Secret Scanner

Accidentally committing API keys, database passwords, or authentication tokens to a repository is one of the most common and costly security mistakes developers make. Leaked credentials can be exploited within minutes by automated bots that continuously scan public repositories.

This secret scanner checks your code and configuration files against 20+ curated regex patterns for common secret types: AWS access keys, GitHub personal access tokens, Google API keys, Stripe secret keys, Slack tokens, database connection strings, JWT tokens, private keys, and more.

Most importantly, this tool runs entirely in your browser. Unlike server-based scanners, your code is never uploaded anywhere. This makes it safe to scan proprietary source code, environment files, and production configurations.

How to Use the Secret Scanner

  1. Paste your code, configuration, or environment file into the input editor.
  2. Click Scan for Secrets to run the pattern detection.
  3. Review any findings with severity levels and line numbers.
  4. Rotate any exposed credentials and update your codebase.

Secret Scanner Examples

Before 
const config = {
  AWS_KEY: "AKIAIOSFODNN7EXAMPLE",
  STRIPE: "sk_live_1234567890abcdefghijklmnop"
}
After 
[HIGH] AWS Access Key (line 2): AKIAIОСF...MPLE
[CRITICAL] Stripe Secret Key (line 3): sk_live_...mnop

Frequently Asked Questions

  • Is my code uploaded to a server?

    No. All pattern matching runs locally in your browser using JavaScript regex. Your source code never leaves your device.

  • What types of secrets does it detect?

    It detects AWS keys, GitHub tokens, Google API keys, Stripe keys, Slack tokens, private keys, database URLs, JWT tokens, npm tokens, SendGrid keys, Twilio SIDs, and generic API key/secret patterns.

  • What should I do if it finds a secret?

    Immediately rotate (regenerate) the exposed credential in the respective service's dashboard. Then remove it from your code and use environment variables or a secrets manager instead.

  • Is this a replacement for tools like GitLeaks?

    This is a quick pre-commit check for individual files. For comprehensive repository-wide scanning, we recommend also using GitLeaks, TruffleHog, or GitHub's built-in secret scanning.
