Journal receive encryption

After a discution with a Db2 expert about RCAC implemenation, it appears that after an update of a journalized table, the corresponding journal entry can be fully displayed with a simple DSPJRN command. 

Is it possible to add a new option at the creation of a journal and/or of a journal receiver that implement the encryption of a journal receiver ? 

This option could be used or not depending of the usage of the journal receivers (replication, auditing, duplication of table in real time, ...) and let to the customer needs.

    IBM does not intend to provide a solution to this Idea at this time, so it is being closed.

    The data written to the journal is an exact image of what is written to the file. Any change to what is recorded in the journal would be expensive to implement and have performance implications. For these reasons, IBM will not be addressing this Idea in the near future.

    To have journal images contain non-clear values today, the best solution we have is to define a field procedure to modify the sensitive data so the data is not "in the clear" on disk nor in the data journal. We are aware of several clients who use both field procedures and RCAC to secure their data.

    The DISPLAY_JOURNAL table function returns the data honoring the RCAC rules. You could consider tightening authority on the DSPJRN CL command and accessing the journal data through the SQL interface.
