Exactly. The specs for the second version(s) of COMP128 that operators
ended up to adopt have not leaked. Notwithstanding this and depending on
the actual design of the algorithm at hand, an oracle may get us closer to
understanding something more about this.
I'm not suggesting here that the algorithm can be reversed looking at its
images and input quantities. Still...
Cheers,
