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。


<?php
namespace App\Service\Common;
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:


<?php
namespace App\Facades;
use \Illuminate\Support\Facades\Facade;

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


<?php
namespace App\Providers;

use App\Service\Common\CryptService;
use Illuminate\Support\ServiceProvider;

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' => [
 \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。


<?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


<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
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
