Problem description

When laravel5.1 is used for project development, an error message "No supported encrypter found. The cipher and/or key length are invalid." is displayed, causing The page to fail to be displayed.

Most answers on the Internet are directly executed.PHP artisan key:generateYou can. Some people find it feasible and some do not solve it.

Solution

The first step to solve this problem is to check the cipher value in config/app. php:

1. If the value of cipher is AES-256-CBC, it can be solved by generating a new key and then restarting nginx and php-fpm. The new key is directly written into the. env file.

2. But if cipher is another value, such as a rijndael-256, you need to install and start the mcrypt module. The reason the AES-256-CBC is not needed is that the underlying layer of the AES-256-CBC algorithm is implemented with openssl, not mcrypt. The rijndael-256 is dependent on the mcrypt module.

Check whether mcrypt is installed. The method can be executionphp -r “print_r(mcrypt_list_algorithms());”Whether there are output results, or viewphpinfo()Information.

If the mcrypt module has been installed, start the mcrypt module.

The method is to execute:php5enmod mcrypt

Restart nginx and php-fpm.
