Requests¶
Parameter | Mandatory | Type | Description |
---|---|---|---|
cipher_text | Yes | String | Ciphertext of encrypted data. The value is the cipher_text value in the data encryption result that matches the regular expression ^[0-9a-zA-Z+/=]{188,5648}$. |
encryption_context | No | Object | Key-value pairs with a maximum length of 8192 characters. This parameter is used to record resource context information, excluding sensitive information, to ensure data integrity. If this parameter is specified during encryption, it is also required for decryption. Example: {"Key1":"Value1","Key2":"Value2"} |
sequence | No | String | 36-byte serial number of a request message Example: 919c82d4-8046-4722-9094-35c3c6524cff |
