The package shipped only compiled output, and no repository held its source. lib/ is @scure/sr25519 0.2.0 with three edits made directly in the compiled files: signing context 'substrate' -> 'bizinikiwi' and the two header comment lines. index.ts is upstream's 0.2.0 source with the same edits; compiled with its own tsconfig it reproduces lib/*.js and lib/*.d.ts byte for byte. Only the source maps change, since the hand-edited ones still described upstream's file. - index.ts, tsconfig.json, tsconfig.cjs.json, upstream MIT LICENSE - yarn build:scure-sr25519 rebuilds lib/ - scripts/check-scure-sr25519.sh, run in CI, fails when lib/ is not a build of index.ts - README: what differs from upstream, how to build; it said the context was 'bizinikiwi' instead of 'bizinikiwi'
@pezkuwi/wasm-crypto
WASM cryptographic primitives for PezkuwiChain.
Overview
This package provides WebAssembly-based cryptographic functions used by PezkuwiChain applications, including:
- SR25519 - Schnorr signatures with Ristretto point compression (bizinikiwi signing context)
- ED25519 - Edwards-curve Digital Signature Algorithm
- BIP39 - Mnemonic code for generating deterministic keys
- Hashing - Blake2b, SHA256, SHA512, Keccak, XXHash, Scrypt, PBKDF2
Installation
npm install @pezkuwi/wasm-crypto
# or
yarn add @pezkuwi/wasm-crypto
Usage
import { waitReady, sr25519KeypairFromSeed, sr25519Sign } from '@pezkuwi/wasm-crypto';
// Initialize WASM
await waitReady();
// Generate keypair from seed
const seed = new Uint8Array(32); // your seed here
const keypair = sr25519KeypairFromSeed(seed);
// Sign a message
const publicKey = keypair.slice(64);
const secretKey = keypair.slice(0, 64);
const message = new TextEncoder().encode('Hello PezkuwiChain!');
const signature = sr25519Sign(publicKey, secretKey, message);

Signing Context
This package uses bizinikiwi as the SR25519 signing context, which is unique to PezkuwiChain. This ensures signature incompatibility with other networks for security.
