Class DefaultCryptoMaterialsManager

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).

Method Detail

getMaterialsForEncrypt

public EncryptionMaterials getMaterialsForEncrypt(EncryptionMaterialsRequest request)

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.
