Is it possible to disable compression in SapGui client for Java?

[Former Member]

Subj. I know it is possible to do it in native Windows-client by setting "TDW_NOCOMPRESS" environment variable to 1.

Hello 4elovo,

It's really not recommended to switch of the compression with

TDW_NOCOMPRESS as you can read passwords and so on in clear text!

Compression is not encryption. It provides no security at all. And SAP admits it.

Hello,

in case you are interested in having an encrypted communication:

Certified products for SNC can be found at

http://www.sap.com/partners/directories/SearchSolution.epx

searching for Certification category "Secure network communication".

You might need to contact the vendor to see which platforms they support.

Thanks, I know it, this is not the thing I asked about. Let me repeat:

Hello,

your previous comment sounded like a complaint, that your are lacking encryption, because the compression used for the communication between SAP GUI and Web AS ABAP does not provide it.

Regarding SAP GUI for Java, I am not aware of an option to disable the compression. Curious question: why would you need that?

Rolf-Martin, I've written comment about encryption in answer to Jude Bradley's pretty naive comment about reading passwords in clear text.

I was very surprised when I knew that passwords are SO unprotected. It is a huge security hole. Of course, there is SNC, but imho, such simple but important issue must be solved without any additional products.

To fulfil your curiosity, I'm interested in both expanding SAPGui for Java functionality and researching sap security.

Hello,

apologizes for the misunderstanding.

Regarding security, you might want to have a look at the forum and http://www.sdn.sap.com/irj/sdn/security.

Back to the original matter, I can tell that modifying or extending the SAP GUI functionality on communication protocol level is quite challenging. The protocol is not published and a binary protocol.

Depending what your intention is, you might want to have a look at [GuiXT|http://www.guixt.com/].

Another approach is to write your own controls for SAP GUI, see [How To Extend SAP GUI for Java with Your Own Java Bean |http://www.sdn.sap.com/irj/sdn/sap-gui?rid=/library/uuid/20e0536f-eaf4-2a10-319d-eb68f8e6cee3] on the [SAP GUI family page|http://www.sdn.sap.com/irj/sdn/sap-gui#section16].

Rolf-Martin Woersinger,

Thank you very much for the links. They might be useful for me.

Btw, I like challenges if I can solve them.

Best regards 😃
