Tip checklist (authorized only)
- Confirm sample authorization; prefer lab corpora you control.
- Record
exiftool -verbefore capture. - Prefer a short tag subset (
-a -G1or syllabus-approved groups) over dumping every tag when Evidence size matters. - Hash the sample; note the exact CLI.
- Redact GPS, names, emails, device serials, and other PII before sharing Evidence.
- Escalate type ID to file-magic-tips; hex views to hexdump-xxd-tips.
Allowed framing
- Classroom metadata review of student-owned photos/documents/binaries.
- Teaching students to bind ExifTool output to a hashed sample.
- Documenting "no metadata / unsupported format" as valid lab outcomes.
- Comparing ExifTool vs file vs strings as tooling choices under one binder.
Scope we will not cover
- No stalking / doxxing via EXIF.
- No evidence-tampering cookbooks ("wipe GPS to hide a crime").
- No crack/pirate/keygen framing.
- No credential-theft how-tos from embedded comments.
Beginner path (authorized only)
- Install ExifTool from the lab-approved channel; record version.
- Run a short tag dump on one syllabus-approved sample; redact PII.
- Save the redacted excerpt with the exact CLI + hash.
- Optional: type-ID via file/libmagic; printable strings via strings tips.
- Stop at literacy — respect privacy.
Which to pick
- Prefer authorized, versioned, redacted ExifTool Evidence.
- Use file/strings pages when those jobs fit better.
- No privacy-invasion, crack, or credential-theft framing.

FAQ
What is ExifTool in this page's framing?
A metadata reader/writer for many file formats. Use it only on samples you are authorized to inspect (lab corpora, your own media/binaries, courseware).
ExifTool vs file/libmagic vs strings?
ExifTool ≈ structured metadata tags; file-magic tips ≈ type ID; strings-file tips ≈ printable strings. Label Evidence by the tool present.
Can I strip GPS/PII from someone else's photos without approval?
No. Authorization first. Mentions of stealth stripping appear only as refusals when used to hide evidence improperly.
Does this teach privacy invasion / stalking via EXIF?
No. Authorized metadata literacy with redaction — no stalking cookbooks.
Does this teach credential theft from metadata?
No. Redact secrets/PII in Evidence.
