Package com.google.crypto.tink.hybrid

Class HybridEncryptWrapper

java.lang.Object

com.google.crypto.tink.hybrid.HybridEncryptWrapper

All Implemented Interfaces:

PrimitiveWrapper<HybridEncrypt,HybridEncrypt>

public class HybridEncryptWrapper
extends java.lang.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 Detail

wrap

public HybridEncrypt wrap(KeysetHandleInterface keysetHandle,
                          MonitoringAnnotations annotations,
                          PrimitiveWrapper.PrimitiveFactory<HybridEncrypt> factory)
                   throws java.security.GeneralSecurityException

Description copied from interface: PrimitiveWrapper

Wraps a PrimitiveSet and returns a single instance.

This method gets called when a new primitive is created.

Specified by:

wrap in interface PrimitiveWrapper<HybridEncrypt,HybridEncrypt>

Throws:

java.security.GeneralSecurityException

getPrimitiveClass

public java.lang.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 java.lang.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 java.security.GeneralSecurityException

Register the wrapper within the registry.

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

Throws:

java.security.GeneralSecurityException

registerToInternalPrimitiveRegistry

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

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

Throws:

java.security.GeneralSecurityException
