Create and issue an external subordinate CA certificate using a CSR and API parameters.

Operation description

Request

  • Creates an external subordinate CA certificate from a certificate signing request (CSR) and optional API pass-through parameters.

  • The required InstanceId parameter specifies the instance ID of the external subordinate CA.

  • The Csr parameter must contain a valid certificate signing request.

  • The Validity parameter specifies the certificate's validity period and accepts values in either relative or absolute time formats.

  • The ApiPassthrough parameter lets you override information in the CSR, such as subject information, or add certificate extensions.

  • Note: For end-entity CA certificates, set the pathLenConstraint parameter to 0.

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.

Request parameters

Parameter

Type

Required

Description

Example
InstanceId

string

No

The ID of the external subordinate CA instance.

cas_deposit-cn-1234abcd
Csr

string

No

The certificate signing request (CSR). The CSR can contain information such as the SubjectDN and custom extensions for the CA certificate. The CA generates the SubjectKeyIdentifier, AuthorityKeyIdentifier, and CRLDistributionPoints extensions, ignoring any corresponding values in the CSR.

-----BEGIN CERTIFICATE REQUEST----- MIIBczCCARgCAQAwgYoxFDASBgNVBAMMC2FsaXl1bi50ZXN0MQ0wCwYDVQQ ... vbIgMQIhAKHDWD6/WAMbtezAt4bysJ/BZIDz1jPWuUR5GV4TJ/mS -----END CERTIFICATE REQUEST-----

Validity

string

No

The certificate validity period. You can specify this using either relative or absolute time.

Note

Relative time: Supported units are year, month, and day.

  • y - year

  • m - month

  • d - day

Note

Absolute time: Use GMT time in the yyyy-MM-dd'T'HH:mm:ss'Z' format.

  • To specify only the expiration time, use $NotAfter.

  • To specify both the start and expiration times, use $NotBefore/$NotAfter.
