Domain name for API request: kms.tencentcloudapi.com.
This API is used to decrypt data with the specified private key that is encrypted with RSA asymmetric cryptographic algorithm. The ciphertext must be encrypted with the corresponding public key. The asymmetric key must be in Enabled
state for decryption.
A maximum of 200 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 |
