A Go implementation of the Callisto protocol

Oblivious pseudo-random function (OPRF) protocol functionality implementations based on Curve25519 primitives, including both pure-Python and libsodium-based variants.

A Java library for oblivious pseudorandom functions.

OPRF and VOPRF using ristretto255-SHA512

Easy-to-deploy oblivious pseudo-random function (OPRF) service that allows other parties (typically participants in some secure multi-party computation protocol) to obtain a persistent mask which they cannot decrypt but which they can safely apply (via requests to the service) to private data values of their choice.
