1. 创建一个新的gpg: 

# Ubuntu
sudo apt-get install gpa seahorse
# MacOS with https://brew.sh/
brew install gpg

2. 生成: gpg --gen-key

3. 列出来:

gpg --list-secret-keys --keyid-format=long

4. 复制上面的 E056D7D3A36CE2FA  ，然后列出它的完整内容：

$ gpg --armor --export E056D7D3A36CE2FA

结果如下图；

5. 把上图红框的内容，粘贴到github中去。具体路径为：settings -> ssh and gpg keys -> new gpg key
