GitHubのSSH keysが消えた

GitHub で clone しようとしたら、

$ git clone git@github.com:＊＊＊/＊＊＊.git
Cloning into '＊＊＊'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

SSH公開キーを生成

$ ssh-keygen -t rsa
