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:controllerIndexController
2、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
