Laravel 5.3 provides a detailed description of the customized encryption service solution, laravel5.3

Preface

This article describes the solution for customizing the encryption service in laravel 5.3. Using the service container in laravel, you can register a custom encryption service (in this example, RSA encryption with long strings is supported ), next let's take a look at the detailed introduction:

Create encryption/Decryption Service

The file address/app/Service/Common/CryptService. php code is as follows:

The following is an example of an RSA Encryption Class that supports long strings written by a user. For custom encryption, you only need to change the code of this file. Other operations are only for dependency injection.

<?phpnamespace 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; }}

Create facades

The file address/app/Facades/CryptFacades. php code is as follows:

<?phpnamespace App\Facades;use \Illuminate\Support\Facades\Facade;class CryptFacades extends Facade{ public static function getFacadeAccessor() {  return 'MyCrypt'; }}

Registration Service

The code for creating a file/app/Providers/MyCryptServiceProvider. php is as follows:

In fact, you can also register in AppServiceProvider, so you do not need to create another MyCryptServiceProvider. php file.

In addition, the AppServiceProvider statement is also available in/config/app. php.

<?phpnamespace 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); }}

Declare in configuration

File address/config/app. php added in providershe and aliases

'providers' => [ \App\Providers\MyCryptServiceProvider::class,],'aliases' => [ 'MyCrypt' => \App\Facades\CryptFacades::class,]

Write a configuration file for the custom encryption/Decryption Service

/Config/crypt. php because the CryptService I wrote is useful in the configuration file, I need to add another configuration file. In actual projects, you can set the configuration file and encryption service class as needed.

<? Php // Based on the laravel root directory. The delimiter should be replaced by the DIRECTORY_SEPARATOR constant instead of the 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,];

Example used in Controller

1. artisan creates the Controller File

php artisan make:controller IndexController

2. Edit IndexController

<?phpnamespace 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. Add a route in/routes/web. php

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

4. browser access verification results
