前段时间写了一篇提高Laravel用户登录，登录失败5次后，锁帐号的功能。

但后面发现，Laravel提供的安全还是不行，数据都是在裸奔，如下图所示：

万一中途xx路由器被入侵了。被人抓到这个包，本来就是http的，又是明文，太不安全了。所以这里做一个加密。

这里知识点比较多，涉及C/C++，OpenSSL、Qt等语言和框架，这里就简单说下思路和贴一些伪代码：

这里我用Qt将OpenSSL库封装成插件，提供下面的API功能：

Get请求：

CJson *RSACipher::getResponse(QMap<QString, QVariant> parament)
{
    CJson *json = new CJson;

    if(parament.contains("cmd")){

        QString cmd = parament.value("cmd").toString();
        RSASecret *rsa = RSASecret::getInstance();
        QList<QVariant> retVec;
        if(cmd == "publicKeys"){

            retVec = rsa->getAllPublicKeys();
        }
        else if(cmd == "privateKeys"){

            retVec = rsa->getAllPrivateKeys();
        }
        else if(cmd == "allKeys"){

            retVec = rsa->getAllKeys();
        }

        json->insertValue("data", retVec);
    }

    return json;
}

Post请求：

CJson *RSACipher::postResponse(QString body)
{
    CJson *json = new CJson;
    QMap<QString, QVariant> map = CJson::JsonToMap(body);
    if(map.contains("cmd") && map.contains("data")){

        RSASecret *rsa = RSASecret::getInstance();
        int  type;
        QString data = map.value("data").toString();
        if(map.contains("type")){

            type = map.value("type").toInt();
        }
        else{

            type = rsa->getLatestType();
        }

        //返回值都是Base64
        QString ret;
        if(map.value("cmd").toString() == "publicEncryption"){

            ret = rsa->publicEncrypt(type, data);
        }
        else if(map.value("cmd").toString() == "privateDecryption"){

            ret = rsa->privateDecrypt(type, data);
        }
        else if(map.value("cmd").toString() == "privateEncryption"){

            ret = rsa->privateEncrypt(type, data);
        }
        else if(map.value("cmd").toString() == "publicDecryption"){

            ret = rsa->publicDecrypt(type, data);
        }

        json->insertValue("type", type);
        json->insertValue("data", ret);
    }
    return json;
}

Qt每小时生成RSA公钥和私钥，并且提供加解密的HTTP接口。

如下RSA公钥：

        }
    ],
    "time": "2022-06-07 15:16:00"
}

然后将这个type和publicKey传给登录前端：

php代码：

$client = new Client();
$data = '';
try{

    $res = $client->request('GET', 'http://127.0.0.1:8080/RSACipher?cmd=publicKeys');
    $data = json_decode($res->getBody()->getContents());
}
catch (GuzzleException $e){

    return response()->json("{}");
}

date_default_timezone_set('Asia/Shanghai');

//拿前一个小时的数据
$sub = date('H') - 1;
return view('auth.login')->with('RSAModel', $data->data[$sub]);

前端代码：

<input type="hidden" id="RSAType" name="type" value="{{$RSAModel->type}}" />
<input type="hidden" id="RSAPublicKey" value="{{$RSAModel->publicKey}}" />

在提交数据前调用JS对其进行RSA加密：

<script src="https://cdn.bootcss.com/jsencrypt/3.0.0-beta.1/jsencrypt.js"></script>
<script type="text/javascript">
        
        //用户登录
        function userLogin(){

            let password = $('#password').val();
            let publicKey = $('#RSAPublicKey').val();

            let encryptRSA = new JSEncrypt();
            encryptRSA.setPublicKey(publicKey);
            let RSAEncrypted = encryptRSA.encrypt(password);

            $('#password').val(RSAEncrypted);
            return true;
        }
</script>

对应的HTML代码如下：

<form method="POST" action="{{ route('login.custom') }}" onsubmit="return userLogin()">

提交时只要带上加密好的password和对应的type。因为C++端是跑马灯的形式，有24个公钥私钥。需要指定是哪一个，才能解密。

后台验证时，当格式验证成功后，对password进行RSA解密。

//密码RSA解密
$rsaClient = new Client();
$rsaDeData = '';
try{

    $data = [
        'data' => $request['password'],
        'type' => $request['type'],
        'cmd' => 'privateDecryption'
    ];
    $res = $rsaClient->request('POST', 'http:/127.0.0.1:8080/RSACipher', [
        'body' => json_encode($data)
    ]);
    $rsaDeData = json_decode($res->getBody()->getContents());
}
catch (GuzzleException $e){

    return response()->json("{}");
}

$passwordDeBase64 = base64_decode($rsaDeData->data);
$request['password'] = $passwordDeBase64;

然后就调用Laravel原始的用户认证就可以了：

$credentials = $request->only('email', 'password');

        if (Auth::attempt($credentials)) {
			......
			......
		}
......

现在来抓下包来看看：
