前言PHP编程

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：PHP编程

创建加密解密服务类
PHP编程

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

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.PHP编程

  1. <?php
  2. namespace App\Service\Common;
  3. class CryptService
  4. {
  5.  public $config,$keypath, $prikey_path, $pubkey_path, $prikey, $pubkey , $private_key_size;
  6.  public function select($select = 'rsa_api')
  7.  {
  8.   $config = config('crypt');
  9.   if (array_key_exists($select, $config)) {
  10.    $this->config = $config[$select];
  11.    $this->private_key_size = $this->config['openssl_config']['private_key_bits'];
  12.   } else {
  13.    return false;
  14.   }
  15.   $this->keypath = dirname(dirname(dirname(__DIR__))) . $this->config['path'];
  16.   if(!file_exists($this->keypath)){
  17.    mkdir($this->keypath,"0777",true);
  18.   }
  19.   $this->prikey_path = $this->keypath . $this->config['private_key_file_name'];
  20.   $this->pubkey_path = $this->keypath . $this->config['public_key_file_name'];
  21.   if (file_exists($this->prikey_path))
  22.    $this->prikey = file_get_contents($this->prikey_path);
  23.   if (file_exists($this->pubkey_path))
  24.    $this->pubkey = file_get_contents($this->pubkey_path);
  25.   return $this;
  26.  }
  27.  public function makeKey()
  28.  {
  29.   $res = openssl_pkey_new($this->config['openssl_config']);
  30.   openssl_pkey_export($res, $this->prikey);
  31.   file_put_contents($this->prikey_path, $this->prikey);
  32.   $pubkey = openssl_pkey_get_details($res);
  33.   $this->pubkey = $pubkey['key'];
  34.   file_put_contents($this->pubkey_path, $this->pubkey);
  35.   return $test = ['prikey' => $this->prikey, 'pubkey' => $this->pubkey];
  36.  }
  37.  public function encryptPrivate($data){
  38.   $crypt = $this->encrypt_split($data);
  39.   $crypted = '';
  40.   foreach ($crypt as $k=>$c){
  41.    if($k!=0) $crypted.="@";
  42.    $crypted.=base64_encode($this->doEncryptPrivate($c));
  43.   }
  44.   return $crypted;
  45.  }
  46.  public function encryptPublic($data){
  47.   $crypt = $this->encrypt_split($data);
  48.   $crypted = '';
  49.   foreach ($crypt as $k=>$c){
  50.    if($k!=0) $crypted.="@";
  51.    $crypted.=base64_encode($this->doEncryptPublic($c));
  52.   }
  53.   return $crypted;
  54.  }
  55.  public function decryptPublic($data){
  56.   $decrypt = explode('@',$data);
  57.   $decrypted = "";
  58.   foreach ($decrypt as $k=>$d){
  59.    $decrypted .= $this->doDecryptPublic(base64_decode($d));
  60.   }
  61.   return $decrypted;
  62.  }
  63.  public function decryptPrivate($data){
  64.   $decrypt = explode('@',$data);
  65.   $decrypted = "";
  66.   foreach ($decrypt as $k=>$d){
  67.    $decrypted .= $this->doDecryptPrivate(base64_decode($d));
  68.   }
  69.   return $decrypted;
  70.  }
  71.  private function encrypt_split($data){
  72.   $crypt=[];$index=0;
  73.   for($i=0; $i<strlen($data); $i+=117){
  74.    $src = substr($data, $i, 117);
  75.    $crypt[$index] = $src;
  76.    $index++;
  77.   }
  78.   return $crypt;
  79.  }
  80.  private function doEncryptPrivate($data)
  81.  {
  82.   $rs = '';
  83.   if (@openssl_private_encrypt($data, $rs, $this->prikey) === FALSE) {
  84.    return NULL;
  85.   }
  86.   return $rs;
  87.  }
  88.  private function doDecryptPrivate($data)
  89.  {
  90.   $rs = '';
  91.   if (@openssl_private_decrypt($data, $rs, $this->prikey) === FALSE) {
  92.    return null;
  93.   }
  94.   return $rs;
  95.  }
  96.  private function doEncryptPublic($data){
  97.   $rs = '';
  98.   if (@openssl_public_encrypt($data, $rs, $this->pubkey) === FALSE) {
  99.    return NULL;
  100.   }
  101.   return $rs;
  102.  }
  103.  private function doDecryptPublic($data)
  104.  {
  105.   $rs = '';
  106.   if (@openssl_public_decrypt($data, $rs, $this->pubkey) === FALSE) {
  107.    return null;
  108.   }
  109.   return $rs;
  110.  }
  111. }

创建门面facades
PHP编程

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

  1. <?php
  2. namespace App\Facades;
  3. use \Illuminate\Support\Facades\Facade;
  4. class CryptFacades extends Facade{
  5.  public static function getFacadeAccessor()
  6.  {
  7.   return 'MyCrypt';
  8.  }
  9. }

注册服务
PHP编程

创建文件 /app/Providers/MyCryptServiceProvider.php 代码如下:
PHP编程

其实也可以在AppServiceProvider中注册,就不用另外建个MyCryptServiceProvider.php文件了
PHP编程

而且在/config/app.php中一般也已经有了AppServiceProvider的声明PHP编程

  1. <?php
  2. namespace App\Providers;
  3. use App\Service\Common\CryptService;
  4. use Illuminate\Support\ServiceProvider;
  5. class MyCryptServiceProvider extends ServiceProvider
  6. {
  7.  /**
  8.   * Bootstrap the application services.
  9.   *
  10.   * @return void
  11.   */
  12.  public function boot()
  13.  {
  14.   //
  15.  }
  16.  /**
  17.   * Register the application services.
  18.   *
  19.   * @return void
  20.   */
  21.  public function register()
  22.  {
  23.   \App::bind('MyCrypt',CryptService::class);
  24.  }
  25. }

在配置中声明
PHP编程

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

  1. 'providers' => [
  2.  \App\Providers\MyCryptServiceProvider::class,
  3. ],
  4. 'aliases' => [
  5.  'MyCrypt' => \App\Facades\CryptFacades::class,
  6. ]

编写自定义加密解密服务的配置文件
PHP编程

/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编程

  1. <?php
  2. //基于laravel根目录,分隔符最好是用 DIRECTORY_SEPARATOR 常量代替
  3. return [
  4.  'rsa_api' => [
  5.   'path'=>DIRECTORY_SEPARATOR.'storage'.DIRECTORY_SEPARATOR.'rsakey'.DIRECTORY_SEPARATOR,
  6.   'private_key_file_name'=>'private_key.pem',
  7.   'public_key_file_name' =>'public_key.pem',
  8.   'openssl_config'=>[
  9.    "digest_alg" => "sha512",
  10.    "private_key_bits" => 1024,
  11.    "private_key_type" => OPENSSL_KEYTYPE_RSA,
  12.   ]
  13.  ],
  14.  'rsa_data'=>[
  15.   'path'=>DIRECTORY_SEPARATOR.'storage'.DIRECTORY_SEPARATOR.'rsakey'.DIRECTORY_SEPARATOR,
  16.   'private_key_file_name'=>'private.pem',
  17.   'public_key_file_name' =>'public.pem',
  18.   'openssl_config'=>[
  19.    "digest_alg" => "sha512",
  20.    "private_key_bits" => 1024,
  21.    "private_key_type" => OPENSSL_KEYTYPE_RSA,
  22.   ]
  23.  ]
  24. ];

在Controller中使用的示例
PHP编程

1、artisan创建Controller文件
PHP编程

  1. php artisan make:controller IndexController

2、编辑IndexController
PHP编程

  1. <?php
  2. namespace App\Http\Controllers;
  3. use Illuminate\Http\Request;
  4. use MyCrypt;
  5. class IndexController extends Controller{
  6.  public function test(){
  7.   $crypt = MyCrypt::select('rsa_api');
  8.   $crypt->makeKey();
  9.   $short = "abcd";
  10.   $long = "
  11.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  12.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  13.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  14.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  15.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  16.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  17.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  18.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  19.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  20.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  21.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
  22.    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
  23.   $req['short'] = $short;
  24.   $req['short_private_encrypt'] = $crypt->encryptPrivate($short);
  25.   $req['short_public_decrypt'] = $crypt->decryptPublic($req['short_private_encrypt']);
  26.   $req['long'] = $long;
  27.   $req['long_private_encrypt'] = $crypt->encryptPrivate($long);
  28.   $req['long_public_decrypt'] = $crypt->decryptPublic($req['long_private_encrypt']);
  29.   dump($req);
  30.   //dd($req);
  31.  }
  32. }

3、在/routes/web.php添加路由
PHP编程

  1. Route::get('/test', 'IndexController@test');

4、浏览器访问验证结果PHP编程
