问题解答

使用开放式SSL FIPS创建证书时、请务必选择支持的大小2048或3072。

根据 [1] ONTAP 9.x中命令security certificATE create的手册页:

-size <size of requested certificate in bits>-所请求证书的大小(以位为单位
)指定私钥中的位数。值越大、密钥越安全。默认值为2048。如果
"security config"中的"FIPS Mode"为false、则可能的值包括512、1024、1536、2048和3072。当"FIPS Mode"为true时,
可能的值为 2048和3072。

如果使用 'security certificate create' 命令、ONTAP将向您发出警告

示例:
cluster:*> security config show
         集群                                             安全
接口FIPS模式 支持的协议支持的加密器    配置就绪
------- -------- ----------------------- ----------------------- -----------------------
ssl       true      TLSv1.2            all:!low:!aNULL:!EXP:yes
                                        !eNULL:!3des
cluster::*> security certificATE create -common-name test -size 4096 错误:"4096"无效
字段"-size的值" 此命令上下文中的有效选项:2048、3072
 
 
示例:如果在密钥大小为4096的KMIP服务器上创建了证书 、然后将其安装在ONTAP中、则会执行以下操作
在尝试与KMIP服务器通信时出现:

cluster:>>security key-manager show -status
Node                   Port   已注册密钥管理       器状态
-----------------------  --------  -----------------------  --------
cluster-node1            5696   10.0.13.91                  unknown
cluster-node1            5696   10.0.13.92                  unknown
cluster-node1            5696   10.4.13.95                  unknown
cluster-node1            5696   10.4.13.96                  unknown
cluster-node2            5696   10.0.13.91                  unknown
cluster-node2            5696   10.0.13.92                  unknown
cluster-node2            5696   10.4.13.95                  unknown
cluster-node2            5696                     10.13.96未知
