cardano-crypto 1.0.8

//! Cardano-specific VRF implementation module
//!
//! This module provides a pure Rust implementation that matches Cardano's libsodium
//! VRF implementation byte-for-byte. The implementation is organized into several
//! submodules for maintainability and testability.
//!
//! # Module Organization
//!
//! - `fe25519` - Field element arithmetic for GF(2^255 - 19)
//! - `elligator2` - Elligator2 hash-to-curve mapping
//! - `point` - Edwards point operations and coordinate conversions
//! - `prove` - VRF proof generation
//! - `verify` - VRF proof verification
//!
//! # Compatibility
//!
//! This implementation is designed to produce identical outputs to the C implementation
//! in cardano-crypto-praos/cbits/vrf03/ for all inputs. Every operation has been
//! carefully matched to the reference implementation.
//!
//! # Quick check
//!
//! ```rust
//! use cardano_crypto::vrf::cardano_compat;
//! use cardano_crypto::common::CryptoResult;
//! // Take function pointers to ensure symbols exist and types match
//! let _prove: fn(&[u8;64], &[u8]) -> CryptoResult<[u8;80]> = cardano_compat::cardano_vrf_prove;
//! let _verify: fn(&[u8;32], &[u8;80], &[u8]) -> CryptoResult<[u8;64]> = cardano_compat::cardano_vrf_verify;
//! ```
