detect-secrets

A developer-friendly secrets detection tool for CI and pre-commit hooks

About

The detect-secrets npm package is a Node.js-based wrapper for Yelp's detect-secrets tool that aims to provide an accessible and developer-friendly method of introducing secrets detection in pre-commit hooks.

Yelp's detect-secrets is based on Python and requires explicit installation from developers. Moreover, its installation may be challenging in different operating systems. detect-secrets aims to alleviate this challenge by:

1. Attempt to locate Yelp's detect-secrets tool, and if it exists in the path to execute it.

If it fails it continues to:

2. Attempt to locate the docker binary and if it exists it will download and execute the docker container for lirantal/detect-secrets which has Yelp's detect-secrets inside the image.

If this fails as well:

3. Exit with a warning message

--

The above described fallback strategy is used to find an available method of executing the detect-secrets tool to protect the developer from leaking secrets into source code control.

Install

``bash
npm install --save detect-secrets
`

This will expose detect-secrets-launcher Node.js executable file.

Another way to invoke it is with npx which will download and execute the detect-secrets wrapper on the fly:

`bash
npx detect-secrets [arguments]
`

Usage

If you're using husky to manage pre-commit hooks configuration, then enabling secrets detection is as simple as adding another hook entry.

`js
"husky": {
"hooks": {
"pre-commit": "detect-secrets-launcher src/*"
}
}
`

If you're using husky and lint-staged to manage pre-commit hooks configuration and running static code analysis on staged files, then enabling secrets detection is as simple as adding another lint-staged entry.

A typical setup will look like this as an example:

`js
"husky": {
"hooks": {
"pre-commit": "lint-staged"
},
},
"lint-staged": {
"linters": {
"*/.js": [
"detect-secrets-launcher --baseline .secrets-baseline"
]
}
}
`

If you're not using a baseline file (it is created using Yelp's server-side detect-secrets tool) then you can simply omit this out and keep it as simple as detect-secrets-launcher.

Example

To scan the index.js file within a repository for the potential of leaked secrets inside it run the following:

`bash
detect-secrets-launcher index.js
`

Note that index.js` has to be staged and versioned control. Any other plain file that is not known to git will not be scanned.
