Creates an intermediate certificate authority (CA) certificate.
Operation description
You can call this operation to issue an intermediate certificate authority (CA) certificate by using an existing root CA certificate. Intermediate CA certificates can be used to issue client certificates and server certificates.
Before you call this operation, make sure that you have issued a root CA certificate by calling the [CreateRootCACertificate] operation.
Limits
You can call this operation up to 10 times per second per account. If the number of the calls per second exceeds the limit, throttling is triggered. As a result, your business may be affected. We recommend that you take note of the limit when you call this operation.

Request parameters
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| ParentIdentifier | string | Yes | The unique identifier of the root CA certificate. Note
You can call the [DescribeCACertificateList] operation to query the unique identifiers of all CA certificates.
| 1a83bcbb89e562885e40aa0108f5**** |
| CommonName | string | Yes | The common name or abbreviation of the organization. The value can contain letters. | Aliyun |
| OrganizationUnit | string | Yes | The name of the department or branch in the organization. The value can contain letters. | Security |
| Organization | string | Yes | The name of the organization that is associated with the intermediate CA certificate. You can enter the name of your enterprise or company. The value can contain letters. | Maizi Technology |
| Locality | string | Yes | The name of the city in which the organization is located. The value can contain letters. | Hangzhou |
| State | string | Yes | The name of the province or state in which the organization is located. The value can contain letters. | Zhejiang |
| CountryCode | string | No | The code of the country or region in which the organization is located. You can enter an alpha-2 or alpha-3 code. For example, you can use CN to indicate China and use US to indicate the United States. For more information about country codes, see the "Country codes" section in Manage company profiles. | CN |
| Algorithm | string | Yes | The type of the key algorithm of the intermediate CA. The key algorithm is in the
The encryption algorithm of an intermediate CA certificate must be consistent with the encryption algorithm of a root CA certificate. The length of the keys can be different. For example, if the key algorithm of the root CA certificate is RSA_2048, the key algorithm of the intermediate CA certificate must be RSA_1024, RSA_2048, or RSA_4096. Note
You can call the DescribeCACertificate operation to query the key algorithm of a root CA certificate.
| RSA_2048 |
| Years | integer | Yes | The validity period of the intermediate CA certificate. Unit: years. We recommend that you set this parameter to 5 to 10. Note
The validity period of the intermediate CA certificate cannot exceed the validity period of the root CA certificate. You can call the [DescribeCACertificate]operation to query the validity period of a root CA certificate.
| 5 |
| PathLenConstraint | integer | No | The path length constraint of the certificate. Default value: 0. | 0 |
| ExtendedKeyUsages | array | No | The extended key usages of the certificate. | |
| string | No | The extended key usage of the certificate. Valid values:
| serverAuth | |
| EnableCrl | boolean | No | Enable Crl Service.
| 1 |
| CrlDay | integer | No | CRL validity period: 1-365 days | 30 |
