Hi Guys

That could be done, but unfortunately the limits are lower, it seems
it stops working at around 27-28-bits, you mentioned the other day
that comparisons can only be done in half of the bits, is that true?

Yes, the comparison protocols need some "head-room" in the field. The
bit_length parameter (in options.bit_length) defaults to 32, and this
means that the input numbers to the comparison protocols should be 32
bit at most.


Just a slight elaboration of the above: The implemented protocols require some headroom. But if you really want no headroom then that could be implemented as well. (I'd prefer 1-bit headroom, but that's just because it's only a third the cost.)


Regards,
  Tomas
