I’m trying out the PHP micro Framework Lumen (from Laravel).

Mar 11, 2020  How To Install Laravel 5 on Ubuntu 19.04, 18.04 and 16.04 LTS. Now generate base64 random number encryption key, which used by the Illuminate encrypter service. Php artisan key:generate Application key set successfully. Edit the.env configuration file and update the required settings. Also, make sure APPKEY is properly set as generated in. Sep 17, 2018  To create a new key, you could generate one yourself and paste it into your.env, or you can run php artisan key:generate to have Laravel create and insert one automatically for you. Once your app is running, there's one place it uses the APPKEY: cookies. 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.

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:

Php Base64 Encode Image

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):

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)

Base64 Decode With Key

The result is the key you’re looking for. https://cleverlinx920.weebly.com/blog/minecraft-mansion-map-download-mac.

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:

1. You have to install package composer require flipbox/lumen-generator
2. You have to add $app->register(FlipboxLumenGeneratorLumenGeneratorServiceProvider::class); into bootstrap/app.php file.

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.

Php Url Safe Base64

You can then copy/paste into the .env file.

Answer：

Php Base64 Decode

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. Key generation algorithm digital signature.

Answer：

Php Save Base64 Image

1.Open your terminal setup file:

Php Base64 Encode File

2.Create an alias for generating random strings:

3.Get a key whenever you need:

Php Artisan Key:generate Base64

You can also remove the third step by adding the key directly in .env using PHP.
