라라벨 암호화 복호화 (encrypt, decrypt)

config/app.php 설정 파일의 key 옵션을 지정해야 함

php artisan key:generate 명령어를 사용하여 키를 생성.

$val = '123456789';
$val_en = encrypt($val);
$val_de = decrypt($val_en);

echo $val."<br>".$val_en."<br>".$val_de;

또는

use Illuminate\Support\Facades\Crypt;

...

$encrypted_hp = Crypt::encryptString($hp);
//$decrypted = Crypt::decryptString($encrypted);

DB::table('TB_Inbounds')->insert(
   [
      'u_name' => '고객명',
      'u_hp' => $encrypted_hp,
      'u_created_at' => date("Y-m-d H:i:s"),
   ]
);


...


$users = DB::table('TB_Member')
   ->where('u_hp', $encrypted_hp)->first();
    
if($users){
   echo $users->u_name;
   echo Crypt::decryptString($users->u_hp);
                
}

이 암호화 값은 복호화가 되지만 값 자체는 매번 바껴서 DB에 저장하고 검색등에 사용할 수 없음

 

 

 

 

 

비밀번호 비교

// See the password_hash() example to see where this came from.
$hash = '$2y$07$BCryptRequires22Chrcte/VlQH0piJtjXl.0t1XkA8pw9dMXTpOq';

if (password_verify('rasmuslerdorf', $hash)) {
    echo 'Password is valid!';
} else {
    echo 'Invalid password.';
}


$sql_script = 'select * from USERS where username="'.$username.'"';

[CentOS7] 라라벨(Laravel) 비밀번호 해시(암호화, 복호화) 설정하기

 

 

 

 

 

전화번호등 검색에 필요할 필드일 경우 따로 Class를 만들어서 암호화 하면됨
