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.

3、列出密钥

C:\WINDOWS\system32>gpg --list-keys
#显示公钥文件名
C:/Users/user/AppData/Roaming/gnupg/pubring.gpg
-----------------------------------------------

#显示公钥特征
pub   2048R/0452FE75 2019-03-28
#显示用户ID
uid       [ultimate] ron.zheng (tfs) <ron.zheng@tfschange.com>
#显示私钥特征
sub   2048R/488F27D2 2019-03-28

4、将公钥导入到文件

公钥文件（.gnupg/pubring.gpg）以二进制形式储存，armor 参数可以将其转换为 ASCII 码显示。

gpg --armor --output "输出文件名" --export "用户ID"

gpg --armor --output C:/data/cert/test-public-key.asc --export  ron.zheng

在这里插入图片描述

打开查看公钥内容如下：

5、导出私钥

export-secret-keys 参数可以导出私钥。

gpg --armor --output C:/data/cert/tfs-private-key.asc --export-secret-keys

在这里插入图片描述

打开可看到私钥信息如下：

6、删除密钥，在命令行输入如下命令

必须先删除私钥，然后才能删除公钥。

在命令行输入如下命令：

gpg --delete-secret-keys 标识名
gpg --delete-keys 标识名
