DefaultCryptoMaterialsManager (Amazon S3 Encryption Client 4.0.0 API)

java.lang.Object
- software.amazon.encryption.s3.materials.DefaultCryptoMaterialsManager

All Implemented Interfaces:

CryptographicMaterialsManager
```
public class DefaultCryptoMaterialsManager
extends Object
implements CryptographicMaterialsManager
```
Default implementation of CryptographicMaterialsManager that uses a Keyring to obtain cryptographic materials. This CMM calls the keyring's onEncrypt and onDecrypt operations to prepare the cryptographic materials for each request.
