Class DeterministicAeadWrapper

java.lang.Object

com.google.crypto.tink.daead.DeterministicAeadWrapper

All Implemented Interfaces:

PrimitiveWrapper<DeterministicAead,DeterministicAead>

public class DeterministicAeadWrapper
extends Object
implements PrimitiveWrapper<DeterministicAead,DeterministicAead>

The implementation of PrimitiveWrapper<DeterministicAead>.

The created primitive works with a keyset (rather than a single key). To encrypt a plaintext, it uses the primary key in the keyset, and prepends to the ciphertext a certain prefix associated with the primary key. To decrypt, the primitive uses the prefix of the ciphertext to efficiently select the right key in the set. If the keys associated with the prefix do not work, the primitive tries all keys with OutputPrefixType.RAW.

Method Detail

wrap

public DeterministicAead wrap(PrimitiveSet<DeterministicAead> primitives)

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<DeterministicAead,DeterministicAead>

getPrimitiveClass

public Class<DeterministicAead> 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<DeterministicAead,DeterministicAead>

getInputPrimitiveClass

public Class<DeterministicAead> 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<DeterministicAead,DeterministicAead>

register

public static void register()
                     throws GeneralSecurityException

Throws:

GeneralSecurityException
