CA Certificate Authentication Overview for MQTT Security - ApsaraMQ for MQTT - Alibaba Cloud - ApsaraMQ for MQTT

Queries all certificate authority (CA) certificates registered with a specified ApsaraMQ for MQTT instance. CA certificates are used to issue and validate device certificates for X.509 certificate-based client authentication.

Operation description

Only ApsaraMQ for MQTT Enterprise Platinum Edition instances support this operation.
You can call this operation up to 500 times per second per Alibaba Cloud account. If you want to increase the limit, join the DingTalk group (ID: 35228338) to contact ApsaraMQ for MQTT technical support.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
