GPG是加密和数字签名的免费工具，大多用于加密信息的传递。

在Ubuntu下，用GPG命令可以实现文件的加密和解密，而且GPG基本上每个发行版都会预装。

gpg -c file # 加密一个文件,会生成file.gpg
    gpg file.gpg # 解密file.gpg 还原成file文件

常用基本命令

gpg --gen-key # 生成秘钥对
    gpg --list-keys # 查看已有的秘钥
    gpg --delete-secret-keys <...@qq.com> # 删除私钥
    gpg --delete-key <...@qq.com> # 删除公钥
    gpg --armor --output public.key --export <uid> # 导出私钥
    gpg --armor --output private.key --export-secret-keys <uid> # 导出公钥
    gpg --keyserver hkp://keyserver.ubuntu.com:11371 --send-keys <PUBLIC_KEY_ID> # 将公钥上传服务器

生成秘钥时候如果出现下面的提示后卡住

We need to generate a lot of random bytes. It is a good idea to perform
    some other action (type on the keyboard, move the mouse, utilize the
    disks) during the prime generation; this gives the random number
    generator a better chance to gain enough entropy.

手动安装一下面的软件即可解决问题！

sudo apt install rng-tools

下面是我在本地生成秘钥对并将公钥发到了服务器

公钥服务器：[http://keys.gnupg.net/][http_keys.gnupg.net]、[http://keyserver.ubuntu.com:11371/][http_keyserver.ubuntu.com_11371]
