### 利用RSA+AES 前后端对数据进行加密处理 -- 前端实现 ###

*  前言
 *  环境准备
 *  前端使用
 *   *  准备工作
     *  改造AJAX

# 前言 #

上一篇主要将了理论方面，现在来讲讲前端如何设计

# 环境准备 #

需要用到3个js文件

1.aes.js

# 前端使用 #

## 准备工作 ##

在公有js中初始化AES密钥之后获取RAS公钥之后进行加密。  
这样每次加载js都会随机生成AES密钥

//随机获取AES密钥
    var aesPassword = randomString(16);
    var encrypt = new JSEncrypt();
    //公钥
    var RSAPublicKey = "";
    //获取公钥
    getPublicKey();
    encrypt.setPublicKey(RSAPublicKey);
    //加密
    var aesPasswordEncrypt = encrypt.encrypt(aesPassword);

/** AES加密 */
    function encryptAES(aesPassword, word){ 
        var key = CryptoJS.enc.Utf8.parse(aesPassword);
        var srcs = CryptoJS.enc.Utf8.parse(word);
        var encrypted = CryptoJS.AES.encrypt(srcs, key, { mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});
        return Base64.encode(encrypted.toString());
    }
    /** AES解密 */
    function decryptAES(aesPassword, word){ 
        var key = CryptoJS.enc.Utf8.parse(aesPassword);
        var decrypt = CryptoJS.AES.decrypt(Base64.decode(word), key, { mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});
        return CryptoJS.enc.Utf8.stringify(decrypt).toString();
    }
    /* 获取公钥 */
    function getPublicKey(){ 
    	$.ajax({ 
    		url : api+"xxxxxx/xxxxx.do",
    		dataType : "text",
    		async : false,
    		success : function(result){ 
    			RSAPublicKey = result;
    		}
    	})
    	
    }
    /* 随机生成密钥 */
    function randomString(len) { 
        len = len || 32;
        var $chars = 'ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz23456789~!@#$%^&*()_+}{":?><';    /****默认去掉了容易混淆的字符oOLl,9gq,Vv,Uu,I1****/
        var maxPos = $chars.length;
        var pwd = '';
        for (i = 0; i < len; i++) { 
            pwd += $chars.charAt(Math.floor(Math.random() * maxPos));
        }
        return pwd;
    }

## 改造AJAX ##

//通知
    	 $.ajax({ 
    		url : api+"xx/xxxxxx",
    		/* 加密 aesPassword为随机生成的AES密钥 */
    		data : { 
    			type :  encryptAES(aesPassword,2)
    		},
    		async : false,
    		dataType : "json",
    		/* 密文 aesPasswordEncrypt为随机生成的AES密钥进行加密后的密文 */
    		headers: { 
                "Parametric":aesPasswordEncrypt//参数是否加密
            },
    		success : function(data){ 
    		}
    	  });
