This library comes with pre-compiled bindings for most platforms. You can check current support in releases. If your platform is not supported, bindings will be compiled from source as a best effort with node-gyp.
import crypto from "crypto";
import {SecretKey, verify, BLST_CONSTANTS} from "@chainsafe/blst";
const msg = Buffer.from("sample-msg");
const sk = SecretKey.fromKeygen(crypto.randomBytes(BLST_CONSTANTS.SECRET_KEY_LENGTH));
const pk = sk.toPublicKey();
const sig = sk.sign(msg);
console.log(verify(msg, pk, sig)); // true
This library has a hardcoded configuration compatible with Eth2.0 spec:
