--- Comment #1 from Sadoon Albader <sadoon at albader.co> ---
Rough brainstorming:

To implement comprehensive unit tests we need to understand what we're testing,
figure out the normal cases, edge cases, and additional behavior that is
specifically related to SVP64.

I'll organize this list in order of complexity.

numbers are in bytes,
m = message, k = key, h' = received MAC, h = generated MAC 


Message size:

-m[0] is received, nothing to authenticate, exit

- m[16] is received, algorithm needs to process exactly one block and is done.

- m[16*n] is received, algorithm needs to process exactly n blocks using the
same function and is done.

-m[1<n<16] is received, algorithm needs to process leftover data as opposed to
full data (I have to study this a bit more)

-m[17<n] where n%16=/=0 received, algorithm processes n/16 blocks normally and
the last block is processed as leftover.
