如何使用 gpg 更新过期的加密子密钥

  • 772

我更新了我的 gpg 密钥对，但我仍然收到来自 gpg 的以下错误。

gpg: WARNING: Your encryption subkey expires soon.
gpg: You may want to change its expiration date too.

如何更新子密钥？

    列出你的钥匙。

    
$ gpg --list-keys
...
-------------------------------
pub   rsa2048 2019-09-07 [SC] [expires: 2020-11-15]
      AF4RGH94ADC84
uid           [ultimate] Jill Doe (CX) <[email protected]>
sub   rsa2048 2019-09-07 [E] [expired: 2019-09-09]

pub   rsa2048 2019-12-13 [SC] [expires: 2020-11-15]

    我们要编辑密钥 AF4RGH94ADC84。子项是列表中第二个被命名的子项ssb

    
$ gpg --edit-key AF4RGH94ADC84

gpg> list

sec  rsa2048/AF4RGH94ADC84
     created: 2019-09-07  expires: 2020-11-15  usage: SC
     trust: ultimate      validity: ultimate
ssb  rsa2048/56ABDJFDKFN
     created: 2019-09-07  expired: 2019-09-09  usage: E
[ultimate] (1). Jill Doe (CX) <[email protected]>

    所以我们要编辑第一个子键（ssb）

    ssb  rsa2048/56ABDJFDKFN
     created: 2019-09-07  expired: 2019-09-09  usage: E
[ultimate] (1). Jill Doe (CX) <[email protected]>

    当您选择键 (1) 时，您应该会看到它旁边的 *，例如ssb*。然后你可以设置过期时间然后保存。

    gpg> key 1

sec  rsa2048/AF4RGH94ADC84
     created: 2019-09-07  expires: 2020-11-15  usage: SC
     trust: ultimate      validity: ultimate
ssb*  rsa2048/56ABDJFDKFN
     created: 2019-09-07  expired: 2019-09-09  usage: E

gpg> expire
...

Changing expiration time for a subkey.
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) 2y
Key expires at Wed 9 Sep 16:20:33 2021 GMT
Is this correct? (y/N) y

sec  rsa2048/AF4RGH94ADC84
     created: 2019-09-07  expires: 2020-11-15  usage: SC
     trust: ultimate      validity: ultimate
ssb*  rsa2048/56ABDJFDKFN
     created: 2019-09-07  expires: 2021-09-09  usage: E

gpg> save

    退出前不要忘记保存更改！

  2. 我通过安装和使用 openPGP 解决了这个问题。点击“过期”按钮；它不会接受“永不过期”，但您可以设置未来的日期。
