Walkthrough

The change replaces bundled CryptoJS code with shared legacy cryptography logic and platform-specific primitives. Node integrations use the Node implementation, while the Web AES-CBC cryptor uses Noble. Tests cover legacy compatibility and UTF-8 behavior.

Changes: Cryptography Primitive Migration

Layer / File(s)	Summary
Primitive contract and platform implementations `src/core/components/cryptography/primitives.ts`, `src/core/components/cryptography/noble-primitives.ts`, `src/core/components/cryptography/node-primitives.ts`, `lib/core/components/cryptography/primitives.js`, `lib/core/components/cryptography/noble-primitives.js`, `lib/core/components/cryptography/node-primitives.js`, `src/core/components/cryptography/hmac-sha256.js`, `lib/core/components/cryptography/hmac-sha256.js`, `package.json`	Adds byte helpers and Node and Noble implementations of the cryptographic primitives. Removes the bundled CryptoJS files and adds `@noble/ciphers` and `@noble/hashes`.
Shared legacy cryptography behavior `src/core/components/cryptography/legacy-crypto.ts`, `lib/core/components/cryptography/legacy-crypto.js`, `src/core/components/cryptography/index.ts`, `lib/core/components/cryptography/index.js`	Adds `LegacyCrypto` for hashing, encryption, decryption, key and option handling, and IV handling. The shared cryptography entry points extend it and pass Noble primitives.
Platform crypto integration `src/core/components/cryptography/node.ts`, `lib/core/components/cryptography/node.js`, `src/crypto/modules/NodeCryptoModule/legacyCryptor.ts`, `lib/crypto/modules/NodeCryptoModule/legacyCryptor.js`, `src/node/index.ts`, `lib/node/index.js`, `src/crypto/modules/WebCryptoModule/aesCbcCryptor.ts`	Routes Node consumers to the Node-specific cryptography implementation. Replaces CryptoJS operations in the Web AES-CBC cryptor with Noble byte-based encryption and decryption.
Cryptography compatibility validation `test/unit/legacy_crypto_compat.test.ts`, `test/unit/common.test.ts`	Adds tests for legacy padding, UTF-8 edge cases, and static-IV encryption. Updates custom-encryption test helpers to use Node crypto.

Full details: Title check

Explanation

The title "refactor: use noble for crypto" matches the main change. The PR replaces the CryptoJS-based cryptography implementation with a LegacyCrypto base class that uses injected primitives. noblePrimitives, backed by @noble/ciphers and @noble/hashes, is used in the web path. Node and web modules also get new primitives, and the old CryptoJS bundles are deleted. The title is short and specific, though it does not mention the Node primitives or the removal of CryptoJS.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 2 functions across 19 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Full details: Description check

Explanation

The author did not add a pull request description. The check is lenient, but there is no text to assess against the changeset. The title and the file summaries still describe the purpose of the change, so this check cannot be judged on description content.

Resolution

Add a pull request description that summarizes the change. Include why CryptoJS is replaced with @noble/ciphers and @noble/hashes, which modules are affected, and any behavior or compatibility impact for Node and web users.

Keep the Noble compatibility test out of the CommonJS path.

The published Node entrypoint loads ../core/components/cryptography/node, so it does not load the Noble-backed cryptography/index.js. However, test/unit/legacy_crypto_compat.test.ts directly imports that Noble-backed module. The test runs through Mocha with tsx and CommonJS compiler settings. On Node 22.0–22.11, this test can fail with ERR_REQUIRE_ESM.

Run this test in ESM mode or set its test-runtime minimum to Node 22.12. Do not raise the package engine solely for this path, because the published Node entrypoint does not load Noble.
