Laravel supported ciphers are AES-128-CBC and AES-256-CBC
On a Laravel application, I get the following error message
The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths.
![Laravel error](https://serverok.in/wp-content/uploads/2022/05/laravel-ciphers-key-length.webp)
To fix the error, run the command
php artisan key:generate
This will generate a new key and add to the .env file.
Back to Laravel
