Class PrivateKeyManagerImpl<PrimitiveT,KeyProtoT extends com.google.protobuf.MessageLite,PublicKeyProtoT extends com.google.protobuf.MessageLite>

java.lang.Object

com.google.crypto.tink.KeyManagerImpl<PrimitiveT,KeyProtoT>

com.google.crypto.tink.PrivateKeyManagerImpl<PrimitiveT,KeyProtoT,PublicKeyProtoT>

All Implemented Interfaces:

KeyManager<PrimitiveT>, PrivateKeyManager<PrimitiveT>

@Alpha
public class PrivateKeyManagerImpl<PrimitiveT,KeyProtoT extends com.google.protobuf.MessageLite,PublicKeyProtoT extends com.google.protobuf.MessageLite>
extends KeyManagerImpl<PrimitiveT,KeyProtoT>
implements PrivateKeyManager<PrimitiveT>

Implementation of the PrivateKeyManager interface based on an PrivateKeyTypeManager and the corresponding public key manager, implemented by an KeyTypeManager.

Choosing PrimitiveT equal to Void is valid; in this case the functions KeyManagerImpl.getPrimitive(com.google.protobuf.ByteString) will throw if invoked. TODO(tholenst) Reduce visibility to package visible once all managers have been migrated.
