Hi Aleksey,

I did not yet look at the code, so I'll probably reply with some more
thoughts/remarks later.

Do you handle --config=other.conf?
If there are multiple --config= (or -conf: ---) options on the command
line, john will use the last one.
But we could also treat this as a bug in john, and write a patch so that
specifying multiple --config options on the command line results in an

We probably need to handle includes in some way.
Another approach would be to add some functionality into john which
resolves the contents of the section(s) needed for a certain attack
so that it can be used by a script.

Something like

./john (parameters and options that specify an attack) --generate-config

which would write a minimum config file to stdout, including all the
sections (and either resolving or including sub-sections) needed for the

I am not sure how hard to implement this would be, but I assume it
shouldn't be too hard.
If such a functionality exists, You could upload an attack-specific
config file instead.
To further enhance this idea, --generate-config could also add
information about which files (not counting the password hash files)
will be needed for the attack into comments at the begin of the config file.
(If --generate-config doesn't resolve include files, all the required
includes need to be listed as files required for the attack in the
comments at the begin of the generated config file.)

But all this is certainly stuff to be considered after the contest.

Will do, but this will take some more time.
