nodejs aes 对称加密

                var 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: '1234567890abcdef', //16位密钥
    iv: 'yunzhifundsproke', //偏移向量
    padding: 'PKCS7Padding' //补全值
}


var aes = {
    /**
     * AES_128_CBC 加密
     * 128位
     * return base64
     */

    encryption: function (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('');
    },
