Problem description

When using laravel5.1 for project development, there was "No supported Encrypter found. The cipher and/or key length is invalid. " Error message, causing the page to fail to display.

Most of the answers on the web are directly executed PHP artisan key:generate . Some people find it feasible and some are not solved.

Workaround

The first step in solving this problem is to look at the cipher value in config/app.php:

1. If the value of cipher is AES-256-CBC, then it can be resolved by generating a new key and then restarting Nginx and PHP-FPM. The generated new key is then written directly to the. env file.

2. However, if cipher is a different value, such as rijndael-256, you will need to install and start the MCrypt module. The reason why AES-256-CBC is not needed is that the AES-256-CBC algorithm corresponds to the underlying level that is implemented with OpenSSL and is not related to MCrypt. The rijndael-256 is dependent on the MCrypt module.

Check if MCrypt is installed. The method can be performed php -r “print_r(mcrypt_list_algorithms());” with or without output results, and there is a view of the phpinfo() information.

Start the MCrypt module if it is already installed.

The method is to execute:php5enmod mcrypt

Finally, the Nginx and PHP-FPM can be restarted.
