01 / OVERVIEW

What does it do?

Android application hardening platform for analysis, integrity, anti-tamper and code transformation.

Defensive tooling to help Android applications resist tampering and unauthorized analysis.

02 / CAPABILITIES

Key capabilities

  • APK and DEX structural processing.
  • Integrity, hardening and auditing controls.
  • Rust, Kotlin and JNI components.
  • Repeatable compatibility testing.
03 / MY ROLE

Engineering focus

Architecture, implementation and testing.

TECHNICAL DETAILS

How it is built

Architecture, implementation choices and the current state of the project.

Experimental / beta · development ongoing
01CHALLENGE

What problem does it address?

Build modular Android app defenses that increase the cost of tampering and analysis while preserving compatibility and avoiding claims of unbreakable protection.

02ARCHITECTURE

Architecture and boundaries

01
Analysis and packaging

Rust workspace for APK/DEX structural inspection, profile configuration and artifact reporting.

02
Defensive components

Separate components for transforms, integrity, risk, runtime and hardening. Individual modules do not prove integration in the final command.

03
Integration and release

CLI, Gradle component, compatibility checks and release gates; Phase O audits whether end users actually receive the documented protections.

03TRADE-OFFS

Engineering decisions

  • Apply defense in depth without claiming any security layer is unbreakable.
  • Separate transformation from APK reconstruction and require compatibility tests for changes.
  • Prioritize complete integration of the protection workflow before announcing a stable end-user release.
04VERIFICATION

How it is checked

  • The repository documents unit, property, golden-app, Android compatibility and adversarial regression testing as its quality strategy.
  • The production audit explicitly identifies P0 issues and distinguishes validated engines from the actual protection path.
  • The repository release record keeps the stable version blocked while integration and validation continue.
05LIMITATIONS

Current status and next steps

  • End-to-end B–I protection through the public protect command is not proven; the README and audit explicitly document this blocker.
  • The product remains experimental/beta pending integration, compatibility work, real-artifact tests and release qualification.
  • Validation evidence is not an external security certification or a published resistance benchmark.
