SSH (2) RSA認証

$ ssh-keygen -t rsa1 //鍵の作成
Generating public/private rsa1 key pair.
Enter file in which to save the key (/home/hogehoge/.ssh/identity): //ディフォルトで良いでしょう
Created directory '/home/hogehoge/.ssh'.
Enter passphrase (empty for no passphrase): //パスフレーズの入力
Enter same passphrase again: //パスフレーズの確認
Your identification has been saved in /home/hogehoge/.ssh/identity.
Your public key has been saved in /home/hogehoge/.ssh/identity.pub.

$ cd ~/.ssh

$ cp identity.pub authorized_keys

クライアントにはidentityファイルをコピーする。(秘密鍵)
よってクラインとはidentity(秘密鍵)を使って暗号化し
サーバーはautorized_key(公開鍵のコピー)を使って
認証及び復号を行う。 たぶん、、、
