    Certificate Management Service:CreateServerCertificateWithCsr

    Last Updated:Dec 22, 2025

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

    Operation description

    Before you call this operation, you must create a root certificate authority (CA) certificate by calling CreateRootCACertificate and a subordinate CA certificate by calling CreateSubCACertificate. Only subordinate CA certificates can issue server-side certificates.

    QPS limit

    This operation has a queries per second (QPS) limit of 10 calls per second for each user. API calls that exceed this limit are throttled. This may affect your business operations. We recommend that you plan your calls accordingly.

    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.

    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.

    Parameter

    Type

    Required

    Description

    Example
    Csr

    string

    Yes

    The content of the CSR. Use OpenSSL or Keytool to generate a CSR file. For more information, see How to create a CSR file.

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

    string

    No

    The additional domain names or IP addresses for the server-side certificate. This lets you apply the certificate to multiple domain names or IP addresses.

    Enter multiple domain names and IP addresses. To enter multiple values, separate them with a comma (,).

    Organization

    string

    No

    The name of the organization. Default value: Alibaba Inc.

    阿里云
    OrganizationUnit

    string

    No

    The name of the department. Default value: Alibaba Cloud CDN.

    IT
    Country

    string

    No

    The country code. For example, CN.

    CN
    CommonName

    string

    No

    The common name of the certificate. Chinese characters, letters, and other characters are supported.

    Note

    If you set the Csr parameter, the common name from the CSR file is used.

    mtcsq.com
    State

    string

    No

    The name of the province or state where the organization is located. Chinese characters, letters, and other characters are supported. The default value is the province or state of the organization that is associated with the issuing subordinate CA certificate.

    Zhejiang
    Locality

    string

    No

    The name of the city where the organization is located. Chinese characters, letters, and other characters are supported. The default value is the city of the organization that is associated with the issuing subordinate CA certificate.

    Hangzhou
    Algorithm

    string

    No

    The key algorithm of the server-side certificate. The key algorithm is in the <encryption algorithm>_<key length> format. Valid values:

    • RSA_1024: The signature algorithm is Sha256WithRSA.

    • RSA_2048: The signature algorithm is Sha256WithRSA.

    • RSA_4096: The signature algorithm is Sha256WithRSA.

    • ECC_256: The signature algorithm is Sha256WithECDSA.

    • ECC_384: The signature algorithm is Sha256WithECDSA.

    • ECC_512: The signature algorithm is Sha256WithECDSA.

    • SM2_256: The signature algorithm is SM3WithSM2.

    The encryption algorithm of the server-side certificate must be the same as the encryption algorithm of the subordinate CA certificate. The key length can be different. For example, if the key algorithm of the subordinate CA certificate is RSA_2048, the key algorithm of the server-side certificate must be RSA_1024, RSA_2048, or RSA_4096.

    Note

    Call DescribeCACertificate to query the key algorithm of a subordinate CA certificate.

    RSA_2048
    ParentIdentifier

    string

    Yes

    The unique identifier of the subordinate CA certificate that issues the certificate.

    Note

    Call DescribeCACertificateList to query the unique identifiers of subordinate CA certificates.
