Domain name for API request: kms.tencentcloudapi.com.
This API is used to encrypt any data up to 4KB. It can be used to encrypt database passwords, RSA Key, or other small sensitive information. For application data encryption, use the DataKey generated by GenerateDataKey to perform local data encryption and decryption operations
A maximum of 300 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 Params. The value used for this API: Encrypt. |
Version | Yes | String | Common Params. The value used for this API: 2019-01-18. |
Region | No | String | Common Params. This parameter is not required for this API. |
KeyId | Yes | String | Globally unique ID of the CMK generated by calling the CreateKey API |
Plaintext | Yes | String | Encrypted plaintext data. This field must be Base64-encoded. The maximum size of the original data is 4 KB |
EncryptionContext | No | String | JSON string of key-value pair. If this parameter is specified, the same parameter needs to be provided when the Decrypt API is called. It is up to 1,024 characters |
Parameter Name | Type | Description |
---|---|---|
CiphertextBlob | String | Base64-encoded ciphertext, which is the encrypted information of the ciphertext and key. To get the plaintext, you need to pass in this field to the Decrypt API. |
KeyId | String | Globally unique ID of the CMK used for encryption |
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 use a CMK to encrypt data up to 4 KB.
