I’m considering developing a plugin on security recently. Since the data is stored locally in .md format and may contain a lot of sensitive data, it made me curious about a security question: how secure do you think is the local plaintext storage?
If we are more specific: how secure is local plaintext on Mac and iPhone?
If the device gets lost. I have opened FileVault on Mac and iPhone has a fingerprint lock and password. Is this secure enough?
Do some software scan the local files? How big is this risk?
Something like Spotlight on Mac does scan all the local plaintext, does this pose a security risk?
Are there any other risks you could think of?
The thing is: Local plaintext storage sounds beautiful, but is it really more secure than end-to-end encrypted cloud storage?
