How do you secure a UniData session using UniObjects for .net?

The documentation is severely lacking. The UniObjects for Java documentation has a whole chapter on SSL.

EDIT

The UniObjects .net documentation says this about the UniSession.EncryptionType property:

public int EncryptionType {get; set}

This property gets or sets the default encryption type for the session.

int is the token number for the encryption type, as follows:

0 – UniObjectsTokens.NO_ENCRYPT – No encryption. This is the default value.

1 – UniObjectsTokens.UV_ENCRYPT – Encrypt all data using internal database encryption.

If you set UV_ENCRYPT for a session, all data transferred between client and server is encrypted.

If I set my UniSession object’s EncryptionType property to 1 (UniObjectsTokens.UV_ENCRYPT), when I call my UniCommand’s Execute method, I get an IBMU2.UODOTNET.UniRPCPacketException that says

"[IBM U2][UODOTNET – UNIRPC][ErrorCode=81004] An argument was requested from the RPC that was of an invalid type"

    A very special person found this for me:

    I will report my findings. More input is welcome.

    EDIT

    After some research, I found that SSL with UniObjects will only work with Unidata 7.2. My school has 7.1 and we aren’t upgrading just yet. But a great developer at another school had a work around. We secured our Uniobjects communication using SSH Port Forwarding. Beautiful. On the computer that runs the uniobjects code, we used srvany.exe and an ssh client to create a windows service. In the ssh client we forward traffic from localhost:uniobjects_port to unidata_server:22.
