SatoshiQaziMuhammed caaa7468bc chore(scure-sr25519): add the source lib/ is built from (#17 )

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/scure-sr25519

SR25519 cryptography for PezkuwiChain with bizinikiwi signing context.

Fork of @scure/sr25519 with PezkuwiChain-specific signing context.

Installation

npm install @pezkuwi/scure-sr25519

Usage

import { getPublicKey, sign, verify, secretFromSeed } from '@pezkuwi/scure-sr25519';

// Generate keypair from 32-byte seed
const secret = secretFromSeed(seed);
const publicKey = getPublicKey(secret);

// Sign message
const signature = sign(secret, message);

// Verify
const valid = verify(message, signature, publicKey);

Difference from @scure/sr25519

index.ts is @scure/sr25519 0.2.0 with three changes:

the signing context is bizinikiwi instead of substrate (BIZINIKIWI_CONTEXT, used by sign and verify), so signatures match PezkuwiChain's runtime;
the two header comment lines name Pezkuwi instead of Polkadot.

Nothing else differs; lib/ is the TypeScript output of index.ts.

Building

yarn build:scure-sr25519   # from the repository root; writes lib/
./scripts/check-scure-sr25519.sh   # CI: lib/ must equal a fresh build
