# Git and GitHub config
###### tags: `邁向全端修煉之路`, `Git` `GitHub`

## Config
`$ git config --global user.name <user-name>`
`$ git config --global user.email <user-email>`

## Public and Private Keys
1. GitHub 從2021年開始不建議使用密碼驗證(HTTP)，建議用SSH連線方式操作Git repo
2. 公私鑰觀念
3. Create SSH Keys
* `$ ssh-keygen -t ed25519 -C "your email"`: generate public and private key to `~/.ssh` folder.
4. Add SSH Key to ssh-agent:
* Make sure ssh-agent is running in the background.

        $ eval `ssh-agent`

(這邊有些人的寫法是`eval "$(ssh-agent) -s"`，但會報錯)

* Add your SSH private key to the ssh-agent.

        $ ssh-add ~/.ssh/ed_25519

5. Add SSH Key to GitHub Account
* `$ cat ~/.ssh/ed_25519.pub` and copy the output and paste into GitHub.

6. Test SSH connection with a Repo
