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).
