A selection of proof-of-concept implementations of the OPRF protocol detailed in https://datatracker.ietf.org/doc/draft-irtf-cfrg-voprf/.
Clone:
git clone git@github.com:alxdavids/voprf-poc.git --recursive
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 a fork of ring for performing ECC operations.
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.
