You need to use Service API.

There are few options:
1. Use a 3rd party component. Which components do you have in Delphi
now? Perhaps you already have it.

2. Create "gsec" command line and spawn process to do it.

3. Use Firebird API. I'm not sure if you can do this from Delphi, since
it is in C.
