Mac環境で公開鍵、秘密鍵を作成する方法の備忘録

別にMacに限らずLinux環境であればできる手順ですが...

鍵の作成

$ cd ~/.ssh
$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xxxxxx/.ssh/id_rsa): #作成先確認
Enter passphrase (empty for no passphrase): #パスフレーズ入力
Enter same passphrase again:
Your identification has been saved in /Users/xxxxxx/.ssh/id_rsa.
Your public key has been saved in /Users/xxxxxx/.ssh/id_rsa.pub.
The key fingerprint is:

:
略
:

$ ls -l
total 16
-rw-------  1 xxxxxx  staff  1876 12 25 21:16 id_rsa
-rw-r--r--  1 xxxxxx  staff   403 12 25 21:16 id_rsa.pub

鍵を使った接続

ssh -l <USER> -i <作った秘密鍵> <IPアドレス>
