# is-secret

A distributed maintained collection of patterns that indicate that
something probably is secret.

This is useful if you want to filter sensitive values in a data set.

This module uses a very simple algorithm that will not catch everthing.
Use at your own risk.

var isSecret = require('is-secret')

var data = {
  username: 'watson',
  password: 'f8bY2fg8',
  card: '1234 1234 1234 1234' // credit card number
}

Object.keys(data).forEach(function (key) {
  if (isSecret.key(key) ||
      isSecret.value(data[key])) data[key] = '********'
})

console.log(data)
// {
//   username: 'watson',
//   password: '********',
//   card: '********'

_If you need functionality similar to what is shown in this example, I
suggest you take a look at the
[redact-secrets](https://github.com/watson/redact-secrets) module._
