验证的 PGP 签名 AWS OpsHub （可选）

Linux 操作系统的 AWS OpsHub 应用程序安装程序包采用加密签名。您可以使用公钥验证安装程序包是否为未修改的原始包。如果文件有任何损坏或更改，则验证将失败。您可以使用 GNU Privacy Guard（GPG）验证安装程序包的签名。此验证是可选的。如果您选择验证应用程序的签名，则可以随时进行验证。

你可以从AWS Snowcone 资源或 Snowball Edge 资源中下载 Linux 操作系统安装程序的 SIGNATURE 文件。

2. 将公钥导入到您的密钥环中，并记下返回的键值。

   GPG

   gpg --import opshub-public-key.pgp

   示例输出

   gpg: key 1655BBDE2B770256: public key "AWS OpsHub for Snow Family <[e-mail]>" imported
   gpg: Total number processed: 1
   gpg:               imported: 1

3. 验证指纹。请务必将 key-value 替换为上一步中的值。建议您使用 GPG 来验证指纹。

   gpg --fingerprint key-value

   该命令会返回类似以下内容的输出。

   pub   rsa4096 2020-12-21 [SC]
         372F A5E9 4869 8F77 D1B3  AFAA 2181 CF5A 74F3 45F1
   uid           [ unknown] AWS OpsHub for Snow Family <[e-mail]>
   sub   rsa4096 2020-12-21 [E]

   指纹应与以下内容匹配：

   372F A5E9 4869 8F77 D1B3 AFAA 2181 CF5A 74F3 45F1

   如果指纹不匹配，请不要安装 AWS OpsHub 应用程序。联系 AWS Support。

4. 根据您的实例架构和操作系统验证安装程序包并下载签名文件（如果您尚未执行此操作）。

5. 验证安装程序包签名。请务必将 signature-filename 和 OpsHub-download-filename 替换为您在下载签名文件和 AWS OpsHub 应用程序时指定的值。

   GPG

   gpg --verify signature-filename OpsHub-download-filename

   该命令会返回类似以下内容的输出。

   GPG

   gpg: Signature made Mon Dec 21 13:44:47 2020 PST
   gpg:                using RSA key 1655BBDE2B770256
   gpg: Good signature from "AWS OpsHub for Snow Family <[e-mail]>" [unknown]
   gpg: WARNING: This key is not certified with a trusted signature!
   gpg:          There is no indication that the signature belongs to the owner.
   Primary key fingerprint: 9C93 4C3B 61F8 C434 9F94  5CA0 1655 BBDE 2B77 0256

   在使用 GPG 时，如果输出包含短语 BAD signature，则检查是否正确执行了此过程。如果您继续收到此回复，请联系 AWS Support 并不要安装代理。有关信任的警告消息并不意味着签名无效，只是您尚未验证公有密钥而已。只有当您或您信任的某个人对密钥进行了签名，密钥才是可信的。
