Key Management APIs

API	Description
Creating a CMK	Creates a CMK.
Enabling a CMK	Enables a CMK. Only an enabled CMK can be used.
Disabling a CMK	Disables a CMK. A disabled CMK cannot be used.
Scheduling the Deletion of a CMK	Schedules the deletion of a specific key. The deletion can be scheduled 7 to 1096 days in advance. After a key is deleted, the data encrypted using the key cannot be decrypted.
Canceling the Scheduled Deletion of a CMK	Cancels a scheduled deletion of a key. Once the deletion is cancelled, the key can be used.
Querying the List of CMKs	Queries the list of all CMKs.
Querying the Information About a CMK	Queries details of a specified key.
Creating a Random Number	Generates a 512-bit random number.
Creating a DEK	Creates a DEK. A returned result includes the plaintext and the ciphertext of a DEK.
Creating a Plaintext-Free DEK	Creates a plaintext-free DEK, that is, the returned result of this API includes only the ciphertext of the DEK.
Encrypting a DEK	Uses a specified CMK to encrypt a DEK.
Decrypting a DEK	Uses a specified CMK to decrypt a DEK.
Querying the Number of Instances	Obtains the number of created CMKs, excluding the default master keys.
Querying the Quota of a User	Queries the total quota of CMKs available and the usage information, excluding the default master keys.
Changing the Alias of a CMK	Changes the alias of a CMK.
Changing the Description of a CMK	Changes the description of a CMK.
Obtaining CMK Import Parameters	Obtains necessary parameters to import a key, including an import token and an encryption public key.
Importing CMK Material	Imports the key material of a specified key.
Deleting CMK Material	Deletes the key material of a specified key.
Enabling Rotation for a CMK	Enables the rotation of a CMK. Default master keys and imported keys do not support the rotation function.
Changing the Rotation Interval for a CMK	Changes the rotation interval for a CMK.
Disabling Rotation for a CMK	Disables the rotation of a CMK.
Querying the Rotation Status of a CMK	Queries the rotation status of a CMK.
