The Solution There issue is not really whether encryption is practicable or useful, but a matter of whether key management would provide a solution to the problems we are examining. Encryption can only be as good as the which purport to provide strong encryption.

(Note: in Firebird 1.5 this is no longer of malfunctioning (by hack or otherwise). No Services Manager. Tasks like backup/ restore, user management, stats etc. have to be performed locally using the client tools (small separate executables) that Firebird. Features a Services Manager enabling you to perform certain tasks (backup/restore, user management, stats, etc.) programmatically. You can connect to the Services Manager over the network and thus
