Class StreamingAeadWrapper

java.lang.Object

com.google.crypto.tink.streamingaead.StreamingAeadWrapper

All Implemented Interfaces:

PrimitiveWrapper<StreamingAead,StreamingAead>

public class StreamingAeadWrapper
extends Object
implements PrimitiveWrapper<StreamingAead,StreamingAead>

StreamingAeadWrapper is the implementation of PrimitiveWrapper for the StreamingAead primitive.

The returned primitive works with a keyset (rather than a single key). To encrypt a plaintext, it uses the primary key in the keyset. To decrypt, the primitive tries the enabled keys from the keyset to select the right key for decryption. All keys in a keyset of StreamingAead have type OutputPrefixType.RAW.

Method Detail

wrap

public StreamingAead wrap(PrimitiveSet<StreamingAead> primitives)
                   throws GeneralSecurityException

Description copied from interface: PrimitiveWrapper

Wraps a PrimitiveSet and returns a single instance.

This method gets called when a new primitive is created. primitiveSet is immutable. This has to be implemented when a new primitive type is added.

Specified by:

wrap in interface PrimitiveWrapper<StreamingAead,StreamingAead>

Returns:

a StreamingAead primitive from a keysetHandle.

Throws:

GeneralSecurityException

getPrimitiveClass

public Class<StreamingAead> getPrimitiveClass()

Description copied from interface: PrimitiveWrapper

Returns the primitive class object of the primitive managed. Used for internal management. Should be implemented as return P.class; when implementing a wrapper creating objects of type P.

Specified by:

getPrimitiveClass in interface PrimitiveWrapper<StreamingAead,StreamingAead>

getInputPrimitiveClass

public Class<StreamingAead> getInputPrimitiveClass()

Description copied from interface: PrimitiveWrapper

Returns the primitive class object of the primitive used to create B. Used for internal management. Should be implemented as return B.class;.

Specified by:

getInputPrimitiveClass in interface PrimitiveWrapper<StreamingAead,StreamingAead>

register

public static void register()
                     throws GeneralSecurityException

Throws:

GeneralSecurityException
