Firebird File and Metadata Securitythe work around for such hacks is to simply build your own version of the server that bypasses the event or code which is preventing access. It is difficult to offer obscurity in an open source system. or whatever at such schemes because those are all about strong encryption. They are heavy with processing overhead and complication relating to keeping the security strong. A simple XOR against some known accurate at the time of writing but I cannot guarantee that there are no mistakes.
