John the
Ripper
This file is also used to load passwords that you already
cracked, when you run John the next time.
To retrieve the cracked passwords, run
john -show passwd
While cracking, you can press any key for status, or press
Ctrl+C to abort the session, saving point information
to a file (~/restore by default). By the way, if you press
Ctrl+C twice John will abort immediately without
saving. The point information is also saved every 10
minutes (configurable in the configuration file,
~/john.ini) in case of a crash.
To continue an interrupted session, run
john -restore
Anyway, you probably should have a look at doc/OPTIONS
for a list of all the command line options, and at
doc/EXAMPLES for more John usage examples with
other cracking modes.
Options:
You can list any number of password files on John??™s
command line, and also specify some of the following
options (all of them are case sensitive, but can be
abbreviated; you can also use the GNU-style long
options syntax):
-single "single crack" mode Enables the ???single crack???
mode, using rules from [List.Rules:Single].
-wordfile:FILE wordlist mode Read words from FILE,
-stdin, or stdin.
These options are used to enable the wordlist mode:
-rules enable rules for wordlist mode Enables wordlist
rules that are read from [List.
