comment Why doesn't CTR mode require blocking?
@PaĆ­loEbermann, Right, I understand that AES-256 has a block size of 128 bits. I also understand that we encrypt a 128-bit nonce with AES-256 (which has a 256-bit key, hence its name). What I don't understand is how AES-256 applies 256-bits worth of key to a 128-bit-long block ... but perhaps this is outside of the scope of this question ;-)

@CodesInChaos, When you say "block size", are you referring to the encryption of the nonce with the key? In other words, for AES-256, we use two 128-bit nonces? I'm afraid I don't follow...
