IDPF/Poplar1: Revisit use of bitvec::prelude::Lsb0 order #508

Open divergentdave opened 1 year ago

divergentdave commented 1 year ago

Implementing Encode and Decode for Poplar1AggregationParam is suggesting that Lsb0 may have not been a good choice for bit ordering in various intermediate storage data types. We may want to revisit this in the future to simplify things.

This will be addressed in the spec by cfrg/draft-irtf-cfrg-vdaf#433. We should be able to use Msb0 without any reversing.
