Generate Laravel App Key Online
Once installed, the simple laravel new command will create a fresh Laravel installation in the directory you specify. For instance, laravel new blog would create a directory named blog containing a fresh Laravel installation with all dependencies installed. APPKEYS are set when you initialized a new Laravel application or executed the following command php artisan key:generate Laravel uses the key for all encrypted cookies, including the session cookie, before handing them off to the user’s browser, and it uses it to decrypt cookies read from the browser. I'm trying out the PHP micro Framework Lumen (from Laravel). One of my first steps was to look into the.env.example file and make a copy of it to have my.env file. There is a variable APPKEY just. In this post we will cover Laravel Fundamentals using 5.0. $ composer create-project laravel/laravel laravel-5-fundamentals '5.0.' -prefer-dist $ cd laravel-5-fundamentals $ php artisan serve This will launch a web server in your browser. You can view it on localhost:8000. Create a Controller Laravel follows the MVC pattern like other web. Jan 26, 2017 Now we will generate a random code of the form XXXX-XXXX-XXXX-XXXX-XXXX for the user such that X is a hexadecimal character and always in uppercase. We will use a feature provided by the Keygen package called Key Transformation to transform randomly generated bytes to our desired code. What is a Key Transformation?
Introduction
Laravel's encrypter uses OpenSSL to provide AES-256 and AES-128 encryption. You are strongly encouraged to use Laravel's built-in encryption facilities and not attempt to roll your own 'home grown' encryption algorithms. All of Laravel's encrypted values are signed using a message authentication code (MAC) so that their underlying value can not be modified once encrypted.
Configuration
Before using Laravel's encrypter, you must set a key option in your config/app.php configuration file. You should use the php artisan key:generate command to generate this key since this Artisan command will use PHP's secure random bytes generator to build your key. If this value is not properly set, all values encrypted by Laravel will be insecure.

Encrypting A Value
Laravel App Class
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 detect any modifications to the encrypted string:
{note} Encrypted values are passed through serialize during encryption, which allows for encryption of objects and arrays. Thus, non-PHP clients receiving encrypted values will need to unserialize the data.
Decrypting A Value
You may decrypt values using the decrypt helper. If the value can not be properly decrypted, such as when the MAC is invalid, an IlluminateContractsEncryptionDecryptException will be thrown:
Introduction
The Laravel Hashfacade provides secure Bcrypt and Argon2 hashing for storing user passwords. If you are using the built-in LoginController and RegisterController classes that are included with your Laravel application, they will use Bcrypt for registration and authentication by default.
{tip} Bcrypt is a great choice for hashing passwords because its 'work factor' is adjustable, which means that the time it takes to generate a hash can be increased as hardware power increases.
Configuration
The default hashing driver for your application is configured in the config/hashing.php configuration file. There are currently three supported drivers: Bcrypt and Argon2 (Argon2i and Argon2id variants).
{note} The Argon2i driver requires PHP 7.2.0 or greater and the Argon2id driver requires PHP 7.3.0 or greater.
I am designing a table and I have decided to create an auto-generated primary key value as opposed to creating my own scheme or using natural keys. I see that SQL Server offers globally unique identifiers (GUIDs) as well as identities to create these valu. How do I auto increment the primary key in a SQL Server database table, I've had a look through the forum but can't see how. I've looked the the properties but can't see an option, I have seen an answer where you go to the Identity specification property and set it to yes and set the Identity increment to 1, but that section is grayed out and I can't change the no to yes. 
The first is PRIMARY KEY, which as the name suggests, forces the specified column to behave as a completely unique index for the table, allowing for rapid searching and queries. While SQL Server only allows one PRIMARY KEY constraint assigned to a single table. Using auto generated keys.; 2 minutes to read +2; In this article. Because SQL Server doesn't support pseudo columns for identifiers, updates that have to use the auto-generated key feature must operate against a table that contains an IDENTITY column. SQL Server allows only a single IDENTITY column per table. AUTO INCREMENT Field. Auto-increment allows a unique number to be generated automatically when a new record is inserted into a table. Often this is the primary key field that we would like to be created automatically every time a new record is inserted.
Basic Usage
You may hash a password by calling the make method on the Hash facade:
Adjusting The Bcrypt Work Factor
If you are using the Bcrypt algorithm, the make method allows you to manage the work factor of the algorithm using the rounds option; however, the default is acceptable for most applications:
Adjusting The Argon2 Work Factor
If you are using the Argon2 algorithm, the make method allows you to manage the work factor of the algorithm using the memory, time, and threads options; however, the defaults are acceptable for most applications:
{tip} For more information on these options, check out the official PHP documentation.
Verifying A Password Against A Hash
The check method allows you to verify that a given plain-text string corresponds to a given hash. However, if you are using the LoginControllerincluded with Laravel, you will probably not need to use this directly, as this controller automatically calls this method:
Checking If A Password Needs To Be Rehashed
The needsRehash function allows you to determine if the work factor used by the hasher has changed since the password was hashed:
