Detailed Description

abstract base class for message authentication codes.

The main differences between a MAC and an hash function (in terms of programmatic interface) is that a MAC is keyed, and that calculating a MAC for the same message twice may produce two different results so verifying a MAC may not be simply recalculating it and doing a bitwise comparison.
