Proof-of-concept implementation of the (V)OPRF protocol in https://datatracker.ietf.org/doc/draft-irtf-cfrg-voprf/

voprf-poc

A selection of proof-of-concept implementations of the OPRF protocol detailed in https://datatracker.ietf.org/doc/draft-irtf-cfrg-voprf/.

Disclaimer

The implementations in this repository have not had been reviewed from a security perspective. They are NOT suitable to be used for anything other than experimental purposes. The implementations are a WIP and subsequently do not implement all drafted functionality yet.

Quickstart

Clone:

git clone [e-mail]:alxdavids/voprf-poc.git --recursive

Implementations

We support some subset of the available VOPRF functionality in the following languages:

• go: A golang v1.12 implementation
• rust: A rust 1.40.0 implementation based on the redox-ecc crate.

All available VOPRF implementations provide interoperable HTTP server & client binaries that can be used to perform the (V)OPRF protocol in the latest version of the draft. See the README.md files in the subfolders for specific instructions on how to run these.
