Last updated: 2023-08-07 17:45:17

1. API Description

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.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

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: AsymmetricRsaDecrypt.
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 Unique CMK ID
Ciphertext Yes String Base64-encoded ciphertext encrypted with PublicKey
Algorithm Yes String Corresponding algorithm when a public key is used for encryption. Valid values: RSAES_PKCS1_V1_5, RSAES_OAEP_SHA_1, RSAES_OAEP_SHA_256

3. Output Parameters

Parameter Name Type Description
KeyId String Unique CMK ID
Plaintext String Base64-encoded plaintext after decryption
RequestId String The unique request ID, which is returned for each request. RequestId is required for locating a problem.
