 gpg (GnuPG) 2.0.30; Copyright (C) 2015 Free Software Foundation, Inc.
 This is free software: you are free to change and redistribute it.
 There is NO WARRANTY, to the extent permitted by law.
 
 Please select what kind of key you want:
 (1) RSA and RSA (default)
 (2) DSA and Elgamal
 (3) DSA (sign only)
 (4) RSA (sign only)
 Your selection? 1 #选择密钥类型（这里我们选择加密算法是RSA、数字签名算法也是RSA）
 RSA keys may be between 1024 and 4096 bits long.
 What keysize do you want? (2048) 2048 #设置密钥的比特数
 Requested keysize is 2048 bits
 Please specify how long the key should be valid.
 0 = key does not expire
 <n> = key expires in n days
 <n>w = key expires in n weeks
 <n>m = key expires in n months
 <n>y = key expires in n years
 Key is valid for? (0) 0 #设置密钥有效期（永不过期）
 Key does not expire at all
 Is this correct? (y/N) y #确认有效性
 
 GnuPG needs to construct a user ID to identify your key.

 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][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3p5aGx3enk_size_16_color_FFFFFF_t_70]

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][20190328163212524.png]

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
