Now, Ed25519/X25519 is getting popular, **Gnuk Token** can be a practical choice for Debian Developers and Users.
In this short talk, we will explain the typical use case of **Gnuk Token** with **GnuPG**, and how **GnuPG** components (gpg front-end, gpg-agent, and scdaemon) interact.
We will explain:
- Use of gpg-agent as ssh-agent
- Storing private keys on physically independent device may reduce the attack surface
- Using Gnuk Token is convenient when we use multiple computers
This is an extension to the talk in Debconf17 (GnuPG 2.1 Explained for Everyone).
