SK Checker Full scanned repositories, environment files, logs, and build artifacts. It used pattern matching for common secret formats (API keys, RSA private keys, AWS secret access keys), entropy checks to flag high-entropy strings, and contextual rules to reduce false positives — for example, ignoring keys inside clearly labeled test fixtures. It prioritized findings by risk level and suggested remediation steps.

– The SK Checker sends a test API call to Stripe, usually:
Remember: the line between legitimate testing and illegal activity is clear. Stay on the right side of that line, and use your technical knowledge to build, protect, and educate—not to exploit.
