使用 PKCS7 签名验证 实例身份文档

本主题说明如何使用 PKCS7 签名和 Amazon DSA 公有证书验证实例身份文档。

使用 PKCS7 签名和 Amazon DSA 公有证书验证实例身份文档

  1. 连接到实例。

  2. 从实例元数据中检索 PKCS7 签名，并将其添加到名为 pkcs7 的文件。

    1. 将 -----BEGIN PKCS7----- 标头添加到 pkcs7 文件中。 

      $ echo "-----BEGIN PKCS7-----" > pkcs7

    2. 从实例元数据中检索 PKCS7 签名，并将其附加到 pkcs7 文件。根据实例使用的 IMDS 版本，使用以下命令之一。

      IMDSv2
      $ TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` \
&& curl -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/dynamic/instance-identity/pkcs7 >> pkcs7
      IMDSv1
      $ curl -s http://169.254.169.254/latest/dynamic/instance-identity/pkcs7 >> pkcs7

    3. 将 -----END PKCS7----- 脚注附加到 pkcs7 文件中的新行。 

      $ echo "" >> pkcs7
$ echo "-----END PKCS7-----" >> pkcs7

  3. 将实例元数据中 实例身份文档 的内容添加到名为 document 的文件。根据实例使用的 IMDS 版本，使用以下命令之一。

    IMDSv2
    $ TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` \
&& curl -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/dynamic/instance-identity/document > document
    IMDSv1
    $ curl -s http://169.254.169.254/latest/dynamic/instance-identity/document > document

  4. 将 Amazon DSA 公有证书添加到名为 certificate 的文件。

    1. 创建 certificate 文件。 

      $ touch certificate

    2. 使用首选文本编辑器打开 certificate 文件，然后添加 Amazon DSA 公有证书的内容。为您实例所在的 Amazon 区域选择正确的证书。

      重要

      如果下面未列出您所在区域的 Amazon DSA 公有证书，请联系 Amazon Web Services Support。

    3. 保存并关闭 文件。

  5. 使用 OpenSSL smime 命令来验证签名。包括 -verify 选项以指示需要验证签名，而包括 -noverify 选项则指示不需要验证证书。 

    $ openssl smime -verify -in pkcs7 -inform PEM -content document -certfile certificate -noverify

    如果签名有效，则会显示 Verification successful 消息。如果无法验证签名，请联系 Amazon Web Services Support。
