That's not really the problem. I want to hide a clear text password in
that program (something like ssh-agent or gpg-agent; the last can be
straced, too :-() which I need for a database when the program runs.

Is there another way to do this? If the password is crypted, I need a
passphrase or something other to decrypt it again. Not really a solution
of the problem.

Therefore, it would be best, to hide it by preventing stracing of the
application to all users and root.

Ok, root could search for the password directly in the memory, but this
would be not as easy as a strace.


Kind regards,
Andreas Hartmann
