Yes, I stand by what I said. AES (Rijndael) block cipher operates only on 128-bit blocks, not on data that's divisible by 16-bytes. This is an important distinction. Calling AES used in CTR/CBC/etc. mode without mentioning it at all, "AES" speaks much about the sophistication and cryptographic quality of the guide. That's what I was alluding to.
