What you're practicing: password-hygiene and hash-cracking concepts, fully offline against a fictional hash file.
1. Click "Open" to launch the lab.
2. Look at the fictional hash file provided.
3. Run a dictionary-attack style command against it and read the output format carefully.
4. Note which passwords crack quickly -- usually the weak, common, or short ones.
5. Compare a weak password's crack result to a strong one in the same file.
6. Save your session as a practice report.
Tip: the real lesson here isn't the tool syntax -- it's seeing firsthand why "password123" and a 16-character passphrase are worlds apart.
