Sensitive Data Scanner

⚠️ Scanning happens locally in your browser — nothing is uploaded. Still, avoid pasting real secrets; use test data where possible.

Text or code to scan

Detects: emails, Luhn-valid card numbers, AWS keys, GitHub/Slack/Stripe tokens, JWTs, Bearer headers, private keys, SSNs, IBANs and secret-looking assignments. Regex-based — always double-check before publishing.
