TrustKernel PlugMate : Secure Miniature USB-C Computer running PlugOS · File : plugmate-secure-clipboard.ino · Language : Kotlin · Use case : Copier des données sensibles dans le presse-papiers sans les exposer à l'hôte.

Manages the clipboard in an isolated manner, ensuring that data copied within PlugMate does not leak to the host operating system.

The Android clipboard on PlugMate is confined to the secure execution environment. This code uses the ClipboardManager API. Unlike a standard smartphone, pasting from the host is often blocked or controlled by the host client. For ultra-sensitive data, avoid the clipboard and use direct input fields.
