nodejs aes 加解密实例

'use strict';
const crypto = require('crypto');

/
  AES加密的配置 
  1.密钥 
  2.偏移向量 
  3.算法模式CBC 
  4.补全值
 /
var AES_conf = {
  key: getSecretKey(), //密钥
  iv: '1012132405963708', //偏移向量
  padding: 'PKCS7Padding' //补全值
}

/
  读取密钥key
  更具当前客户端的版本vid、平台platform获取对应的key
 /
function getSecretKey(){
  return "abcdabcdabcdabcd";
}

/
  AES_128_CBC 加密 
  128位 
  return base64
 /
function encryption(data) {
  let key = AES_conf.key;
  let iv = AES_conf.iv;
  // let padding = AES_conf.padding;

  var cipherChunks = [];
  var cipher = crypto.createCipheriv('aes-128-cbc', key, iv);
  cipher.setAutoPadding(true);
  cipherChunks.push(cipher.update(data, 'utf8', 'base64'));
  cipherChunks.push(cipher.final('base64'));
  return cipherChunks.join('');
}


/
  解密
  return utf8
 /
function decryption(data){

  let key = AES_conf.key;
  let iv = AES_conf.iv;
  // let padding = AES_conf.padding;

  var cipherChunks = [];
  var decipher = crypto.createDecipheriv('aes-128-cbc', key, iv);
  decipher.setAutoPadding(true);
  cipherChunks.push(decipher.update(data, 'base64', 'utf8'));
  cipherChunks.push(decipher.final('utf8'));
  return cipherChunks.join('');
}


console.log(encryption('aaaaa4')); 
console.log(decryption('VuoXtyUolFyPrK50JnNUdw=='));
