Wraps the secp256k1_ecrecover and secp256k1_ecrecover_batch symbols exported by luxcpp/crypto/secp256k1. The C-ABI header is luxcpp/crypto/include/lux/crypto/secp256k1.h.

Conforms to:

SEC1 v2 §4.1.6 (Public Key Recovery Operation)
EVM Yellow Paper Appendix E (ECREC precompile at 0x...01)
EIP-2 (signature malleability rule: s in lower half of n)

Use

use lux_crypto_secp256k1::{ecrecover, ecrecover_batch};

let pk = ecrecover(&hash, &r, &s, v)?;        // Single recovery
let (pks, statuses) = ecrecover_batch(&inputs)?;  // Batch path

Build

See lux-crypto-keccak/README.md for CRYPTO_DIR / CRYPTO_BUILD_DIR discovery logic.

Test vectors

tests/spec_vectors.rs covers three independently-verified (hash, r, s, v) triples generated by the production eth_keys library, plus batch round-trip and v low-bit recid selection.
