🛡️ Baseline Workflow

Track known secrets that are intentional or false positives:

# Create baseline
secret-scanner baseline .

# The baseline file .secret-scanner-baseline.json captures current findings
# Future scans can reference this to skip known issues

---

⚡ Smart Filtering

The scanner automatically skips:

Category	Skipped
Directories	.git, node_modules, .venv, __pycache__, dist, build, vendor
Binary files	.png, .jpg, .exe, .dll, .pdf, .zip, .tar.gz
Lock files	*.lock
Large files	Files > 1MB
Placeholders	your_api_key_here, changeme, placeholder, example
Comments	Lines starting with #, //, /* (unless --include-comments)

---
