SHPH v0.6.5-dev.1 — Documentation and Evidence Follow-Up

A small factual update to the application: SHPH v0.6.5-dev.1 has now been published as a maintenance, documentation, and validation follow-up.

Patch notes:

  • Fixed TCP session deadline handling so established sessions are not closed by the handshake timeout.
  • Added a regression test covering session lifetime after handshake completion.
  • Expanded public evidence for Windows and Linux native-TUN validation.
  • Added documentation for optional Xray underlay validation and its limitations.
  • Updated benchmark methodology, reproducibility notes, and evidence indexes.

Validation for this release:

  • GitHub Actions passed on Ubuntu and Windows.
  • 316 local workspace tests passed.
  • Clippy, release builds, Criterion benchmark checks, fuzz checks, and cargo audit passed.

This remains a development release. The measurements are local or CI-hosted and should not be interpreted as proof of Internet-wide censorship resistance, anonymity, production readiness, or resistance to state-level DPI. SHPH has not yet received an independent security audit.

The intended Zcash use case remains an optional, self-hosted transport for lightwalletd operators, full-node operators, wallet backends, and community services in environments where direct connectivity is unreliable or blocked. SHPH is complementary to Tor and is not intended to replace Tor or provide an anonymity set.
