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. To create a migration, use the make:migration Artisan command: php artisan make:migration createuserstable. The new migration will be placed in your database/migrations directory. Each migration file name contains a timestamp, which allows Laravel to determine the order of the migrations.
I’m trying out the PHP micro Framework Lumen (from Laravel).
Laravel Advent Calendar 2017 22日目の記事です。. Laravelerにおなじみ？、最初にやらされる php artisan key:generate 。 それで.env に APPKEY=base64:xxxxxxx が埋まりますよね。 自分はLaravel5くらいから使っているんですが、あれって具体的に何に使われているんだろうと思って、今回調べてみました！.
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 APP_KEY just like there is in Laravel. Now I tried out the simple command php artisan key:generate to get my new key But I ran into the following error message:
[InvalidArgumentException] There are no commands defined in the “key”
namespace.

Does some one know how I can generate keys for Lumen?
Update with solution
So I found my favorite solution for this problem. On the command line (Linux) I run php -r 'echo md5(uniqid()).'n';' what gives me something like this 7142720170cef01171fd4af26ef17c93.
If you are going to use Lumen more often, you may want to create an alias in your .bashrc, which is located in your home directory /home/USERNAME. To do so, you can open the file with nano ~/.bashrc or vi ~/.bashrc and copy the following alias at the end of the file, alias phpkey='php -r 'echo md5(uniqid()).'n';'. Now you can use the command phpkey which will give you a 32 character long random string 🙂
The Laravel command is fairly simple. It just generates a random 32 character long string. You can do the same in Lumen. Just temporarily add a route like this:
Then go to /key in your browser and copy paste the key into your .env file.
Afterwards remove the route.
Obviously you could also use some random string generator online. Like this one
Answer：
Firstly, you have to register your key generator command, put this Lumen Key Generator Commands to app/Console/Commands/KeyGenerateCommand.php. To make this command available in artisan, change appConsoleKernel.php:
After that, configure your application so that IlluminateConfigRepository instance has app.key value. To do this, change bootstrap/app.php:
After that, copy your .env.example file to .env:
Ignore this step if you already use .env file.
Enjoy you key:generate command via:
Edit
You may use Lumen Generator. It covers so much commands you are missing from Laravel.
Answer：
An easy solution is just running PHP code from the terminal (without using tinker, because that is not available with Lumen):
Php Base64 File
It uses Laravel’s Str::random() function that makes use of the secure random_bytes() function.
Answer：
For me the easiest way to generate a Lumen key is typing on console one of these commands:
or
openssl rand -base64 24
depending of your environment. In my case, I aways use date md5 on mac
Answer：
The APP_KEY generation is a step of development process (I don’t think that creating temporarily routes is a practical way to do it). The function str_random can help us, but this function is part of Laravel/Lunmen framework.
I recommend running tinker
php artisan tinker
and then run the function
>>> str_random(32)
The result is the key you’re looking for.

Answer：
Simply use PHP CLI. Run this from your local or a remote command line to generate a random 32-character Lumen APP_KEY:
Output: bae48aba23b3e4395b7f1b484dd25192
Works with PHP 7.x on Mac and Windows.
Answer：
To generate key and use laravel command you need to install one package. The details are as below:
- You have to install package
composer require flipbox/lumen-generator - You have to add
$app->register(FlipboxLumenGeneratorLumenGeneratorServiceProvider::class);intobootstrap/app.phpfile.
Link: https://github.com/flipboxstudio/lumen-generator
Answer：
I have used these commands:
The command generates a key similar to this:
$2y$10$jb3kw/vUANyzZ4ncMa4rwuR09qldQ2OjX8PGrVB5dIlSnUAPCGjFe
Answer：
All I do on mac is execute this command in the terminal:
This copies the value into the clipboard and so you can easily paste the key into the .env file.
Answer：
Run php -a to start up interactive php playground.
Then run echo substr(md5(rand()), 0, 32); to generate a 32 character string.
You can then copy/paste into the .env file.
Answer：
This answer was inspired by @thomas-venturini ‘s update to the question. Here’s a bash script that takes care of creating .env and updating it with an APP_KEY using the aforementioned PHP command and the UNIX sed command:
Hope someone finds this useful.
Answer：
1.Open your terminal setup file:
2.Create an alias for generating random strings:
Php Base64 Encode Image
3.Get a key whenever you need:
You can also remove the third step by adding the key directly in .env using PHP.
Php Base64 Decode
