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，并将其连同所需的页眉和页脚添加到名为 pkcs7 的新文件。根据实例使用的 IMDS 版本，使用以下命令之一。

    IMDSv2
    $ echo "-----BEGIN PKCS7-----" >> pkcs7 \
&& 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 \
&& echo "" >> pkcs7 \
&& echo "-----END PKCS7-----" >> pkcs7
    IMDSv1
    $ echo "-----BEGIN PKCS7-----" >> pkcs7 \
&& curl -s http://169.254.169.254/latest/dynamic/instance-identity/pkcs7 >> pkcs7 \
&& 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 的新文件。根据您的实例所在的地区，使用以下命令之一。

    Other Amazon Regions

    以下 Amazon 公有证书适用于除中国香港、巴林、开普敦、米兰、雅加达、中国和 GovCloud 之外的所有 Amazon 区域。
