laravel 5.3中自定义加密服务的方案详解
前言
本文介绍的是laravel5.3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{
returnfalse;
}
$this->keypath=dirname(dirname(dirname(__DIR__))).$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;
}
publicfunctionmakeKey()
{
$res=openssl_pkey_new($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'=>$this->pubkey];
}
publicfunctionencryptPrivate($data){
$crypt=$this->encrypt_split($data);
$crypted='';
foreach($cryptas$k=>$c){
if($k!=0)$crypted.="@";
$crypted.=base64_encode($this->doEncryptPrivate($c));
}
return$crypted;
}
publicfunctionencryptPublic($data){
$crypt=$this->encrypt_split($data);
$crypted='';
foreach($cryptas$k=>$c){
if($k!=0)$crypted.="@";
$crypted.=base64_encode($this->doEncryptPublic($c));
}
return$crypted;
}
publicfunctiondecryptPublic($data){
$decrypt=explode('@',$data);
$decrypted="";
foreach($decryptas$k=>$d){
$decrypted.=$this->doDecryptPublic(base64_decode($d));
}
return$decrypted;
}
publicfunctiondecryptPrivate($data){
$decrypt=explode('@',$data);
$decrypted="";
foreach($decryptas$k=>$d){
$decrypted.=$this->doDecryptPrivate(base64_decode($d));
}
return$decrypted;
}
privatefunctionencrypt_split($data){
$crypt=[];$index=0;
for($i=0;$iprikey)===FALSE){
returnNULL;
}
return$rs;
}
privatefunctiondoDecryptPrivate($data)
{
$rs='';
if(@openssl_private_decrypt($data,$rs,$this->prikey)===FALSE){
returnnull;
}
return$rs;
}
privatefunctiondoEncryptPublic($data){
$rs='';
if(@openssl_public_encrypt($data,$rs,$this->pubkey)===FALSE){
returnNULL;
}
return$rs;
}
privatefunctiondoDecryptPublic($data)
{
$rs='';
if(@openssl_public_decrypt($data,$rs,$this->pubkey)===FALSE){
returnnull;
}
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
'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
phpartisanmake:controllerIndexController2、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
