OpenSSH

OpenSSH(from 8.2), the internet's most popular utility for managing remote servers, has added today support for the FIDO/U2F protocol.

与 FIDO 相关的SSH登陆算法一共4种:

  • sk-ecdsa-sha2-nistp256@openssh.com
  • sk-ecdsa-sha2-nistp256-cert-v01@openssh.com
  • sk-ssh-ed25519@openssh.com
  • sk-ssh-ed25519-cert-v01@openssh.com

FIDO U2F 使用 P-256 算法,而 FIDO2 使用 ED25519 算法。
