# 1. 기존에 만든 키가 있는지 확인
```powershell
# 키 저장 위치로 이동
cd ~/.ssh

# 디렉터리 확인
dir

# result
# -a---        2024-04-26  오후 9:50           1876 id_rsa
# -a---        2024-04-26  오후 9:50            406 id_rsa.pub

# id_rsa.pub 파일이 존재하면 미리 생성해둔 키가 있는 것
# 키가 없다면 다음 1번부터 진행
```

# 2. 공개키-개인키 생성
    - 커맨드라인
    ```powershell
    ssh-keygen
    ```

    Generating public/private rsa key pair.
    Enter file in which to save the key (/home/path/.ssh/id_rsa):
    Created directory '/home/path/.ssh'.
    Enter passphrase (empty for no passphrase):
    Enter same passphrase again:
    Your identification has been saved in /home/path/.ssh/id_rsa
    Your public key has been saved in /home/path/.ssh/id_rsa.pub
    The key fingerprint is:

# 3. 생성한 공개키 Server로 전송하기
```powershell
type $env:[public key path] | ssh [username]@[remote-host] "cat >> .ssh/authorized_keys"
```

# 4. ssh 접속
```shell
ssh [username]@[remote-host]
```
