gpg —list-keys 命令在将私钥导入全新安装后输出 uid [ unknown ]

Question

我全新安装了 Arch Linux 并导入了我备份的 gpg 私钥。作为健全性检查，我跑了：

gpg —list-keys

除了uid现在显示的内容外，一切都显示正常：

uid [ unknown ] User < user@useremail.com >

当我在全新安装之前首次创建此密钥时，它显示为：

uid [ ultimate ] User < user@useremail.com >

为什么在将其导入全新安装后会从[ ultimate ]变为[ unknown ]？

提前致谢。

Answer 1

GNUPG 有一个信任数据库存储在 ~/.gnupg/trustdb.gpg

您可以使用以下--export-ownertrust选项备份此信任数据库：

gpg --export-ownertrust > file.txt

如果您导出密钥并稍后将它们导入新环境，则信任数据库将不再存在。

但是，这很容易补救：

gpg --edit-key user@useremail.com

gpg> trust

Please decide how far you trust this user to correctly verify other users' keys
(by looking at passports, checking fingerprints from different sources, etc.)

  1 = I don't know or won't say
  2 = I do NOT trust
  3 = I trust marginally
  4 = I trust fully
  5 = I trust ultimately
  m = back to the main menu

Your decision? 5

并且不要忘记保存更改：

gpg> save
