Class HybridEncryptWrapper

java.lang.Object

com.google.crypto.tink.hybrid.HybridEncryptWrapper

All Implemented Interfaces:

PrimitiveWrapper<HybridEncrypt,HybridEncrypt>

public class HybridEncryptWrapper
extends Object
implements PrimitiveWrapper<HybridEncrypt,HybridEncrypt>

The implementation of PrimitiveWrapper<HybridEncrypt>.

The returned 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.

Method Summary

Modifier and Type	Method and Description
Class<HybridEncrypt>	getInputPrimitiveClass() Returns the primitive class object of the primitive used to create B.
Class<HybridEncrypt>	getPrimitiveClass() Returns the primitive class object of the primitive managed.
static void	register() Register the wrapper within the registry.
HybridEncrypt	wrap(PrimitiveSet<HybridEncrypt> primitives) Wraps a PrimitiveSet and returns a single instance.

Method Detail

wrap

public HybridEncrypt wrap(PrimitiveSet<HybridEncrypt> 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<HybridEncrypt,HybridEncrypt>

getPrimitiveClass

public Class<HybridEncrypt> 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<HybridEncrypt,HybridEncrypt>

getInputPrimitiveClass

public Class<HybridEncrypt> 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<HybridEncrypt,HybridEncrypt>

register

public static void register()
                     throws GeneralSecurityException

Register the wrapper within the registry.

This is required for calls to Keyset.getPrimitive with a HybridEncrypt argument.

Throws:

GeneralSecurityException
