</span>Internal padding bytes (for alignment to 4 bytes) can be zero to 3.</blockquote><div><br>Any idea what's particularly useful to test here? (does it just assert that the parameter is [0,3] ? Or does it have well defined behavior (returning an error code? doing something else?) outside that range? is any case more interesting than any other - or just a simple loop for [0,Padding] done at some point in the algorithm? Does anything test that the algorithm emitted the right padding?)</div></div></div></div>
