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。

<?phpnamespace AppServiceCommon;class CryptService{ public $config,$keypath, $prikey_path, $pubkey_path, $prikey, $pubkey , $private_key_size; public function select($select = "rsa_api") {  $config = config("crypt");  if (array_key_exists($select, $config)) {   $this->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; $i<strlen($data); $i+=117){   $src = substr($data, $i, 117);   $crypt[$index] = $src;   $index++;  }  return $crypt; } private function doEncryptPrivate($data) {  $rs = "";  if (@openssl_private_encrypt($data, $rs, $this->prikey) === 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：

<?phpnamespace AppFacades;use IlluminateSupportFacadesFacade;class CryptFacades extends Facade{ public static function getFacadeAccessor() {  return "MyCrypt"; }}

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

<?phpnamespace AppProviders;use AppServiceCommonCryptService;use IlluminateSupportServiceProvider;class MyCryptServiceProvider extends ServiceProvider{ /**  * Bootstrap the application services.  *  * @return void  */ public function boot() {  // } /**  * Register the application services.  *  * @return void  */ public function register() {  App::bind("MyCrypt",CryptService::class); }}

在配置中声明

文件地址 /config/app.php 在providershe和aliases中添加

"providers" => [ AppProvidersMyCryptServiceProvider::class,],"aliases" => [ "MyCrypt" => AppFacadesCryptFacades::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。

<?php//基于laravel根目录，分隔符最好是用 DIRECTORY_SEPARATOR 常量代替return [ "rsa_api" => [  "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

<?phpnamespace AppHttpControllers;use IlluminateHttpRequest;use MyCrypt;class IndexController extends Controller{ public function test(){  $crypt = MyCrypt::select("rsa_api");  $crypt->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
