This repository contains sample implementation of cryptographic functions specified in draft-goldbe-vrf-01.
| VRF suite | OpenSSL | GnuTLS/Nettle |
|---|---|---|
| EC-VRF-P256-SHA256 | DONE | TBD |
| EC-VRF-ED25519-SHA256 | N/A * | TBD |
| RSA-FDH-VRF | DONE (needs update) | DONE (needs update) |
* OpenSSL supports optimized implementation of the curve, primitives required for VRF are missing.
