The login to the admin does not work after a new installation of shopware 6.5. After entering correct username and passwor, the following error appears in the console: Key provided is shorter than 2048 bits, only 1024 bits provided
Tested on a standard environment at Mittwald: PHP 8.5 and MySQL 8.0.25-15 - installation via Composer.
Password has already been changed and a new user created - both via console. Still the same error.
The issue is that the openssl config default config on that system is configured to use a default key_length of 1024 bits.
As a workaround you can change that system wide default value to 2048 bits and run the bin/console system:generate-jwt-secret --force command.
We will fix the generation to always generate a key with a valid length independent of the system wide openssl configuration for the final 6.5 version.
