SAP GUI SNC client encryption with commoncryptolib

Dear experts,

I am searching a lot in this Topic but I am not sure if it is possible and allowed by SAP to encrypt the communication between SAP GUI and AS ABAP using the commoncryptolib without SAP Netweaver Single-Sign-On. Important for me is encrypted communication and not the single sign on Feature. As far as possible the product should be without additional costs so I think commoncryptolib would be fine.

Can somebody give me a link to a tutorial how to configure SNC Client encryption between SAP GUI and AS ABAP (please not SAP help http://help.sap.com/saphelp_nw74/helpdata/en/b9/0dfa4a0457487bb0e59d304eb1a79a/content.htm?frameset=/en/b9/0dfa4a0457487bb0e59d304eb1a79a/frameset.htm&current_toc=/en/cd/a3937849b043509786c5b42171e5d3/plain.htm&node_id=132&show_children=true#jump132 )

I tried the SAP help Information and had Problems with the Active Directory Integration which is only described rudimentary).

Also in my Scenario I had multiple Domains in different Locations which cannot be integrated in trusted Domains. So a solution without active Directory would be fine. Is this possible?

Thank you very much in advance.

Kind regards, Basti
