Hi,
I am making a Single Sheet SecurePrint backups for my Armory cold wallets.
One on TerraSlate paper using a public printing store, as I don't have a laser printer.
Another backup method I have is a PDF I store on a private s3 bucket, for the redundant storage.
The Root Key is kept completely separately.
If somehow this printed copy or bucket gets compromised is it feasible to brute force to get the Root Key?
Thanks for your help
