Class HybridDecryptWrapper

java.lang.Object

com.google.crypto.tink.hybrid.HybridDecryptWrapper

All Implemented Interfaces:

PrimitiveWrapper<HybridDecrypt,HybridDecrypt>

public class HybridDecryptWrapper
extends Object
implements PrimitiveWrapper<HybridDecrypt,HybridDecrypt>

The implementation of PrimitiveWrapper<HybridDecrypt>.

The returned primitive works with a keyset (rather than a single 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 Summary

Modifier and Type	Method and Description
Class<HybridDecrypt>	getInputPrimitiveClass() Returns the primitive class object of the primitive used to create B.
Class<HybridDecrypt>	getPrimitiveClass() Returns the primitive class object of the primitive managed.
static void	register() Register the wrapper within the registry.
static void	registerToInternalPrimitiveRegistry(PrimitiveRegistry.Builder primitiveRegistryBuilder) registerToInternalPrimitiveRegistry is a non-public method (it takes an argument of an internal-only type) registering an instance of HybridDecryptWrapper to the provided PrimitiveRegistry.Builder.
HybridDecrypt	wrap(PrimitiveSet<HybridDecrypt> primitives) Wraps a PrimitiveSet and returns a single instance.

Method Detail

wrap

public HybridDecrypt wrap(PrimitiveSet<HybridDecrypt> 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<HybridDecrypt,HybridDecrypt>

Throws:

GeneralSecurityException

getPrimitiveClass

public Class<HybridDecrypt> 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<HybridDecrypt,HybridDecrypt>

getInputPrimitiveClass

public Class<HybridDecrypt> 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<HybridDecrypt,HybridDecrypt>

register

public static void register()
                     throws GeneralSecurityException

Register the wrapper within the registry.

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

Throws:

GeneralSecurityException

registerToInternalPrimitiveRegistry

public static void registerToInternalPrimitiveRegistry(PrimitiveRegistry.Builder primitiveRegistryBuilder)
                                                throws GeneralSecurityException

registerToInternalPrimitiveRegistry is a non-public method (it takes an argument of an internal-only type) registering an instance of HybridDecryptWrapper to the provided PrimitiveRegistry.Builder.

Throws:

GeneralSecurityException
