验证 CA 认证中的 X509v3 扩展

使用以下命令验证 CA 认证中的 X509v3 扩展。

ONTAP Mediator 1.9 及更高版本

在 openssl_ca.cnf`中的 `v3_ca`内定义的属性将在 `intermediate.crt`中显示为 `X509v3 extensions。

                Digital Signature, Certificate Sign, CRL Sign

验证服务器证书和主题替代名称中的 X509v3 扩展

`openssl_server.cnf` 配置文件中定义的 `v3_req` 属性在证书中显示为 `X509v3 extensions`。

在以下示例中，您可以通过在安装了 ONTAP Mediator 的 Linux VM 上运行命令 `hostname -A`和 `hostname -I`来获取 `alt_names`部分中的变量。

请与网络管理员联系以获取变量的正确值。

验证私钥是否与证书匹配

您可以验证特定私钥是否与证书匹配。

分别在密钥和证书上使用以下 OpenSSL 命令。

ONTAP Mediator 1.9 及更高版本
[root@mediator_host server_config]# openssl rsa -noout -modulus -in intermediate.key | openssl md5
Enter pass phrase for intermediate.key:
(stdin)= 14c6b98b0c7c59012b1de89eee4a9dbc
[root@mediator_host server_config]# openssl x509 -noout -modulus -in intermediate.crt | openssl md5
(stdin)= 14c6b98b0c7c59012b1de89eee4a9dbc
ONTAP Mediator 1.8 及更早版本
[root@mediator_host server_config]# openssl rsa -noout -modulus -in ca.key | openssl md5
Enter pass phrase for ca.key:
(stdin)= 14c6b98b0c7c59012b1de89eee4a9dbc
[root@mediator_host server_config]# openssl x509 -noout -modulus -in ca.crt | openssl md5
(stdin)= 14c6b98b0c7c59012b1de89eee4a9dbc

如果两者的 `-modulus`属性匹配，则表明私钥和证书对是兼容的，并且可以协同工作。

确认从特定 CA 证书创建了服务器证书

您可以使用以下命令验证服务器证书是否是从特定 CA 证书创建的。

ONTAP Mediator 1.9 及更高版本
[root@mediator_host server_config]# openssl verify -CAfile root_ca.crt --untrusted intermediate.crt ontap_mediator_server.crt
ontap_mediator_server.crt: OK
[root@mediator_host server_config]#
ONTAP Mediator 1.8 及更早版本
[root@mediator_host server_config]# openssl verify -CAfile ca.crt ontap_mediator_server.crt
ontap_mediator_server.crt: OK

如果正在使用在线证书状态协议（OCSP）验证，请使用命令 "openssl-verify"。
