In laravel Authtication Process I want to encrypt the email field in the users table(I have used Crypt::encrypt()). On doing so, the Login process fails. I have to validate encrypted email when login. Can someone help me out?


if i did understand your problem well, a good way to resolve it is using the decorator pattern! and since Laravel provides a way to create middlewares easily, we can use them as decorators.

what you need to do is to add a middleware named encryptEmails and as we know, a middleware can have access to the request object! what we need to do now is to retrieve the email value from the request and change it by encrypting it.

of course you must include this middleware on your login route.

using this approach, you won't need to change the content of the built-in authentication class.

here is a code of the middleware's handle function ( i am not sure about the class or the method that encrypts the email ) :

public function handle($request, Closure $next)
{
    $request->email = Crypt::encrypt($request->email)
    return $next($request);
}

you can check this link to get more information about middlewares in Laravel : https://laravel.com/docs/5.7/middleware

Email Verification - Laravel, For the Authtication Process I want to encrypt the email field in the users table. On doing so, the Login process fails. I think I should be able to m. If this value is not properly set, all values encrypted by Laravel will be insecure. Using The Encrypter Encrypting A Value. You may encrypt a value using the encrypt helper. All encrypted values are encrypted using OpenSSL and the AES-256-CBC cipher. Furthermore, all encrypted values are signed with a message authentication code (MAC) to


In this case, you should allow a user to log in by using a username. Override the username() method in LoginController:

public function username()
{
    return 'username';
}

If you still want to use email for authentication, you'll need to load all the users and then check each user's decrypted email which is a bad idea if you have many users registered.

$users = User::all();
foreach ($users as $user) {
    if ($request->email === decrypt($user->email) && \Hash::check($request->password, $user->password)) {
        auth()->login($user); // Login the user if email and password are correct
        break; // Exit from the foreach loop
    }
}

You can also chunk the data.

Again, this solution is ok only for a small number of registered users.

Validate encrypted, When I use Auth::attempt() it will not validate the user. I have tried sending both an encrypted and unencrypted version of the email into the� Laravel - Encryption - Encryption is a process of converting a plain text to a message using some algorithms such that any third user cannot read the information.


I have used the below code in LoginController and worked for me in Laravel 5.6,

public function attemptLogin(Request $request) {
    $users = User::all();
    $isUserValidated=false;
    $field = $request->username;
    foreach ($users as $user) {
        try { // required if the field is not encrypted
            // login using username or email
            if (($field === Crypt::decryptString($user->email) || $field === Crypt::decryptString($user->username)) && \Hash::check($request->password, $user->password)) {
                $isUserValidated=true;
                $this->guard()->login($user,false);
                break; // Exit from the foreach loop
            }
        } catch (DecryptException $e) {
            //
        }
    }
    return $isUserValidated;
}

The command used to generate the key in Laravel is shown below - php artisan key


I think it's important to be able to encrypt the email for login. The problem with Laravel is that it always uses a different initialization vector.

To work around this problem, you can create two methods that use a fixed initialization vector. Then you do not have to loop through all users. You are able to compare the email from request with the database records.

The email must always be decrypted when reading from model. When saving, it must always be encrypted. If you use a unique rule and an email rule for validation, you have to do the validation of the user data in two steps. First the rule Email to validate the format, then Encrypt the passed email and then validate by rule unqiue.

I hope I have been able to help a little.

Note: This is not a ready-made solution, just a code example as an idea. If you try this solution, you need to take care about the password broker and password reset.

/** 
  * Get a new initialization vector 
  * Store this initialization vector in your app-config (/config/app.php)
  **/
function getNewIv() :string
{
    return openssl_random_pseudo_bytes(16);
}

/** encrypt **/
function encryptEmail(string $email): string
{
    $cipher = config('app.cipher', 'AES-256-CBC');
    $key = config('app.key');
    $iv= config('app.iv');

    $encrypted = openssl_encrypt($email, $cipher, $key, 1, base64_decode($iv));
    return base64_encode($encrypted);
}


/** decrypt **/
function decryptEmail(string $email): string
{
    $data = base64_decode($decryptString);
    $cipher = config('app.cipher', 'AES-256-CBC');
    $key = config('app.key');
    $iv= config('app.iv');

    return openssl_decrypt($data, $cipher, $key, 1, base64_decode($iv));
}
