> I am running 3.1.0-FINAL and have observed that message headers are not
> being encrypted even though the "encrypt_entire_message" option is set to
> true.  After stepping through the code I suspect that the headers are being
> appended to the output stream that is used at the TCP layer.
> Specifically...
> org.jgroups.protocols.ENCRYPT.sendDown(Event evt) will encrypt the message
> (including headers) and send down the stack via this block...
> private void sendDown(Event evt) throws Exception {
> ...
>         EncryptHeader hdr=new EncryptHeader(EncryptHeader.ENCRYPT, getSymVersion());
>         hdr.encrypt_entire_msg=this.encrypt_entire_message;
>         if(encrypt_entire_message) {
>             byte[] serialized_msg=Util.streamableToByteBuffer(msg);
>             byte[] encrypted_msg=encryptMessage(symEncodingCipher,
>                                                 serialized_msg,
>                                                 0,
>                                                 serialized_msg.length);
>             Message tmp=msg.copy(false); // we need to preserve headers which may already be present
>             tmp.setBuffer(encrypted_msg);
>             if(tmp.getSrc() == null)
>                 tmp.setSrc(local_addr);
>             tmp.putHeader(this.id, hdr);
>             passItDown(new Event(Event.MSG, tmp));
>             return;
>         }
> ...
> }
> Note that the unencrypted headers are preserved even though the encrypted
> headers are included in "encrypted_msg".
> Later on, org.jgroups.protocols.TP.writeMessage(Message msg, DataOutputStream dos, boolean multicast) will call
> Message.writeTo(DataOutput) to build the message that is sent.  The problem
> seems to be that Message.writeTo(DataOutput) will include the encrypted
> byte[] (expected) but also include the unencrypted headers that were
> preserved.
