I have another question about SkySigner.
For those who have not heard of it before. SkySigner is a Nostr signer I have been developing. The idea is to let Nostr clients and websites request signatures without giving them direct access to the private key. I have been experimenting with NIP-07 and NIP-46 and testing compatibility with different clients.
Now I have another idea.
What if I moved SkySigner onto a USB drive and turned it into a portable Nostr signing device?
I am wondering if it would be possible to plug the USB drive into a computer and use SkySigner to approve signing requests while keeping the private key isolated from the applications requesting signatures.
Of course a regular USB drive is not the same as a hardware wallet. I am aware that security would be one of the biggest challenges.
But could something like this work? Would a bootable USB environment be a better approach than simply running the application from a USB drive?
Has anyone here experimented with something similar for Nostr?
I am curious about both the technical possibilities and the security limitations.
