§公開鍵認証を可能にする

クライアントマシン側で生成した公開鍵を ~/.ssh/authorized_keys に設置すれば公開鍵認証が可能になる。

クライアント側では次のようなコマンドで秘密鍵と公開鍵を生成できる。

ssh-keygen -t ed25519 -C 'yourmail@example.jp'

RSA 2048 bit 鍵でもよいが、Ed25519 鍵が使える環境であれば Ed25519 鍵を使いたい。

クライアント側では ~/.ssh/id_rsa~/.ssh/id_ed25519 などがあれば自動的にそれが使われるが、明示的に使いたい場合は ssh -i /path/to/id_ed25519 のようにオプションを付与して秘密鍵のパスを指定するか、次のように ~/.ssh/config ファイルを記述すればよい。

Host example.org
    HostName        203.0.113.123
    User            yourname
    IdentityFile    ~/.ssh/id_ed25519
