Hi, Demian
This awk one-liner will produce very long wordlist, so it depends how
much of free space do you want to waste ;-)
It could be |-ed to john, so no space would be wasted, but I don't know
how fast it will be. If you pre-process the wordlist, it will took a lot
of free space if not compressed, but john will be able to resume after
abort. You could also pre-process the wordlist and gzip it, then use
e.g. zcat to pipe it to john, if you don't like awk. If you decide to
use awk command |-ed to john or decompress wordlist, then I don't know
if john will be able to resume after abort or crash. Maybe magnum will know.
Before you go back to Incremental mode, have you tried Markov mode?
Best Regards
