方法详细资料

encryptionContext

public GenerateDataKeyRequest.Builder encryptionContext(Map<String,?> encryptionContext)

The JSON string that consists of key-value pairs.

If you specify this parameter, an equivalent value is required when you call the [Decrypt](~~28950~~) operation. For more information, see [EncryptionContext](~~42975~~).

keyId

public GenerateDataKeyRequest.Builder keyId(String keyId)

The ID of the CMK. The ID must be globally unique.

You can also set this parameter to an alias that is bound to the CMK. For more information, see [Alias overview](~~68522~~).

keySpec

public GenerateDataKeyRequest.Builder keySpec(String keySpec)

The type of the data key that you want to generate. Valid values:

* AES\_256: a 256-bit symmetric key * AES\_128: a 128-bit symmetric key > We recommend that you use the KeySpec or NumberOfBytes parameter to specify the length of a data key. If none of the parameters are specified, KMS generates a 256-bit data key. If both parameters are specified, KMS ignores the KeySpec parameter.

numberOfBytes

public GenerateDataKeyRequest.Builder numberOfBytes(Integer numberOfBytes)

The length of the data key that you want to generate. Unit: bytes.

Valid values: 1 to 1024. Default value: * If the KeySpec parameter is set to AES\_256, set the value of the NumberOfBytes parameter to 32. * If the KeySpec parameter is set to AES\_128, set the value of the NumberOfBytes parameter to 16.
