Allowed framing
- Converting your lab DEX to JAR for a Java viewer pipeline.
- Scripting d2j-* helpers inside an authorized CI job.
- Comparing fork output with Enjarify/jadx on owned APKs.
Scope we will not cover
- No exploit PoC cookbooks.
- No “auto-crack commercial APK protectors” framing.
- No scanning third-party stores without authorization.
Beginner path (authorized only)
- Download dex-tools-2.4.38.zip from ThexXTURBOXx/dex2jar Releases (or the Maven artifacts your build pins).
- Prefer a disposable lab VM; keep the zip SHA-256 in notes.
- Start with a tiny APK/DEX you compiled; run the documented d2j-dex2jar (or successor script name in that zip) on that file only.
- Open the JAR in a viewer you trust; escalate to jadx for source-oriented reading.
- Record fork tag 2.4.38 beside case hashes — do not silently mix pxb1988 SNAPSHOT builds.
- Use dex2jar 2.4.38 when your lab wants the d2j tool suite on authorized samples.
- Prefer jadx for most human APK reading.
- Refuse exploit-PoC framing.

FAQ
What is dex2jar?
dex2jar is a suite of tools for working with Android .dex and Java .class/.jar files, historically used as a DEX→JAR bridge before opening results in Java viewers.
Which version / fork is cited?
Cite the actively released fork ThexXTURBOXx/dex2jar 2.4.38 (published 2026-07-22 UTC; Maven Central de.femtopedia.dex2jar). The original pxb1988/dex2jar tree is historical — prefer the fork's Releases zip (dex-tools-2.4.38.zip) unless your lab pins otherwise (checked 2026-10-24).
What license applies?
Apache License 2.0 (project / Maven metadata; checked 2026-10-24).
Enjarify/jadx or dex2jar?
Prefer jadx for APK→Java source-oriented reading. Prefer Enjarify when you want that translator specifically. Prefer this dex2jar fork when your lab already scripts d2j-* tools or needs its JAR/DEX utilities on authorized samples.
Does this teach writing exploits?
No. Authorized research and education only — BinBench will not supply exploit PoCs or DRM bypass recipes.
