nodejs 核心模块crypto

crypto用于加密解密

'use strict'

var crypto=require('crypto');

var data={age:18}

var key='dt';//定义一个钥匙

var plaintext = JSON.stringify(data);

var cryped = '';

// aes192是一种加密算法，此处也可换成blowfish

var cipher = crypto.createCipher('aes192', key);//加密

cryped += cipher.update(plaintext, 'utf8', 'hex');

cryped += cipher.final('hex');

console.log(cryped);

var decryped='';

var decipher = crypto.createDecipher('aes192', key);//解密

decryped += decipher.update(cryped, 'hex', 'utf8');

decryped += decipher.final('utf8');

console.log(decryped);
