如何在laravel中自定义加密服务？本文主要给大家介绍了在laravel 5.3中自定义加密服务的相关资料，文中介绍的非常详细，对大家学习或者使用laravel 5.3具有一定的参考学习价值，需要的朋友们下面来一起看看吧。希望对大家有所帮助。
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。
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;
}
} 创建门面facades
文件地址 /app/Facades/CryptFacades.php 代码如下：
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
在配置中声明
文件地址 /config/app.php 在providershe和aliases中添加
视野自助系统小型企业版2.0 Build 20050310下载自定义设置的程度更高可以满足大部分中小型企业的建站需求，同时修正了上一版中发现的BUG，优化了核心的代码占用的服务器资源更少，执行速度比上一版更快 主要的特色功能如下： 1）特色的菜单设置功能，菜单设置分为顶部菜单和底部菜单，每一项都可以进行更名、选择是否隐 藏，排序等。 2）增加企业基本信息设置功能，输入的企业信息可以在网页底部的醒目位置看到。 3）增加了在线编辑功能，输入产品信息，企业介绍等栏
'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。
[ '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 IndexController2、编辑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、在/routes/web.php添加路由
Route::get('/test', 'IndexController@test');4、浏览器访问验证结果
