Protect PDF

Standard PDF encryption is applied by the processing service so the password handling never happens in shared client code.

This tool needs a server-side processing engine. The full interface and API adapter are in place — once an administrator configures the processing service, jobs run here without any further changes.

Encrypted upload, temporary storage, automatic deletion.
