Tomohito Nakayama commented on DERBY-1301:
------------------------------------------

I found description of DSS Encryption at page 315 of DRDA, Version 3, Volume 3, Distributed
Data Management (DDM) Architecture.

In that description, there exists what may concerns about this issue. 

===
For Encrypted Object DSS, if the object is segmented at Layer A to accommodate transmission
buffer restrictions (or for any other reason), then the segmented object must be combined
and decrypted as a single object.
===

Information for length of object, provided by encrypting side, 
would be helpful information when conbining it at decrypting side.
However, spec does not say that it is impossible to handle an Encrypted Object DSS in Layer
B streaming.

It would be a matter of implementation whether to conduct layer B streaming for Encrypted
Object DSS ...

> Patch developed in DERBY-326 acted on streaming from server to client.
> I think similar modification should be done from client to server too.
