Wistron i4.0 Crypto Utility

This is a wrapper encryption utility of crypto-js.

• Quick Start
• Encrypt
• Decrypt

Quick Start

1. Install package

> npm i wistroni40-crypt

2. Simple Usage

import { Cryptor } from 'wistroni40-crypt';

const cryptor = new Cryptor();
const data = { simple: 'data' };
[data] === cryptor.decrypt(cryptor.encrypt([data])); // true

Encrypt

import { Cryptor } from 'wistroni40-crypt';

// 使用預設的金鑰來測試 (只會加密一次)
// const cryptor = new Cryptor();

// 指定加密金鑰 (可以只給一組；生產環境建議給兩組)
const cryptor = new Cryptor('@PreV_k$y', '@P0sT_k$y');

// 加密回來的資料格式與加密前相同
const data = {
  bar: 'foo',
  aInt: 123,
  hello: 'crypt',
};
const cryptedData = cryptor.encrypt([data]); // 'bar' in cryptedData[0]

// 可以傳入陣列資料
const array = [
  {
    bar: 'foo',
    aInt: 123,
    hello: 'crypt',
  },
];
const cryptedData = cryptor.encrypt(array);

// 可以指定要加密的欄位
const array = [
  {
    bar: 'foo',
    aInt: 123,
    hello: 'crypt',
    nested: {
      hi: 'i am here',
    },
  },
];
const cryptedData = cryptor.encrypt(array, ['hello', 'nested.hi']);
cryptedData[0].bar === 'foo'; // true
cryptedData[0].nested.hi !== 'i am here'; // true

Decrypt

import { Cryptor } from 'wistroni40-crypt';

const cryptor = new Cryptor('@PreV_k$y', '@P0sT_k$y');

// 解密時需要用同一個Cryptor Instance
const array = [
  {
    bar: 'foo',
    aInt: 123,
    hello: 'crypt',
  },
];
const cryptedData = cryptor.encrypt(array);
array === cryptor.decrypt(cryptedData); // true

// 如果有指定欄位加密，解密時一樣要需要指定
const array = [
  {
    bar: 'foo',
    aInt: 123,
    hello: 'crypt',
  },
];
const cryptedData = cryptor.encrypt(array, ['bar']);
array === cryptor.decrypt(cryptedData, ['bar']); // true
