What does signing mean?

A profile can be signed to prevent them from being tampered with after creation. Also, when installing the profiles on a device, it will be marked as "Verified" and install without warning about profile signatures.

How does this work?

This website uses OpenSSL on the server to sign the created profile using S/MIME. The certificates used are saved on the server and issued by Let's Encrypt. The exact backend code can be found on Codeberg.

What happens when the certificate expires?

Let's Encrypt certificates are valid 90 days from the day of issue. When attempting to install a profile with an expired certificate, iOS/macOS will treat it the same as an unsigned profile. A profile that is already installed when the certificate expires will stay installed, but change status from "Verified" to "Unverified".

What is the system scope?

The profile can be marked to use "system" as a scope. The exact effects of this depend on each single application.

Please see this GitHub issue for further information and discussion on the subject.
