    Unanswered: DATA_ENCRYPT Authentication

    Warning: This post contains newbie material that may be offensive to some viewers. Viewer discretion is advised.

    A DB2 tutorial explains DATA_ENCRYPT authentication as follows:

    Authentication takes place on the server. The server accepts encrypted userids and passwords, and will encrypt the data. This operates the same way as SERVER_ENCRYPT, except the data is encrypted as well.
    This implies that encryption of the data takes place on the server, but I thought the point of encryption was to protect the data while being transferred from the client to the server. Can anyone elaborate on this?

    My understand to this is that the data and the userid/password will be geting encrypted by client and sent over wire to server where they are decrypted and finally verified .
    I may be wrong though

    may be this is not require no more becz it is a very old post

    DATA_ENCRYPT Specifies that the server accepts encrypted SERVER authentication schemes and the encryption of user data.

    The following user data is also encrypted when using this authentication type:
    SQL and XQuery* statements
    SQL program variable data
    Output data from the server processing of an SQL or XQuery* statement and including a description of the data
    Some or all of the answer set data resulting from a query
    Large object (LOB) data streaming
    SQLDA descriptors

    ( i know this is a very old post but as I was serching the same what u were searching may be this information will be helpful for a new person for db2 )
