使用 base64 编码的签名验证 实例身份文档

本主题说明如何使用 base64 编码的签名和 Amazon RSA 公有证书验证实例身份文档。

使用 base64 编码的签名和 Amazon RSA 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 base64 编码的签名，将其转换为二进制文件，然后将其添加到名为 signature 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/signature | base64 -d >> signature
    IMDSv1
    $ curl -s http://169.254.169.254/latest/dynamic/instance-identity/signature | base64 -d >> signature

  3. 从实例元数据中检索明文 实例身份文档，并将其添加到名为 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 RSA 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。

  5. 从 Amazon RSA 公有证书中提取公有密钥，并将其保存到名为 key 的文件。

    $ openssl x509 -pubkey -noout -in certificate >> key

  6. 使用 OpenSSL dgst 命令来验证实例身份文档。

    $ openssl dgst -sha256 -verify key -signature signature document

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