laravel 5.3中自定义加密服务的方案详解

前言

本文介绍的是laravel 5.3中自定义加密服务的方案，利用laravel的服务容器，实现自定义加密服务注册(示例是支持长字符串的RSA加密)，下面来看看详细的介绍：

创建加密解密服务类

文件地址 /app/Service/Common/CryptService.php 代码如下

下面这个是个人写的支持长字符串的RSA加密类作为示例，自定义加密的话只需更改这个文件的代码就好，其它操作只是为了实现依赖注入。

config = $config[$select];   $this->private_key_size = $this->config['openssl_config']['private_key_bits'];  } else {   return false;  }  $this->keypath = dirname(dirname(dirname(__DIR__))) . $this->config['path'];  if(!file_exists($this->keypath)){   mkdir($this->keypath,"0777",true);  }  $this->prikey_path = $this->keypath . $this->config['private_key_file_name'];  $this->pubkey_path = $this->keypath . $this->config['public_key_file_name'];  if (file_exists($this->prikey_path))   $this->prikey = file_get_contents($this->prikey_path);  if (file_exists($this->pubkey_path))   $this->pubkey = file_get_contents($this->pubkey_path);  return $this; } public function makeKey() {  $res = openssl_pkey_new($this->config['openssl_config']);  openssl_pkey_export($res, $this->prikey);  file_put_contents($this->prikey_path, $this->prikey);  $pubkey = openssl_pkey_get_details($res);  $this->pubkey = $pubkey['key'];  file_put_contents($this->pubkey_path, $this->pubkey);  return $test = ['prikey' => $this->prikey, 'pubkey' => $this->pubkey]; } public function encryptPrivate($data){  $crypt = $this->encrypt_split($data);  $crypted = '';  foreach ($crypt as $k=>$c){   if($k!=0) $crypted.="@";   $crypted.=base64_encode($this->doEncryptPrivate($c));  }  return $crypted; } public function encryptPublic($data){  $crypt = $this->encrypt_split($data);  $crypted = '';  foreach ($crypt as $k=>$c){   if($k!=0) $crypted.="@";   $crypted.=base64_encode($this->doEncryptPublic($c));  }  return $crypted; } public function decryptPublic($data){  $decrypt = explode('@',$data);  $decrypted = "";  foreach ($decrypt as $k=>$d){   $decrypted .= $this->doDecryptPublic(base64_decode($d));  }  return $decrypted; } public function decryptPrivate($data){  $decrypt = explode('@',$data);  $decrypted = "";  foreach ($decrypt as $k=>$d){   $decrypted .= $this->doDecryptPrivate(base64_decode($d));  }  return $decrypted; } private function encrypt_split($data){  $crypt=[];$index=0;  for($i=0; $iprikey) === FALSE) {   return NULL;  }  return $rs; } private function doDecryptPrivate($data) {  $rs = '';  if (@openssl_private_decrypt($data, $rs, $this->prikey) === FALSE) {   return null;  }  return $rs; } private function doEncryptPublic($data){  $rs = '';  if (@openssl_public_encrypt($data, $rs, $this->pubkey) === FALSE) {   return NULL;  }  return $rs; } private function doDecryptPublic($data) {  $rs = '';  if (@openssl_public_decrypt($data, $rs, $this->pubkey) === FALSE) {   return null;  }  return $rs; }}

创建门面facades

文件地址 /app/Facades/CryptFacades.php 代码如下：

注册服务
创建文件 /app/Providers/MyCryptServiceProvider.php 代码如下:
其实也可以在AppServiceProvider中注册，就不用另外建个MyCryptServiceProvider.php文件了
而且在/config/app.php中一般也已经有了AppServiceProvider的声明
在配置中声明
文件地址 /config/app.php 在providershe和aliases中添加
'providers' => [ \App\Providers\MyCryptServiceProvider::class,],'aliases' => [ 'MyCrypt' => \App\Facades\CryptFacades::class,]
编写自定义加密解密服务的配置文件
/config/crypt.php 因为我写的CryptService有用到配置文件，所以需要再添加个配置文件。在实际项目中，可以根据需要自行设置配置文件和加密服务类。
 [  'path'=>DIRECTORY_SEPARATOR.'storage'.DIRECTORY_SEPARATOR.'rsakey'.DIRECTORY_SEPARATOR,  'private_key_file_name'=>'private_key.pem',  'public_key_file_name' =>'public_key.pem',  'openssl_config'=>[   "digest_alg" => "sha512",   "private_key_bits" => 1024,   "private_key_type" => OPENSSL_KEYTYPE_RSA,  ] ], 'rsa_data'=>[  'path'=>DIRECTORY_SEPARATOR.'storage'.DIRECTORY_SEPARATOR.'rsakey'.DIRECTORY_SEPARATOR,  'private_key_file_name'=>'private.pem',  'public_key_file_name' =>'public.pem',  'openssl_config'=>[   "digest_alg" => "sha512",   "private_key_bits" => 1024,   "private_key_type" => OPENSSL_KEYTYPE_RSA,  ] ]];
在Controller中使用的示例
1、artisan创建Controller文件
php artisan make:controller IndexController
2、编辑IndexController
makeKey();  $short = "abcd";  $long = "   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";  $req['short'] = $short;  $req['short_private_encrypt'] = $crypt->encryptPrivate($short);  $req['short_public_decrypt'] = $crypt->decryptPublic($req['short_private_encrypt']);  $req['long'] = $long;  $req['long_private_encrypt'] = $crypt->encryptPrivate($long);  $req['long_public_decrypt'] = $crypt->decryptPublic($req['long_private_encrypt']);  dump($req);  //dd($req); }}
3、在/routes/web.php添加路由
Route::get('/test', 'IndexController@test');
4、浏览器访问验证结果
