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

4. Php Artisan Key Generate Renew Passport

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.

Aug 24, 2017  Running php artisan key:generate in a Laravel project where the.env file does not contain an APPKEY= line results in the following output: Application key base64:KEYHERE= set successfully. However, the key is not written to the.env file, so the status message is incorrect. Steps To Reproduce: Create a.env file without an APPKEY= line.

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

Free Key Generate Software

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.

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.

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.

For me the easiest way to generate a Lumen key is typing on console one of these commands:

or Windows xp sp3 generator key.

openssl rand -base64 24

depending of your environment. In my case, I aways use date md5 on mac

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.

The key:generate command is used to generate a random key. This command will update the key stored in the application's environment file. The command also supports an optional --show flag. Specifying this flag will simply show the generated key instead of updating any configuration or environment files.

The following example demonstrates how to update/change the application's key:

Regenerating the Application Key

It is important to note that if the encryption key needs to be regenerated after an application has been in use, any data that was previously encrypted using the old key cannot be decrypted using the new encryption key. While regenerating the encryption key is not recommended, there are some scenarios where it is beneficial, if not absolutely critical to do so.

When these scenarios arise, the problems can be overcome by decrypting the old data and reapplying the encryption using the new encryption key.

The following example will simply display the generated key instead of displaying it:

The output will be similar to the following, but the key will most likely be different:
