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.\n\nNow I have another idea.\n\nWhat if I moved SkySigner onto a USB drive and turned it into a portable Nostr signing device?\n\nI 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.\n\nOf 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.\n\nBut could something like this work? Would a bootable USB environment be a better approach than simply running the application from a USB drive?\n\nHas anyone here experimented with something similar for Nostr?\n\nI am curious about both the technical possibilities and the security limitations.\n\n#asknostr #nostr #skysigner #nip07 #nip46 #bitcoin #cryptography #opensource #programming #linux #buildinpublic"}
