Class LiteralEncryptionInterceptor

java.lang.Object

xdi2.messaging.container.impl.AbstractExtension<CONTAINER>

xdi2.messaging.container.interceptor.impl.AbstractInterceptor<MessagingContainer>

xdi2.messaging.container.interceptor.impl.encryption.LiteralEncryptionInterceptor

All Implemented Interfaces:

Cloneable, Extension<MessagingContainer>, Interceptor<MessagingContainer>, OperationInterceptor, TargetInterceptor, Prototype<LiteralEncryptionInterceptor>

public class LiteralEncryptionInterceptor
extends AbstractInterceptor<MessagingContainer>
implements OperationInterceptor, TargetInterceptor, Prototype<LiteralEncryptionInterceptor>

This interceptor encrypts literals in an incoming XDI message, and decrypts literals in the XDI message result. It invokes an instance of LiteralCryptoService to perform encryption and decryption.
