I don't search it yet, but I already have read that, IB/FB contain
"something" ;)

For a point to start the hunting:

- in <FB dir>/include/ibase.h you can see a constant for connect:
isc_dpb_encrypt_key, this is to isc_attach_database().

In Firebird source you can find it and see what it do ;)

Maybe a conditional compilation remove it from FB, like other non good
tested feature ?
