Definition of Laravel Hash
Hashing is the method to transform the character string to a short constant value or it is a key to indicate the original string. The hash function in Laravel gives the secured method to save the passwords in the hashed way which is a shorter way. The hashing function in Laravel provides Argon2 hashing and Bcrypt to save the password of the user. If the user is working on a Laravel application, then Bcrypt is used to register and authenticate in a default method. In this article, the function, implementation, and configuration of hashing operation in Laravel are explained in brief.
What is Laravel Hash?
In simple terms, hashing is used as an algorithm or function to map the object data to represent the integer value. The hash function is also used to slender the searches when locating the items of these objects on the data map. For example, developers used to store the data in the hash table, working on the customer record which is in the form of value pairs and keys. Hashing is the method to transform the character string to a minimum constant value or it is similar to a key that directs the actual string. Laravel hash is used to save the password using the hashing process. It uses Argon2 and Bcrypt methods to store the user passwords in laravel hash. If the user starts to work on the application, the starter kit starts to operate and by default, Bcrypt is used to authenticate and register.
Uses of Laravel Hash
Bcrypt is the standard method to hash the passwords, which has a flexible work factor. It signifies that the time taken to generate the hash process can be maximized when the power of the hardware is increased. When hashing the passwords, it works slower and it is advisable to work in that way. As long as the algorithm consumes to hash the passwords, it will take maximum time for hackers to generate rainbow tables. So longer the process, effective is the hashing and security. All the possible hash values in the string are used at the time of brute force attacks when working in the application. The standard hash driver in the application is configured in config/hashing.php located in the configuration file. It is now mostly used in supported drivers like Argon2 and Bcrypt and can also be applied in Argon2id variants and Argon2 variants.
The hashing passwords can be called with the make method on the hash table. It is used to adjust the Bcrypt work factor. If the user is working on the Bcrypt algorithm, then the make technique is used to achieve the work factor in the algorithm using the round methods. And by default, the work factor is controlled by Laravel and it is accepted for most applications.
$ hashed = hash: make(password, [ "rounds" -> 10,] );
If the user is working on the Argon2 algorithm, the make technique enables the user to control the work factor of the algorithm using time, thread functions, and memory. However, the standard values are managed in Laravel are implied to most of the applications.
To verify the password that matches the hash value is done by check method. The hash façade enables the user to ensure that the given standard-text string belongs to the given hash.
if ( Hash:: check ('plain-text', $hashed Password))
// If the password matches...
If the user wants the passwords to be rehashed then he should imply needsrehash technique. So if the user works on a hash façade he is enabled to decide the work factor in the hash function has changed till the password was hashed. Few applications choose to execute this check at the time of the authentication process in the application.
If (Hash:: needsRehash ($hashed) )
$hashed = Hash:: make('standard text');
The user can also create new hashed passwords in laravel by using the Bcrypt option. The syntax to Bcrypt is $password = Hash:: make (‘password’);
It creates the hashed password in the model or controller, then the user can choose it. If the user submits the password via the form with the help of the POST method, then he can hash the password with the below syntax
$ password = Input:: get ( 'password form field'); // password is in form field
$hashed = Hash:: make ($password);
How to use password laravel hash?
The variable $hashed is comprised of the hashed password where the data can be retrieved from the form which is further validated and again hashed and saved in the database.
- In Laravel 5. Version the user can use the below syntax, $ password = bcrypt (‘name 1’);
- The other method is to use the artisan tinker in the command prompt.
- Open the command prompt window and navigate to the projects present in the root directory.
- Navigate to the concerned directory by typing in the search window.
Cd <name of the directory>.
Echo hash:: make ('some string name');
- It shows the hashed password in the console. Now the user can copy the required data. The laravel hash gives the secured Bcrypt hashing method to include the space to save the user passwords. If the user has a login controller and register controller class included in the laravel application which automates the Bcrypt for authentication and registration. It is an adaptive choice to hash the passwords as the work factor is flexible.
use Illuminate\ Http \Request;
use Illuminate\Suppor t\Facades \Hash;
use App\ Http\ Controllers\ Controller;
class Update Password Controller extends Controller
* Update the password.
* Request $request
public function update (Request $request)
// Validate the length of the password...
$request -> user() -> fill ([
'password' => Hash :: make($request -> newPassword)
]) -> save ();
- To verify the password check method is implied and the need rehearse function is used to perform rehashing values.
Hence Laravel hash is used to provide the user a strong and secured method to protect the password and has a simple and easy configuration as explained.
