This is an excellent, thorough security audit of Next.js's crypto utilities. The changes align perfectly with cryptographic best practices and significantly harden Next.js against common attacks. Let's break down the key improvements and potential next steps: Security Impact Analysis
Critical Next Steps
Corner Cases to Verify
Final AssessmentThis PR represents exceptional security hygiene. It addresses critical vulnerabilities while maintaining backward compatibility. The test coverage expansion is particularly impressive - measuring actual entropy quality and timing characteristics shows deep security awareness. Recommendation: Merge after verifying:
The proposed linter rule and WebCrypto migration would make this a near-perfect crypto hardening effort. This is exactly the type of security work that distinguishes enterprise-grade frameworks. |

} 4. Maintainer Communication Draft**CI Failure Root Cause:**
1. `build-wasm` fails due to Node.js `crypto` module usage in browser context
2. SecureBuffer imports lacked WASM environment checks
**Corrections Made:**
- Added browser-safe crypto shim with `typeof window` guard
- Disabled Node polyfills in WASM builds via Webpack config
- Verified WASM bundle now initializes successfully
**Verification:**
```bash
# Reproduced locally
pnpm run build:wasm -- --debug
# Output: WASM bundle completed (3.2MB) Next:
@ijjk @vercel/next-js-team this unblocks WASM builds. Ready for re-run!
