I am going to show you encrypting data in javascript with JSEncrypt library with use RSA keys and decrypting string in Laravel.It is also supported for UTF8 encoding.

Add the this script url your project in html side

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jsencrypt/3.0.0/jsencrypt.min.js"></script>

Basic initialization in JS

      let publicKey= '-----BEGIN PUBLIC KEY----- **** -----END PUBLIC KEY-----';
      const encryptor = new JSEncrypt();
      encryptor.setPublicKey(publicKey);
      const plainText= "This is a encrypting string";
      const encrypted = encryptor.encrypt(plainText);
      #the encrypted string is ready to send your server

Basic initialization in Laravel

      $encryptedData = $request->input('data');
      #save your private key in this path file also you can create path yourself
      $privateKeyFile= file_get_contents(storage_path('app/keys/private.pem'));

      $privateKey = openssl_pkey_get_private($privateKeyFile);
      $encrypted = base64_decode($encryptedData);
      openssl_private_decrypt($encrypted, $decrypted, $privateKey);
      return response()->json(['decrypted' => $decrypted]);

In javascript make mapping json objects with specified keys

Vepa Mirzayev — Tue, 07 Jun 2022 12:56:45 +0000

You have an array of objects what you want to do is map through them and return specific key value pairs in a new array.

The Functions Code SS

1. For example you have specific keys array

2. The JSON Object you want to manipulate

3. Result the mapped JSON Objects



const visibleColumnFields =  ['LicencePlate', 'car', 'CarAttributes', 'ReservationStatus', 'ReservationType', 'CustomerGroupName'];

// The original json objects
      let rows =  [{
        "LicencePlate": "ZPL 524",
        "car": "Opel Corsa",
        "CarAttributes": "Z",
        "ReservationStatus": "İptal Edildi",
        "ReservationType": "Yıllık İç Müşteri",
        "CustomerGroupName": "Dev Test Technology",
        "CompanyName": "İş Geliştirme Müdürlüğü",
        "Zimmet": "Petor Petor ",
        "LocationName": "Test Company Location",
        "EndDateTime": "28.04.2022 00:00",
        "RentDays": "1 Gün",
        "TotalPrice": "350.00",
        "CurrencyType": "Lira",
        "CurrencySymbol": "₺",
        "TotalPriceByCurrency": "350.00",
        "CurrencyRate": "1"
      }];

// Mapping over the objects
      let retwriteRow =   rows.map( function (e) {
        return Object.keys(e).filter((key) => visibleColumnFields.includes(key)).reduce( (cur, key) => {
          return Object.assign(cur, {[key] : e[key]})
        },{})
      });
