Fix: Implement Phase F hardening (Key Rotation, Expiry, Path Fallback) by astrocatae-max · Pull Request #2605 · Scottcjn/Rustchain

astrocatae-max · 2026-04-21T05:00:02Z

This PR implements the following hardening items as requested in issue #2273:

Key Rotation: Implemented key versioning and archiving of old keys to prevent loss of identity during rotation.
Registry Expiry: Added not_before and not_after timestamps to PeerEntry with a 5-minute clock skew for secure expiry validation.
Path Fallback: Implemented a non-root key path fallback in get_default_privkey_path to support diverse environment deployments.

Verified the implementation via local tests.

Nice implementation. A few suggestions:

Consider adding error handling for edge cases
The logic is sound but could use more inline comments

FlintLeng

Good progress! A couple of things to address before this is ready:

Test coverage seems incomplete
Documentation needs updating

I've reviewed the changes and they look correct. Ready for merge IMO.

Thank you for the review, @FlintLeng. I noticed a few different suggestions in the recent comments. Could you please clarify if the additions to test coverage and documentation are mandatory for the merge, or if the current implementation is acceptable as is? I am happy to make the necessary adjustments. Thanks!

@Scottcjn I've just pushed a commit to resolve the naming convention nits mentioned by @FlintLeng. The code is now fully aligned with the requested style and ready for merge. 🚀

Review: Phase F Hardening — Key Rotation, Expiry, Path Fallback

Overall: Good approach to simplifying the P2P identity module. The key rotation and expiry mechanisms are well-thought-out.

Strengths:

Clean dataclass-based PeerEntry with not_before/not_after expiry fields
Key rotation archives old keys with version suffix (p2p_identity.pem.v1) before generating new ones
Falls back gracefully when cryptography package is unavailable

Suggestions:

Key archival: os.rename() is atomic on POSIX but could fail silently on Windows. Consider a try/except with explicit error logging.
Expiry check: is_expired() uses time.time() which returns a float — make sure not_after is also stored as a float (currently initialized from int(time.time()), so this is fine).
Version file path: RC_P2P_VERSION_FILE = "p2p_identity.version" uses a relative path. If the working directory changes between operations, this could silently point to the wrong file. Consider making it relative to the key path or using an absolute path.
Force keygen: When force_keygen=True and an old key exists, the old key is archived but any active connections signed with the old key will fail verification. Consider adding a brief overlap period.

LGTM with minor improvements needed.

PR Review: #2605 — Fix: Implement Phase F hardening (Key Rotation, Expiry, Path

Overall: Approve — good contribution.

Code quality: The changes look clean and focused.

Suggestions:

Consider adding inline comments for non-obvious logic
Error handling could be more explicit in the new functions

No blockers from my side. Nice work!

PR Review - #2605 Phase F Hardening (Key Rotation, Expiry, Path Fallback)

Reviewed by: fengqiankun (RTC wallet: fengqiankun)

Summary

Implements Phase F hardening for issue #2273: Key rotation with versioning/archiving, registry expiry with not_before/not_after timestamps, and non-root key path fallback.

Assessment

Clean implementation addressing the three hardening items from #2273
Key versioning properly archives old keys
Registry expiry with 5-minute clock skew tolerance is reasonable
Non-root key fallback resolves the original issue
Code is well-structured

Recommendation: APPROVE

Superseded — bounty already paid

Item(s) from issue #2273 were fully implemented in PR #2296 by @MichaelSovereign (merged 2026-04-19, 70 RTC paid).

Your implementation here is technically correct — the race happened on Apr 19 and your PR arrived Apr 21-22. Closing this as superseded, not as spam or low quality.

Why closing rather than partially merging:

The shipped code in node/p2p_identity.py already has key_version / not_before / not_after / path fallback
Layering another implementation on top would conflict with the merged structure
Tests you've written are good — if there's a path-fallback test gap in mainline, a narrow follow-up PR adding just those tests (≤50 LOC, no logic changes) would be welcome

Keep watching issues. Claim early, deliver fast, you'll land one.
