SSLEngine does not decrypt all the data

I am trying to use SSLengine with SocketChannels in non-blocking mode.

The handshake is done correctly but when i try to read & decrypt http posts from channelsocket, only the headers are decrypted and the body disapear:

<code>
int num=0;

            while(num==0){
                num=socketChannel.read(peerNetData);
                if(num==-1)
                    break;
            }

            if (num == -1) {
                System.out.println("channel closed");
            } else if (num == 0) {
                System.out.println("no bytes to read");
            } else {
                // Process incoming data

                peerNetData.flip();

                SSLEngineResult res = engine.unwrap(peerNetData, peerAppData);
               //return a ok status 

peerNetData.flip();
            peerAppData.flip();
            System.out.println(new String(peerNetData.array()));  
            System.out.println(new String(peerAppData.array()));  


</code>

when printing the encrypted data in peerNetData i am getting :

?>.//POST test HTTP/1.1 Cache-Control: no-cache Content-Length: 20 Content-Type: application/octet-stream Host: 192.168.X.X

?>.//?>.//?>.//?>.//?>.//?>.//?>.//?>.//?>.//?>.//?>.// <--- encrypted chars here

but when i print the decrypted data in peerAppData i am getting

POST test HTTP/1.1/ Cache-Control: no-cache Content-Length: 20 Content-Type: application/octet-stream Host: 192.168.X.X // and then three empty lines here.

is this a decryption problem with SSlengine??

Thanks

Also i would like to add that unwrap method return an OK status.

It could well be that the actual POST content was empty except for the 2 empty lines (one line is standard after the header, if I'm not mistaken). Because of PKCS#7 padding, at least 16 bytes of data (one block, 16 bytes for AES) will be encrypted at the minimum.

Besides that the data will also contain a MAC as SSL usually uses MAC-then-encrypt (also known as the wrong way around according to most).

So it may look like there is data, even if it is just overhead.
