Domain name for API request: kms.intl.tencentcloudapi.com.
This API is used to verify a signature with an asymmetric key.
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 |
|---|---|---|---|
| Action | Yes | String | Common Params. The value used for this API: VerifyByAsymmetricKey. |
| Version | Yes | String | Common Params. The value used for this API: 2019-01-18. |
| Region | Yes | String | Common Params. For more information, please see the list of regions supported by the product. |
| KeyId | Yes | String | Unique identifier of the key |
| SignatureValue | Yes | String | Signature value, generated by calling the KMS signing API |
| Message | Yes | String | Message original text or message digest. If the message original text is provided, its length (before Base64 encoding) cannot exceed 4096 bytes. If the message digest is provided, its length (before Base64 encoding) must be 32 bytes. |
| Algorithm | Yes | String | Signature algorithm. Supported algorithms: SM2DSA, ECC_P256_R1, ECDSA384_SHA384, RSA_PSS_SHA_256, RSA_PKCS1_SHA_256, RSA_PSS_SHA_384, RSA_PKCS1_SHA_384, RSA_PSS_SHA_512, RSA_PKCS1_SHA_512, etc. For more supported algorithms, query them through the ListAlgorithms API. |
| MessageType | No | String | Message type: RAW or DIGEST. If not specified, RAW is used by default, indicating the message original text. |
| Parameter Name | Type | Description |
|---|---|---|
| SignatureValid | Boolean | Whether the signature is valid. true: valid; false: invalid. |
| RequestId | String | The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem. |
