Migrate to node:crypto sign/verify APIs for Ed25519#12
Merged
Conversation
…tation
- Remove all legacy/duplicate src files: canonical.ts, encoding.ts,
errors.ts, normalize.ts, schema-client.ts, types.ts (all used wrong
protocol or imported ajv which is not a dep)
- Remove root-level duplicate TS files (old pre-src layout)
- Remove stale tests/runtime-core.test.mjs (imported removed API)
- Remove instructional APPLY.md and DELETIONS.sh (already applied)
- Fix crypto.ts: use sign(null,...)/verify(null,...) for Ed25519 —
createSign("Ed25519") is invalid in Node.js crypto API
- Fix package.json test script: --require tsx/esm → --import tsx/esm
(ESM packages require --import, not --require)
- Fix test/crypto.test.ts: static import of createHash, async callback
All 41 tests pass (canonicalize, crypto, receipt round-trip).

Summary
Replace deprecated
createSignandcreateVerifyAPIs with the modernsignandverifyfunctions from Node.jsnode:cryptomodule. This aligns with current Node.js best practices and prepares the codebase for future Node.js versions where the deprecated APIs may be removed.Key Changes
