README

This directory contains code ported from "Fast Fully Oblivious
Compaction and Shuffling" and "Waks-On/Waks-Off: Fast Oblivious
Offline/Online Shuffling and Sorting with Waksman Networks" by
Sajin Sasy, Aaron Johnson, and Ian Goldberg:

https://crysp.uwaterloo.ca/software/obliv/

with some additional enhancements, such as a multithreaded
implementation of WaksShuffle + Sort and WaksSort.
