Where can I get the encryption keys for the KDE wallet service?

Question

Debian

Hello. Installed Debian 9 with KDE. Internet connection via Wi-Fi. Each time you reboot, you will be prompted for a password to connect to the wireless access point. The KDE wallet service window also appears, suggesting either using the classic blowfish cipher, or using GPG encryption for the best security. I choose the second option, to which the service says: "It looks like there are no keys suitable for encryption on your system. Install at least one encryption key, and then try again." Actually the question is how to set "at least one encryption key"?
