    });

    return ECB;
}());

module.exports = ECB;

3.使用如下pad-nopadding.js

/*

code.google.com/p/crypto-js/wiki/License
*/
/**
 * A noop padding strategy.
 */
var NoPadding = {
    pad: function () {
    },

    unpad: function () {
    }
};

module.exports = NoPadding;

4.在需要使用的js中 bleUtil.js

var CryptoJS = require('../lib/aes.js');//aes
var CryptoJSMode = require('../lib/mode-ecb.js')//ECB
var CryptoJSNoPad = require('../lib/pad-nopadding.js')//nopadding

//默认 模式/补码方式"
var mode = CryptoJSMode;
var padding = CryptoJSNoPad;

//该出的密钥密码请替换为自己的密钥密码
var key_Int = new Int8Array([1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6]);
var keyBytes = Int8parse(key_Int); // 默认密钥
var pass_Int = new Int8Array([1, 1, 1, 1, 1, 1]);
var passBytes = Int8parse(pass_Int); // 默认密码

//加密
function Encrypt(word) {
    try {
        console.log("需要加密的字符：" + word);
        var command = parseCommand(word);
        command = Int8parse(command);
        // console.log("需要加密的byte：" + command);
        var en = CryptoJS.AES.encrypt(command, keyBytes, { mode: mode, padding: padding });
        // console.log("加密后的base64" + en);
        var rb = en.ciphertext.toString().toUpperCase();
        console.log("加密后的字符" + rb);
        return rb;
    } catch (e) {
        console.log(e);
        return null;
    }
}

//解密
function Decrypt(word) {
    try {
        console.log("需要解密的字符：" + word);
        var encryptedHexStr = CryptoJS.enc.Hex.parse(word);
        var srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);
        var decrypt = CryptoJS.AES.decrypt(srcs, keyBytes, { mode: mode, padding: padding });
        var rb = decrypt.toString();
        console.log("解密后的字符" + rb);
        return rb;
    } catch (e) {
        console.log(e);
        return null;
    }
}

//解析字符命令
function parseCommand(str) {
    var commandBytes = new Int8Array(16);
    var j = 0;
    for (var i = 0; i < 32; i += 2) {
        if (j < str.length) {
            commandBytes[j] = parseInt(str.substr(i, 2),16);
        } else {
            commandBytes[j] = 0;
        }
        j++;
    }
    return commandBytes;
}

//将十进制的命令解析成wordarray
function Int8parse(u8arr) {
    // Shortcut
    var len = u8arr.length;
    // Convert
    var words = [];
    for (var i = 0; i < len; i++) {
        words[i >>> 2] |= (u8arr[i] & 0xff) << (24 - (i % 4) * 8);
    }
    return CryptoJS.lib.WordArray.create(words, len);
}

//解析服务器上的key
function passServerKey(serverKey){
    var keyArray = serverKey.split(",");
    var keyBytes = new Int8Array(16);
    for (var i = 0; i < 16; i ++) {
       keyBytes[i] = keyArray[i];
    }
    return keyBytes;
}

//字符串开头是否是某一串字符
function startWiths(str,eqstr){
    if(str.substr(0,eqstr.length) == eqstr){
        return true;
    }
    return false;
}

module.exports = {
    en: Encrypt,
    de: Decrypt,
    startWiths:startWiths,
}

5.在需要操作的页面js中调用

var bleUtil = require('./util/bleUtil.js');//引入工具包
 //获取token命令
var unlock = "06010101";

var rb = bleUtil.en(unlock);
console.log("加密�后" + rb);

console.log("解密后" + bleUtil.de(rb));
// that.writeChar(deviceId, serviceId, writeChar.characteristicId, rb);
