comment Difference between CBC-MAC and CMAC
@figlesquidge: While the information requested probably is obtainable from Wikipedia, it's not very clearly presented there. IMO, this is a perfectly good reference question, and I'm hoping to see a concise and comprehensive answer summarizing the main differences.

@figlesquidge: Indeed. (Just to be clear, the fact that the link works is not a bug; I've reported the actual bug to SE privately, since it has (minor) security implications.)

comment Why xor is a linear operation but ordinary adding is not
Nitpick: the integers with ordinary addition modulo 256 are not a vector space over any finite field. In fact, they're not a vector space at all, although they are an abelian group, and therefore a module over the ring of integers.
