aardio封装库) aes和des加解密

前言

昨天那篇文章封装了微软的js引擎，文章里说可以用crypt-js来实现一些常用的加解密算法，但是如果我只是需要使用aes这个算法，确要加载一个js引擎。

这样属实有点累赘了，而且浪费资源。所以这篇文章来写一个C语言实现的AES和DES算法，然后编译成dll封装成库。c语言编译成dll具体我就不说了。

只需要github搜一下aes和des再筛选C/C++，然后增加导出几个函数编译成dll。

使用

aes base64

使用方式很简单，核心就两行代码

// 第一个参数是key，第二个是iv
// 如果是ecb模式，iv可以不传
var aesObj = kicrypt.aes("1234567890abcdef", "1234567890abcdef");
// 第一个参数是需要解密的文本
// 第二个是aes加密的模式，这里实现了ECB/CBC/CFB三种
// 第三个是aes填充的模式，这里实现了Pkcs7Padding/ZeroPadding/NoPadding三种
var result = aesObj.decrypt(text, kicrypt.aes.CBC,kicrypt.aes.Pkcs7Padding);

des

des实现和aes差不多，不过我只实现了CBC和ECB两种模式，并且填充模式默认pkcs7，无法修改。这个代码是几年前写的，估计是当时找的c语言库不支持其他填充模式

des的key和iv都是8位

import console; 
import kicrypt.des;
import crypt.bin;

demo_base64 = function(){
 var t0 = time.tick();
 var text = "NFLYMso61GY=";
 var l = crypt.bin.decodeBase64(text);
    // 如果是ecb模式，iv可以不传
    var desObj = kicrypt.des("12345678", "12345678");
    var result = desObj.decrypt(l, kicrypt.des.DES_CBC);
    console.log("base64解密完成，花费时间: ", time.tick()-t0);
    console.log("basse64解密结果, str: ", result);
    
    var result = desObj.encrypt(result,kicrypt.des.DES_CBC);
    var b64Result = crypt.bin.encodeBase64(result);
    console.log("basse64加密完成，花费时间: ", time.tick()-t0);
    console.log("basse64加密结果, str: ", b64Result);
}

demo_base64()
console.pause(true);

3des

3des的key可以是8位/16位/24位，iv固定8位

import console; 
import kicrypt.des;
import crypt.bin;

demo_3des = function(){
 var t0 = time.tick();
 var desObj = kicrypt.des("app^hbrb:321#@!ewq&^*bnm");
