I am looking for a local encryption package that will work on a Chromebook.
The aim is to have a file stored on the Chromebook or an attached SD/USB device. Viewing the file will require entry of a password.
The package should operate with the Chromebook offline. Every possible solution I have seen so far requires an internet connection and operates on files that are stored in the cloud.
Freeware would be nice but I'm quite willing to pay for it.
