crypto-json v2.0.2

crypto-json

Recursively encrypt/decrypt objects selectively by keys.

Installation

$ npm install crypto-json --save

Usage

const cryptoJSON = require('crypto-json')

cryptoJSON.encrypt(object, password, config) => encryptedObject

cryptoJSON.decrypt(encryptedObject, password, config) => object

config (optional)

• algorithm - select any supported by the version of Node you are using (default: aes256)
• encoding - hex, base64, binary (default: hex)
• keys - specify which keys to ignore when encrypting/decrypting (default: [], i.e. encrypt/decrypt everything)

Example

const cryptoJSON = require('crypto-json')
const algorithm = 'camellia-128-cbc'
const encoding = 'hex'

const input = {
  hello: {
    bar: ['hello', 'world'],
    baz: {
      a: {
        b: ['a', {test: 1}]
      }
    }
  }
}

const password = 'some random password'

// keys act like a white list, so for example if you want to encrypt a nested
// key "test" you also need to specify its parent keys,
// i.e. "b", "a", "baz", "hello" in the above input object

const keys = ['hello', 'bar', 'baz', 'a', 'b', 'test']
const algorithm = 'aes256'
const encoding = 'hex'

const output = cryptoJSON.encrypt(
  input, password, {encoding, keys, algorithm}
)
