comment How can rainbow tables be used for a dictionary attack?
@Aurelien I'm not actually sure you can. By output space I was thinking more of combinations such as "upper and lower case alphanumericals", up to 8 characters. This you can map to - but mapping to a given word in the English language is hard (impossible?) to encompass in a function (without as you say incurring a cost for this beyond the cost of storing the function instructions). If anyone knows a way, though, I'd be really interested.

@noloader no worries. I wasn't sure so I clarified just in case - you never know.

comment Should we MAC-then-encrypt or encrypt-then-MAC?
@Clément I have had a go at explaining the difference via a separate question, see crypto.stackexchange.com/q/15485/46 - feel free to ask for clarification there :)
