

### What about extreme inputs?
How non-transparent is the cipher with extreme inputs? Even with a super problematic key?:
