    Certificate Management Service:CreateServerCertificateWithCsr

    Last Updated:Dec 24, 2025

    Issues a server-side certificate based on a custom Certificate Signing Request (CSR).

    Operation description

    Before you call this operation, you must call CreateRootCACertificate to create a root CA certificate and CreateSubCACertificate to create a subordinate CA certificate. Server-side certificates can be issued only by subordinate CA certificates.

    Limits

    This operation has a queries per second (QPS) limit of 10 requests per user. If you exceed this limit, rate limiting is triggered, which may affect your business. Call this operation only as needed.

    Try it now

    Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

    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.

    Type

    Required

    Description

    Example
    Csr

    string

    Yes

    You can generate a CSR using OpenSSL or Keytool. For more information, see How to create a CSR file.

    -----BEGIN CERTIFICATE REQUEST----- ...... -----END CERTIFICATE REQUEST-----
    Domain

    string

    No

    Additional domain names or IP addresses for the server-side certificate. Adding this information lets you apply the certificate to multiple domains or IP addresses.

    You can enter multiple domain names and IP addresses. Separate them with commas (,).

    example.com
    Organization

    string

    No

    Organization name. Default: Alibaba Inc.

    阿里云
    OrganizationUnit

    string

    No

    Department name. Default: Aliyun CDN.

    IT
    Country

    string

    No

    Country code, such as CN.

    CN
    CommonName

    string

    No

    Set the common name for the certificate. Supports Chinese, English, and other characters.

    Note

    If you set the Csr parameter, the value of CommonName comes from the corresponding field in the Csr parameter.

    mtcsq.com
    State

    string

    No

    Set the name of the state or province where the organization is located. Supports Chinese, English, and other characters. Defaults to the state or province of the issuing sub-CA certificate's organization.

    Zhejiang
    Locality

    string

    No

    The city where the organization for the certificate is located. The name can contain both Chinese and English characters. By default, this parameter is set to the city of the organization for the issuing subordinate Certificate Authority (CA).

    Hangzhou
    Algorithm

    string

    No

    Key algorithm for the server-side certificate. Use the format <encryption algorithm>_<key length>. Valid values:

    • RSA_1024: Signature algorithm is Sha256WithRSA.

    • RSA_2048: Signature algorithm is Sha256WithRSA.

    • RSA_4096: Signature algorithm is Sha256WithRSA.

    • ECC_256: Signature algorithm is Sha256WithECDSA.

    • ECC_384: Signature algorithm is Sha256WithECDSA.

    • ECC_512: Signature algorithm is Sha256WithECDSA.

    • SM2_256: Signature algorithm is SM3WithSM2.

    The encryption algorithm of the server-side certificate must match that of the sub-CA certificate. The key length can differ. For example, if the sub-CA certificate uses RSA_2048, the server-side certificate must use RSA_1024, RSA_2048, or RSA_4096.

    Note

    Call DescribeCACertificate to check the key algorithm of the sub-CA certificate.

    RSA_2048
    ParentIdentifier

    string

    Yes

    Unique identifier of the sub-CA certificate that issues this certificate.

    Note

    Call DescribeCACertificateList to query the unique identifier of the sub-CA certificate.

    Note

    • If you set Days, BeforeTime, and AfterTime together, the validity period uses the value of Days.

    • The server-side certificate validity period cannot exceed that of the sub-CA certificate. Call DescribeCACertificate to check the sub-CA certificate validity period.
