ParagonIE\CipherSweet\KeyProvider\StringProvider::__construct(): Argument #1 ($rawKey) must be of type string, null given

[Astelll]

Hello!

I'm trying to encrypt data in my database by command:
php artisan ciphersweet:encrypt <your-model-class> <generated-key>
php artisan ciphersweet:encrypt "App\Models\User" da61321c8814fe47f6f647f26330bc34f88fd8c32c1df25af4f0b3a30dff00e9

but I receive such error
ParagonIE\CipherSweet\KeyProvider\StringProvider::__construct(): Argument #1 ($rawKey) must be of type string, null given, called in /var/www/fastuser/data/www/api.dev.clanhall.net/vendor/spatie/laravel-ciphersweet/src/LaravelCipherSweetServiceProvider.php on line 52

What am I doing wrong and how can I try to fix it?
All instructions from readme were executed

I asked this question at https://github.com/paragonie/ciphersweet/ project in this thread, and got such answer:

Adding on to this - it seems you need to set the key in .env first, even though the docs say not to. It's looking for the value of the env key, and it's null until you set it. The instructions likely need to be updated.

Bumped into this as well. Cannot run php artisan ciphersweet:generate-key until this is done, which is rather counter-intuitive. (And, it isn't obvious, but they key needs to be 32-characters long.)

@riasvdv could you have a look and update the readme if necessary?

[yormy]

I can confirm, just generating the key first (it does work), then copying that key to the env and then encrypt the model with the key like the docs mention works like a charm

I can also confirm that putting the key into the .env first before encrypting is required.

Additionally, if you're updating the readme, it might be useful for people to know that they may need to first create and run a migration on their encrypted model table fields to increase the size to accommodate the encryption value, since its likely larger than the original value.
