Gents,
Just a minor side observation;
Yes, zero is easy to get right in a standard; but not as easy
to TEST if an implementation is correct during debug stage...
a fixed non-symmetric pattern detects early-on big-endian vrs little-endian
problems and other such problems encountered by developers.
However, other tests nail that down as well, so no big deal.
This is not a request for a change, just a side-observation.

[RH] Two different IVs is easy. The zero IVs were suggested by Carl

That's because one constant IV is as good as another, IMHO, and zero is a
lot easier to get right in a standard.
