Certificates for HTTPS and application signature and SSH keys are managed in Security > Keys and certificates.
Allow signed apps only
When the switch Allow signed applications only in on, only apps digitally signed by the manufacturer are allowed to install. This ensures that the code has not been tampered with and is a security feature. In normal mode, it is recommended that the switch is on.
Select the button Add key to add the application signature key (in PEM format).
SSH
