OPRF

Oblivious pseudo-random function using ristretto255.

This is an implementation of draft-irtf-cfrg-voprf-07 using libsodium.

It contains the following primitives (plus all the supporting functions):

• oprf_ristretto255_sha512_Blind - client sends a masked secret input to the server.
• oprf_ristretto255_sha512_Evaluate - server takes the masked secret and evaluates an "element" and sends it to the client.
• oprf_ristretto255_sha512_Finalize - client takes the evaluated "element" and calculates the random output.

Installation

For node.js, use:

npm install @aldenml/oprf

For the browser, use the included dist/oprf.min.js or dist/oprf.dev.js.

Usage

Navigate to https://github.com/aldenml/ecc/tree/master/examples/oprf to see how to use this in both the client and the server. Run:

npm install
npm run app

and open the browser at the url http://localhost:8000.
