Class EncryptedTranscoder

  • All Implemented Interfaces:
    Transcoder
    public class EncryptedTranscoder
extends java.lang.Object
implements Transcoder
    Encodes an object by encrypting its serialized byte stream. Details of encryption are handled by an instance of CipherBean.

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

    Since:
    6.1
