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
