liboprf0t64 - 0.1+git20231001.0da3e2b-1.1 main

This library implements the basic OPRF (ristretto255, SHA-512) variant from the
"Oblivious Pseudorandom Functions using Prime-Order Groups" Draft from the IRTF
Crypto Forum Research Group (https://github.com/cfrg/draft-irtf-cfrg-voprf/).
Additionally it implements a threshold OPRF based on "TOPPSS: Cost-minimal
Password-Protected Secret Sharing based on Threshold OPRF" by Krawczyk et al
(https://ia.cr/2017/363).
