> The point is that any pattern in the plaintxt data shows up in encrypted data if you use AES-ECB. No, that's false. ECB reveals repeating plaintext blocks. "F0123456789ABCDEF0123456789ABCDEF" contains a repeating block-length sequence, but would encrypt to three distinct blocks under ECB, because the sequence is not aligned to a block boundary.
