Additional Setup


This package depends on the @noble/ed25519 and @noble/secp256k1 v2, thus additional steps are needed for some environments:

`ts
// node.js 18 and earlier, needs globalThis.crypto polyfill
import { webcrypto } from 'node:crypto';
// @ts-ignore
if (!globalThis.crypto) globalThis.crypto = webcrypto;

// React Native needs crypto.getRandomValues polyfill and sha256 for @noble/secp256k1
import 'react-native-get-random-values';
import { hmac } from '@noble/hashes/hmac';
import { sha256 } from '@noble/hashes/sha256';
secp.etc.hmacSha256Sync = (k, ...m) => hmac(sha256, k, secp.etc.concatBytes(...m));
secp.etc.hmacSha256Async = (k, ...m) => Promise.resolve(secp.etc.hmacSha256Sync(k, ...m));

// React Native needs crypto.getRandomValues polyfill and sha512 for @noble/ed25519
import 'react-native-get-random-values';
import { sha512 } from '@noble/hashes/sha512';
ed.etc.sha512Sync = (...m) => sha512(ed.etc.concatBytes(...m));
ed.etc.sha512Async = (...m) => Promise.resolve(ed.etc.sha512Sync(...m));
