DefaultCryptoMaterialsManager (aws-encryption-sdk-java 2.3.2 API)

java.lang.Object
- com.amazonaws.encryptionsdk.DefaultCryptoMaterialsManager

All Implemented Interfaces:

CryptoMaterialsManager
```
public class DefaultCryptoMaterialsManager
extends Object
implements CryptoMaterialsManager
```
The default implementation of CryptoMaterialsManager, used implicitly when passing a MasterKeyProvider to methods in AwsCrypto.
This default implementation delegates to a specific MasterKeyProvider specified at construction time. It also handles generating trailing signature keys when needed, placing them in the encryption context (and extracting them at decrypt time).

    Description copied from interface: CryptoMaterialsManager
    
    Prepares materials for an encrypt request. The resulting materials result must have a cleartext data key and (if applicable for the crypto algorithm in use) a trailing signature key.
    The encryption context returned may be different from the one passed in the materials request, and will be serialized (in cleartext) within the encrypted message.
