hide-secret

Installation

npm install --save hide-secret

Usage

Parameters

var hideSecret = require('hide-secret');
// ...
var maskedObj = hideSecret(obj, opts);
// ...

The opts can be:

  • opts.cloned - clone the input json object for transforming, keep the original object unchanged (default: true).
  • opts.secretFieldNames - a list of secrect field names that need to be hidden (default: ['pass', 'passwd', 'password', 'passphrase', 'secret']).
  • opts.skipped - skip transforming the json object (default: false).

Example

// file: lab/example.js
var hideSecret = require('hide-secret');

var opts = {
  skipped: (process.env.NODE_ENV === 'test')
}

var jsonObj = {
  name: 'myname',
  password: 's3cr3t',
  accounts: [
    {
      role: 'admin',
      username: 'root',
      password: 'a-very-very-very-long-passphrase'
    },
    {
      role: 'API',
      token: 'a-sample-token',
      secret: 'tops3cr3t'
    }
  ]
};

console.log(JSON.stringify(hideSecret(jsonObj, opts), null, 2));

Run the example (without NODE_ENV):

node lab/example.js

The console will display the output as the following:

{
  "name": "myname",
  "password": "******",
  "accounts": [
    {
      "role": "admin",
      "username": "root",
      "password": "*****************..."
    },
    {
      "role": "API",
      "token": "a-sample-token",
      "secret": "*********"
    }
  ]
}

Run the example with NODE_ENV=test:

NODE_ENV=test node lab/example.js

The output will be:

{
  "name": "myname",
  "password": "s3cr3t",
  "accounts": [
    {
      "role": "admin",
      "username": "root",
      "password": "a-very-very-very-long-passphrase"
    },
    {
      "role": "API",
      "token": "a-sample-token",
      "secret": "tops3cr3t"
    }
  ]
}

Benchmark

Clone source code from github, install dependencies and execute lab/benchmark.js script:

git clone https://github.com/devebot/hide-secret.git
cd hide-secret
node install
node lab/benchmark.js

The benchmark script will return the following output:

$ node lab/benchmark.js
=> Benchmark of hideSecret() started ...
 - hideSecret(obj, { cloned: true }) x 60,685 ops/sec ±0.57% (89 runs sampled)
 - hideSecret(obj, { cloned: false }) x 28,421 ops/sec ±1.66% (88 runs sampled)
 - hideSecret(lodash.cloneDeep(obj)) x 19,497 ops/sec ±1.12% (88 runs sampled)
+> Fastest is hideSecret(obj, { cloned: true })
