JavaScript aes-128 ECB加密和解密
在之前的做的项目中用了aes-128加密传输的蓝牙连接，之前博客也写了，现在发现写的有些问题，所以重新优化了一下。
下面是一个简单的Dome,(注意，我是使用了自动补全为16位数据，所以解密之后会自动补0成16位数据)
const {CryptoJS} = require('./aes')
//秘钥,一串十六进制的数据，每两个算一组
var key = '11258736322512548864'
//加密
var aesEncrypt = (code)=>{
//秘钥处理
var t = CryptoJS.enc.int8array.parse(hexBuffer(key))
//数据处理
var r = CryptoJS.enc.int8array.parse(hexBuffer(code))
//加密数据,出来是一个数组形式
var n = CryptoJS.enc.int8array.stringify(CryptoJS.AES.encrypt(r,t,{
iv : [],
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.NoPadding
}).ciphertext)
//将数组转化为16进制的字符串形式
return ab2hex(n)
}
//解密
var aesDecrypt = (code) =>{
//秘钥处理
var t = CryptoJS.enc.int8array.parse(hexBuffer(key))
//数据处理
var r = CryptoJS.enc.int8array.parse(hexBuffer(code)).toString(CryptoJS.enc.Base64)
//解密数据,出来是一个数组形式
var n = CryptoJS.enc.int8array.stringify(CryptoJS.AES.decrypt(r,t,{
iv : [],
mode: CryptoJS.mode.ECB,
padding: CryptoJS.pad.NoPadding
}));
//将数组转化为16进制的字符串形式
return ab2hex(n)
}
//数据封装
var hexBuffer = (str)=>{
//字符串不存在，返回一个数组长度为16的0
if (!str) return [...Array(16)].map((_,i)=>{return 0});
//将字符串每两个为一组都转化为10进制的数据，数组长度为16，不够的填0
return [...Array(16)].map((_,i)=>{return parseInt(str.substr(2*i,2),16)||0})
}
//数据解析
var ab2hex = (buffer)=>{
let str = '';
buffer.forEach(item=>{
//判断数据是否小于0，小于0加256
item = item>=0?item:item+256;
//补全，两个为一组
if(item<16){
str += '0' + item.toString(16)
}else{
str += item.toString(16)
}
})
return str
}
代码写的很详细，能直接调用就可以实现加密解密。谢谢观看，有什么问题欢迎联系我。
