Note: the source file with rules was taken from file

[git-deny-patterns.json](https://github.com/jandre/safe-commit-hook/blob/master/git-deny-patterns.json)

from repo [jandre/safe-commit-hook](https://github.com/jandre/safe-commit-hook) on Dec 2015.



## Motivation



Can you accidentally add `id_rsa` file to your Github? Sure!

But remember, it will be [very hard](https://help.github.com/articles/remove-sensitive-data/) to remove

traces of them later. [Most popular NPM packages have leaked sensitive information by mistake][1].



Wouldn't be easier to never commit files that should not be committed in the first place?

This project is a easy to use CLI or git pre-commit hook filter that will scrape modified or added

filenames to make sure they do not match widely common patterns (`.pem`, etc.)

For example, here is `ban` in action - stopping me from adding NPM registry `_authToken` to

`.npmrc` file

## Install



Add to your project `npm install --save-dev ban-sensitive-files`



## Use



* From the command line `node node_modules/.bin/ban` when you have any staged files

  to check their filenames.



* From NPM script



```json

"scripts": {

  "ban": "ban"

}

```



Then run `npm run ban` to check modified, added or deleted filenames.

You can check ALL repo filenames again by adding command line flag `-f` to form the full command

`npm run ban -- -f`.



* When using from other Git hook projects, for example from [pre-git](https://github.com/bahmutov/pre-git),

  first, add "ban" NPM script command, then add to the `pre-commit` command list



```json

"config": {

  "pre-git": {

    "pre-commit": [

      "npm test",

      "npm run ban"

    ]

  }

}

```



* When using from a CI you probably want to check all files in the repo, not just

the changed ones. Pass `-f` or `--all` option. Example Travis file



```yaml

script:

  - npm run ban -- --all

  - npm test

```



## Use as a module



You can use the checker from another module



```js

var isBanned = require('ban-sensitive-files');

isBanned('path/file/name');

// checks single file, returns true or false

// prints any errors to console.error

isBanned(['name1', 'name2', 'name3']);

// checks list of files

isBanned('file/name', logger);

// use provided logger function instead of console.error

```



## Advanced



To figure out what the script is doing, enable debug logging



    DEBUG=ban npm run ban
