Domain name for API request: kms.tencentcloudapi.com.
Create a master key CMK (Custom Master Key) for user management data keys
A maximum of 100 requests can be initiated per second for this API.
The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
| Parameter Name | Required | Type | Description |
|---|---|---|---|
| Action | Yes | String | Common parameter. The value used for this API: CreateKey. |
| Version | Yes | String | Common parameter. The value used for this API: 2019-01-18. |
| Region | Yes | String | Common parameter. For more information, please see the list of regions supported by the product. |
| Alias | Yes | String | Unique alias that makes a key more recognizable and understandable. This parameter cannot be empty, can contain 1–60 letters, digits, -, and _, and must begin with a letter or digit. The kms- prefix is used for Tencent Cloud products. |
| Description | No | String | |
| KeyUsage | No | String | Key purpose. The default value is ENCRYPT_DECRYPT (creating a symmetric key for encryption and decryption). Other valid values include ASYMMETRIC_DECRYPT_RSA_2048 (creating an RSA2048 asymmetric key for encryption and decryption) and ASYMMETRIC_DECRYPT_SM2 (creating an SM2 asymmetric key for encryption and decryption). |
| Type | No | Integer | Specifies the key type. Default value: 1. Valid value: 1 - default type, indicating that the CMK is created by KMS; 2 - EXTERNAL type, indicating that you need to import key material. For more information, please see the GetParametersForImport and ImportKeyMaterial API documents. |
| Parameter Name | Type | Description |
|---|---|---|
| KeyId | String | Globally unique CMK ID |
| Alias | String | Alias that makes a key more recognizable and understandable |
| CreateTime | Integer | Key creation time in UNIX timestamp format |
| Description | String | CMK description |
| KeyState | String | CMK status |
| KeyUsage | String | CMK usage |
| TagCode | Integer | Tag operation return code. 0: success; 1: internal error; 2: business processing error |
| TagMsg | String | Tag operation return information |
| RequestId | String | The unique request ID, which is returned for each request. RequestId is required for locating a problem. |
This example shows you how to create a CMK used for data key management. The CMK can be used in other APIs to create data keys, perform encryption and decryption, and do more.
