I have a system that I am taking over support for that is running an older version of Sybase, version on HP-UX 11.11. Upgrading the database is not an option. However, the issue of the data not being encrypted came up the other day and the client would like to know there options. My understanding with Sybase is we can only encrypt the data at the column level. Is there an option to encrypt the entire database? Are there extra licensing requirements needed to enable encryption? Any issues that anyone knows of with encryption on this version of Sybase?

My apologies if these are basic questions, normally I support DB2 and Oracle.
