VRF-RFC9381
Description
Rust implementation of VRFs (Verifiable Random Functions) as described in RFC9381.
Compatible with WASM (wasm32-unknown-unknown target). Uses RustCrypto primitives.
Only ECVRF support is baked in as of now, and passes the spec test vectors for it.
If there's enough interest, I can bake in RSA-FDH-VRF support.
As usual, it has not been audited, might be insecure, proceed with caution.
Note: This library uses the curve-25519-dalek fork at https://github.com/iquerejeta/curve25519-dalek for its support of Hash2Curve w/ Elligator encoding (See RFC9380 Section 3-4.2.1), which is needed for VRFs. If you're unhappy with this situation, hold on a bit until this gets merged.

It's still a work in progress when it comes to documentation, so you're basically on your own (or look at the tests) until then.
