Why You Need a Secrets Scanner
In modern development, it's easy to accidentally commit sensitive information like API keys, credentials, or private tokens directly into your source code. Once in a Git repository, these secrets can be exposed to anyone with access, creating a major security vulnerability. A secrets scanner is a crucial tool that helps prevent this by automatically detecting and flagging these exposed credentials before they can be exploited.
Common Use Cases
Pre-Commit Hooks
Run a scanner before every commit to catch secrets before they ever enter your Git history.
CI/CD Pipeline Security
Integrate scanning into your continuous integration pipeline to automatically check all new code changes.
Code Audits
Perform regular scans on your existing codebases to find any secrets that may have been missed in the past.
Log File Analysis
Scan application logs for sensitive data that may have been inadvertently logged during runtime.
Frequently Asked Questions
How does this secrets scanner work?
This tool uses a combination of regular expressions (regex) to detect common secret patterns (like API keys, private keys) and entropy analysis to find strings that look like random, high-entropy tokens. This is a demonstration and not as comprehensive as commercial-grade tools.
Is my code secure when using this online tool?
Yes. All scanning happens entirely within your browser using client-side JavaScript. Your code is never uploaded to a server, ensuring your sensitive information remains private and secure.
What kind of secrets can it find?
The scanner is pre-configured to look for common patterns such as AWS keys, Google API keys, GitHub tokens, private keys (RSA, SSH), and other generic tokens with high entropy. The rules are for demonstration purposes.
What should I do if a secret is found?
If a potential secret is found, you should immediately revoke the key or token with the service provider (e.g., AWS, Google, GitHub). Then, remove it from your codebase and replace it with a secure method for managing secrets, like environment variables or a secrets management service.
Can this tool scan my entire Git repository?
This online version is designed to scan single files or code snippets that you paste into the text area. For scanning entire repositories, you should use dedicated command-line tools that integrate with your local development environment or CI/CD pipeline.
