前言PHP編程
本文介紹的是laravel 5.3中自定義加密服務的方案,利用laravel的服務容器,實現自定義加密服務注冊(示例是支持長字符串的RSA加密),下面來看看詳細的介紹：PHP編程
創建加密解密服務類
PHP編程
文件地址 /app/Service/Common/CryptService.php 代碼如下
PHP編程
下面這個是個人寫的支持長字符串的RSA加密類作為示例,自定義加密的話只需更改這個文件的代碼就好,其它操作只是為了實現依賴注入.PHP編程
<?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;
}
}
創建門面facades
PHP編程
文件地址 /app/Facades/CryptFacades.php 代碼如下：PHP編程
<?php
namespace App\Facades;
use \Illuminate\Support\Facades\Facade;
class CryptFacades extends Facade{
public static function getFacadeAccessor()
{
return 'MyCrypt';
}
}
注冊服務
PHP編程
創建文件 /app/Providers/MyCryptServiceProvider.php 代碼如下:
PHP編程
其實也可以在AppServiceProvider中注冊,就不用另外建個MyCryptServiceProvider.php文件了
PHP編程
而且在/config/app.php中一般也已經有了AppServiceProvider的聲明PHP編程
<?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);
}
}
在配置中聲明
PHP編程
文件地址 /config/app.php 在providershe和aliases中添加PHP編程
'providers' => [ \App\Providers\MyCryptServiceProvider::class, ], 'aliases' => [ 'MyCrypt' => \App\Facades\CryptFacades::class, ]
編寫自定義加密解密服務的配置文件
PHP編程
/config/crypt.php 因為我寫的CryptService有用到配置文件,所以需要再添加個配置文件.在實際項目中,可以根據需要自行設置配置文件和加密服務類.PHP編程
<?php //基于laravel根目錄,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
PHP編程
1、artisan創建Controller文件
PHP編程
php artisan make:controller IndexController
2、編輯IndexController
PHP編程
<?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
PHP編程
Route::get('/test', 'IndexController@test');
4、瀏覽器訪問驗證結果PHP編程
