No key available {"exception":"[object] (RuntimeException(code: 0): No key available at encryption

[jchan1993h4a40]

Hi all, I am installing Magento 2.4 using valet plus. In my exception log, I am having the error;

main.CRITICAL: No key available {"exception":"[object] (RuntimeException(code: 0): No key available at /XXXX/project-community-edition/vendor/magento/framework/Encryption/Encryptor.php:255)"} []

I assume this is because it is missing the access keys (public & private) within the Encryptor.php file? If so, where do I input this to get it working?

Hello @jchan1993h4a40 

Try by command line to install Magento 2.4 by following below article:

https://devdocs.magento.com/guides/v2.4/install-gde/composer.html

I am not sure that Magento 2.4 installation supports valet+ or not as Magento has removed UI installation/ setup wizard. You can give a composer try. 

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition <install-directory-name>

When prompted, enter your Magento authentication keys. Public and private keys are created and configured in your Magento Marketplace.

Hi @jchan1993h4a40 

It can be issue with your PHP version which is linked to php-libsodium, check some solutions provided here :

Hi @Manish Mittal, I have already ran that command and installed it. It is just giving me the errors when I try to load up the file.test. 

@gaurav_harsh1, thanks! I have given that a try but still no luck!

Thank you both

Have you tried all solutions shared ?

You must try with PHP 7.3 (if it's lower version)

Check this as well :

Check if your en.php has key value in it.
