Table 2 Request parameters

Parameter

Mandatory

Type

Description

key_id

Yes

String

36-byte ID of a CMK that matches the regular expression ^[0-9a-z]{8}-[0-9a-z]{4}-[0-9a-z]{4}-[0-9a-z]{4}-[0-9a-z]{12}$

Example: 0d0466b0-e727-4d9c-b35d-f84bb474a37f

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"}

plain_text

Yes

String

Plaintext data which is 1 to 4096 bytes in length and matches the regular expression ^.{1,4096}$. After being converted into a byte array, it is still 1 to 4096 bytes in length.
