验证ONTAP 调解器代码签名

贡献者
PDF

在安装ONTAP调解器安装包之前、您应验证ONTAP调解器代码签名。

开始之前

在验证ONTAP调解器代码签名之前、您的系统必须满足以下要求。

  • OpenSSL 1.0.2到3.0版、用于基本验证

  • 适用于时间戳颁发机构(TSA)操作的OpenSSL 1.1.0或更高版本

  • 用于OCSP验证的公有 Internet访问

下载包中包含以下文件：

文件

Description

ONTAP-Mediator-production.pub

用于验证签名的公共密钥

csc-prod-chain-ONTAP-Mediator.pem

公共认证CA信任链

csc-prod-ONTAP-Mediator.pem

用于生成密钥的证书

ontap-mediator-1.9.0

1.9.0版的产品安装可执行文件

ontap-mediator-1.9.0.sig

SHA-256经过哈希处理、然后使用Ccs-prod密钥(安装程序签名)进行RSA签名

ontap-mediator-1.9.0.sig.tsr

OCSCP用于安装程序签名的撤消请求

ontap-mediator-1.9.0.tsr

时间戳签名请求文件

tsa-prod-ONTAP-Mediator.pem

TSR的公共证书

tsa-prod-chain-ONTAP-Mediator.pem

TSR的公共证书CA链
步骤

  1. 对执行撤消检查 csc-prod-ONTAP-Mediator.pem 使用联机证书状态协议(OCSP)。

    1. 查找用于注册证书的OCSP URL、因为开发人员证书可能不提供URI。

      openssl x509 -noout -ocsp_uri -in csc-prod-chain-ONTAP-Mediator.pem

    2. 生成证书的OCSP请求。

      openssl ocsp -issuer csc-prod-chain-ONTAP-Mediator.pem -CAfile csc-prod-chain-ONTAP-Mediator.pem -cert csc-prod-ONTAP-Mediator.pem  -reqout req.der

    3. 连接到OCSP Manager以发送OCSP请求：

      openssl ocsp -issuer csc-prod-chain-ONTAP-Mediator.pem -CAfile csc-prod-chain-ONTAP-Mediator.pem -cert csc-prod-ONTAP-Mediator.pem  -url ${ocsp_uri} -resp_text -respout resp.der -verify_other csc-prod-chain-ONTAP-Mediator.pem

  2. 验证CSC的信任链以及本地主机的到期日期：

    openssl verify

    备注 。 openssl 路径中的版本必须有效 cert.pem (非自签名)。 
    openssl verify -untrusted csc-prod-chain-ONTAP-Mediator.pem -CApath ${OPENSSLDIR} csc-prod-ONTAP-Mediator.pem  # Failure action: The Code-Signature-Check certificate has expired or is invalid. Download a newer version of the ONTAP Mediator.
openssl verify -untrusted tsa-prod-chain-ONTAP-Mediator.pem -CApath ${OPENSSLDIR} tsa-prod-ONTAP-Mediator.pem  # Failure action: The Time-Stamp certificate has expired or is invalid. Download a newer version of the ONTAP Mediator.

  3. 使用关联证书验证 `ontap-mediator-1.9.0.sig.tsr`和 `ontap-mediator-1.9.0.tsr`文件：

    openssl ts -verify

    备注 .tsr 文件包含与安装程序关联的时间戳响应以及代码签名。处理过程会确认时间戳具有来自TSA的有效签名、并且您的输入文件未更改。 此验证将在您的计算机上本地执行。独立地、无需访问TSA服务器。 
    openssl ts -verify -data ontap-mediator-1.9.0.sig -in ontap-mediator-1.9.0.sig.tsr -CAfile tsa-prod-chain-ONTAP-Mediator.pem -untrusted tsa-prod-ONTAP-Mediator.pem
openssl ts -verify -data ontap-mediator-1.9.0 -in ontap-mediator-1.9.0.tsr -CAfile tsa-prod-chain-ONTAP-Mediator.pem -untrusted tsa-prod-ONTAP-Mediator.pem

  4. 根据密钥验证签名：

    openssl -dgst -verify

    openssl dgst -sha256 -verify ONTAP-Mediator-production.pub -signature ontap-mediator-1.9.0.sig ontap-mediator-1.9.0
