Offline device to generate wallets, keys and passwords. Incl. Air-gapped signing

[BitcoinDoe]

An offline device to minimize trust and generate Bitcoin wallets, encryption keys and passwords etc https://github.com/Offlinedevice/Offlinedevice.  All parts can be printed using a 3D-printer https://www.printables.com/model/1783754-raspberry-pi-with-rfid-camera-and-docking-station.

Air-gapped signing for files, messages and transactions. Offline signing of others public PGP keys.

Entropy can be generated by rolling of the dice.

Built using standard components found on the Internet and all software are open source.

Alt. use of NFC- hardware keys to login/decrypt device. Hardware can include a random salt to prevents brute force attack (if the attacker get hold of the encrypted backup or device and the device own encryption key.

Thanks for sharing. It looks like an excellent project if you're interested in how offline signing and cryptographic key management work.

As for storing a significant amount of Bitcoin, I'd still lean towards hardware wallets with a long security track record or wallets like electrum.
