It will create a project folder with name myblog inside your local system.

To start the development server of laravel – 

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Generate Hash Password Using Hash

We will use Facade Hash class to generate hashed password. We will make use of make() a static method from it.

Hash Facade is linked from here:

use Illuminate\Support\Facades\Hash;

Open any of controller from your application. 

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;

class CustomController extends Controller
{
    /**
     * Write Your Code..
     *
     * @return string
    */
    public function store(Request $request)
    {
        $password = Hash::make("Sanjay Kumar");
        dd($password);
    }
}

We will get output this hashed password –

$2y$10$xtvy7GbXW.DnlP79tmjiQuS6ra1r132vTAcyQvehEeWYDiDZqGr0a

User Password Check with Hash

We will see password check concept between a plain text value and a hashed value.

Let’s say you have this controller. Implement the concept here,

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use App\Http\Controllers\Controller;
use App\Models\User;

class PasswordController extends Controller
{
    /**
     * Updating the password for the user.
     *
     * @param Request $request
     * @return Response
     */

    public function update(Request $request)
    {
        $input = $request->all();

        // User data from database
        $user = User::find(auth()->user()->id);

        // Password check
        if (!Hash::check($input['current_password'], $user->password)) {

            // Password didn't match
        } else {

            // Code to update your old password
        }
    }
}

Concept

Hash::check() returns a boolean value after check. False when value didn’t match and True when values match.

Hash::check($input['current_password'], $user->password)

This value $input[‘current_password’] is a plain text value whereas $user->password is a hashed password value.

<meta http-equiv="content-type" content="text/html; charset=utf-8">Hash::check("some_password", "<meta http-equiv="content-type" content="text/html; charset=utf-8">$2y$10$xtvy7GbXW.DnlP79tmjiQuS6ra1r132vTAcyQveh895YDiDZqGr0a")
