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


You only type in console:

php artisan key:generate

And if your app.php not change this Key, change manually.


Next if you should then happen to get this error message:

[ErrorException]
file_get_contents(/path/to/my/project/.env): failed to open stream: No such file or directory

Then make a copy of the .env.example file and try again:

cp .env.example .envphp artisan key:generate


Do you have all the necessary extensions installed on the server?

  • PHP >= 5.5.9
  • OpenSSL PHP Extension
  • PDO PHP Extension
  • Mbstring PHP Extension
  • Tokenizer PHP Extension

It could be that you're missing the OpenSSL extension. Also, do you have the key set in .env file?


Try running:

php artisan key:generate


Answer: the 'cipher' => '' was not set.


I have same issue before and I fixed it follow this way:Go to config/app.php, change "cipher" => "anything" to

'cipher' => MCRYPT_RIJNDAEL_128,
