Explain how to customize encryption services in laravel

How to customize encryption service in laravel? This article mainly introduces you to the relevant information about customizing encryption services in laravel 5.3. The introduction in the article is very detailed and has certain reference learning value for everyone to learn or use laravel 5.3. Friends who need it can take a look below. I hope to be helpful.

Preface

This article introduces the solution of custom encryption service in laravel 5.3, using laravel's service container to implement custom encryption service Registration (the example is RSA encryption that supports long strings), let’s take a look at the detailed introduction:

Create encryption and decryption service class

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

The following is an RSA encryption class written by a person to support long strings as an example. If you want to customize encryption, you only need to change it. The code in this file is just fine, other operations are just for dependency injection.

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; } }

Create facade facades

      

      
Registration Service
Create the file /app/Providers/MyCryptServiceProvider.php The code is as follows:
      

In fact, it can also be By registering in AppServiceProvider, there is no need to create another MyCryptServiceProvider.php file
      

And there is usually an AppServiceProvider declaration in /config/app.php
      

      

      

      
State in the configuration
File address/config/app.php Add
      

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

      
to providershe and aliases to write Custom encryption and decryption service configuration file
/config/crypt.php Because the CryptService I wrote uses a configuration file, I need to add another configuration file. In actual projects, you can set up configuration files and encryption service classes as needed.
      

      
 [ '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 Controller file
      
php artisan make:controller IndexController
      

      
2. Edit 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. Add routing in /routes/web.php
      
Route::get('/test', 'IndexController@test');
      

      
4. Browse Server access verification results
