Class MultipleProviderFactory

java.lang.Object

com.amazonaws.encryptionsdk.multi.MultipleProviderFactory

public class MultipleProviderFactory
extends Object

Constructs MasterKeyProviders which are backed by any number of other MasterKeyProviders. The returned provider will have the following properties:

• MasterKeyProvider.getMasterKeysForEncryption(MasterKeyRequest) will result in the union of all responses from the backing providers. Likewise,
• MasterKeyProvider.decryptDataKey(CryptoAlgorithm, Collection, Map) will succeed if and only if at least one backing provider can successfully decrypt the DataKeys.
• MasterKeyProvider.getDefaultProviderId() is delegated to the first backing provider.
• MasterKeyProvider.getMasterKey(String, String) will attempt to find the appropriate backing provider to return a MasterKey.

All methods in this factory return identical results and exist only for different degrees of type-safety.
