Secret & API Key Scanner
Scan text, configs, Git commits, and codebases to detect leaked AWS keys, Stripe tokens, private keys, and passwords.
- Immediately rotate any exposed credentials
- Use environment variables, not hardcoded values
- Add .env to .gitignore before committing
- Consider using a secrets manager (AWS Secrets Manager, HashiCorp Vault)
How to Use Secret & API Key Scanner
