I am using laravel 5.2 and I have been authenticating myself, but when I run the command php artisan make:auth it works perfect, but in practice it does not ... When I click login or register it gives me this error:

No supported encrypter found. The cipher and / or key length are invalid.

How can I fix it? Composer.json:

First of all, you must generate your APP_KEY:

php artisan key:generate

If it still is not working, check the config / app.php file if it is set to:

'cipher' => 'AES-256-CBC'

And if the .env file exists ... if not, you should rename the .env.example to .env p>

If you navigated to the project folder and there is no .env.example , there was a failure in Laravel installation, when we installed Laravel the first time through the composer it generates a copy inside the composer folder, so if you create new ones projects (probably by artesian ) it will fetch from the local copy, check the folder that was installed, usually the location that is saved is ~/.composer/vendor/bin , if you think something failed to install the composer, use the command like this:

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

When creating a project use the --prefer-dist parameter, like this:

composer create-project --prefer-dist laravel/laravel meuprimeiroprojeto

To check if everything is ok, navigate to the folder by typing:

cd meuprimeiroprojeto
ls -a

Will display all files, should appear .env.example
