Class EncryptedTranscoder

java.lang.Object

org.apereo.spring.webflow.plugin.EncryptedTranscoder

All Implemented Interfaces:

Transcoder

public class EncryptedTranscoder
extends Object
implements Transcoder

Encodes an object by encrypting its serialized byte stream. Details of encryption are handled by an instance of CipherBean. Default ciphering mode is set to 128-bit AES in CBC mode with compression.

Optional gzip compression of the serialized byte stream before encryption is supported and enabled by default.
