com.amazonaws.services.s3.model.CryptoConfiguration

public class CryptoConfiguration
extends Object

Stores configuration parameters that will be used during encryption and decryption by the Amazon S3 Encryption Client. With this object, you can set the encryption client to use Instruction Files or Object Metadata for storing encryption information. You can also specify your own crypto provider to be used during encryption and decryption.
