nodejs aes 加解密实例

如下所示：

'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 base
 */
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', 'base'));
 cipherChunks.push(cipher.final('base'));
 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, 'base', 'utf8'));
 cipherChunks.push(decipher.final('utf8'));
 return cipherChunks.join('');
}


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