Logging plain passwords was only so that I can determine what
passwords are being sent to the server.
What I really need to do is to find out what password is being
sent from a particular windows client app that my client owns as it is
the only way to get access to their data.
It is kind of a messy situation but amounts to them being locked
out of their own servers by the network admins and so can't get
backups of their database.
The network admin people recompiled the app that I wrote and
changed the password.
I just need to be able to get copies of their data.
At least the situation has finally given me an excuse to get
involved in the firebird code because there are some ideas that I want
to try out when I get up to speed.
At the moment, I am thinking of just altering the windows client
dll to spit out the password as I assume that that is what does the
encrypting.
There are many ways to do what you want. First of all, you certainly can
get passwords from fbclient - see remote/interface.cpp. Next, you may
slightly change fbclient to make it convert dpb_password to
dpb_password_enc not calling crypt, just changing tag. And after it use
encrypted passwords from server. Or bruteforce encrypted passwords - on
modern computer this would not take too long, as I've said encryption is
old and poor.
But get ready that in FB3 the only option will be first one.
