License Crack-Me (Reverse the Check)

reverse · easy · +35 XP

Target

GET /api/lab/crackme-101/source (returns Python source of the check function) POST /api/lab/crackme-101/activate body {key} (returns flag iff key passes the check)

Goal: read the source, reverse the function in your head (or with a script), produce a key that satisfies all branches, and submit it. There's no obfuscation — it's a simple chained transform.
