Subject: Johnny: core/jumbo differences
I've tried to write down exhaustive list of differences between john
core and john jumbo. I don't know everything, so feel free to comment.
This list does not cover usage of the differences in Johnny. I'll make
a follow up with ideas.
Thanks!

* Common CLI options without differences
--incremental[=MODE] "incremental" mode [using section MODE]
--external=MODE external mode or word filter
--stdout[=LENGTH] just output candidate passwords [cut at LENGTH]
--restore[=NAME] restore an interrupted session [called NAME]
--session=NAME give a new session the NAME
--status[=NAME] print status of a session [called NAME]
There is a point about session names related to --fork/--node: there
are multiple session files with number of node in names.

--make-charset=FILE make a charset, FILE will be overwritten
--make-charset=FILE make a charset file. It will be overwritten
(core, then jumbo; only descriptions are different)
--test[=TIME] run tests and benchmarks for TIME seconds each
--users=[-]LOGIN|UID[,..] [do not] load this (these) user(s) only
--groups=[-]GID[,..] load users [not] of this (these) group(s) only
--shells=[-]SHELL[,..] load users with[out] this (these) shell(s) only
--save-memory=LEVEL enable memory saving, at LEVEL 1..3
--node=MIN[-MAX]/TOTAL this node's number range out of TOTAL count
--fork=N fork N processes
* Common CLI Options
The format:
core option
jumbo option
comments
----------------------------------------
--single "single crack" mode
--single[=SECTION] "single crack" mode
It is possible to choose Rules section to run with single mode.
[List.Rules:Single] is the default in both versions (so --single is
equivalent to --single=Single; though parameters are not case
sensitive).
----------------------------------------
--wordlist=FILE --stdin wordlist mode, read words from FILE or stdin
--wordlist[=FILE] --stdin wordlist mode, read words from FILE or stdin
--pipe like --stdin, but bulk reads, and allows rules
$ ./core-1.8.0/run/john --wordlist ~/d/t.pw
Option requires a parameter: "--wordlist"
The default wordlist is used by default in jumbo:
[Options]
# Wordlist file name, to be used in batch mode
Wordlist = $JOHN/password.lst
Also jumbo has --stdin and --pipe options to read candidates from
standard input.
----------------------------------------
--rules enable word mangling rules for wordlist mode
--rules[=SECTION] enable word mangling rules for wordlist modes
$ ./core-1.8.0/run/john --rules=NT --wordlist=~/d/t.pw ~/d/t.pw
Extra parameter for option: "--rules=NT"
Core does not allow rules section to be specified. Both versions
default to [List.Rules:Wordlist]
----------------------------------------
--show show cracked passwords
--show[=LEFT] show cracked passwords [if =LEFT, then uncracked]
In jumbo --show can print remaining hashes but it drops dupes (when
there is 1 canonical hash for 2 users and the hash is in different
forms and/or there are different gecos).
----------------------------------------
--salts=[-]N load salts with[out] at least N passwords only
--salts=[-]COUNT[:MAX] load salts with[out] COUNT [to MAX] hashes
----------------------------------------
--format=NAME force hash type NAME: descrypt/bsdicrypt/md5crypt/
bcrypt/LM/AFS/tripcode/dummy/crypt
--format=NAME force hash of type NAME. The supported formats can
be seen with --list=formats and --list=subformats
Format list is much larger in jumbo, also it is possible to specify
hash type for generic crypt through --subformat option.
* Jumbo-only CLI options
--loopback[=FILE] like --wordlist, but fetch words from a .pot file
--dupe-suppression suppress all dupes in wordlist (and force preload)
--prince[=FILE] PRINCE mode, read words from FILE
--encoding=NAME input encoding (eg. UTF-8, ISO-8859-1). See also
doc/ENCODING and --list=hidden-options.
--mask=MASK mask mode using MASK
--markov[=OPTIONS] "Markov" mode (see doc/MARKOV)
--pot=NAME pot file to use
--list=WHAT list capabilities, see --list=help or doc/OPTIONS
--help print usage summary, just like running the command
without any parameters
--config=FILE use FILE instead of john.conf or john.ini
--mem-file-size=SIZE size threshold for wordlist preload (default 5 MB)
--format=CLASS valid classes: dynamic, cpu
--subformat=FORMAT pick a benchmark format for --format=crypt
--mkpc=N request a lower max. keys per crypt
--min-length=N request a minimum candidate length
--max-length=N request a maximum candidate length
--costs=[-]C[:M][,...] load salts with[out] cost value Cn [to Mn] for
tunable cost parameters, see doc/OPTIONS
(comma separated list of values/ranges per param.)
--field-separator-char=C use 'C' instead of the ':' in input and pot files
--fix-state-delay=N performance tweak, see doc/OPTIONS
--nolog disables creation and writing to john.log file
--log-stderr log to screen instead of file
--bare-always-valid=C if C is 'Y' or 'y', then the dynamic format will
always treat bare hashes as valid
--progress-every=N emit a status line every N seconds
--crack-status emit a status line whenever a password is cracked
--keep-guessing try more candidates for cracked hashes (ie. search
for plaintext collisions)
--max-run-time=N gracefully exit after this many seconds
--regen-lost-salts=N regenerate lost salts (see doc/OPTIONS)
--mkv-stats=FILE "Markov" stats file (see doc/MARKOV)
--reject-printable reject printable binaries
--verbosity=N change verbosity (1-5, default 3)
--skip-self-tests skip self tests
--stress-test[=TIME] loop self tests forever
--input-encoding=NAME input encoding (alias for --encoding)
--internal-encoding=NAME encoding used in rules/masks (see doc/ENCODING)
--target-encoding=NAME output encoding (used by format, see doc/ENCODING)
PRINCE mode options:
--prince-loopback[=FILE] fetch words from a .pot file
--prince-elem-cnt-min=N minimum number of elements per chain (1)
--prince-elem-cnt-max=N maximum number of elements per chain (8)
--prince-skip=N initial skip
--prince-limit=N limit number of candidates generated
--prince-wl-dist-len calculate length distribution from wordlist
instead of using built-in table
--prince-wl-max=N load only N words from input wordlist
--prince-case-permute permute case of first letter
--prince-mmap memory-map infile (not available when permuting case)
--prince-keyspace just show total keyspace that would be produced
(disregarding skip and limit)
Also there should be options for rexgen and other things not compiled
in my john:
OpenMPI support (default disabled) .......... no
OpenMP support .............................. no
OpenCL support .............................. no
CUDA support ................................ no
Experimental code ........................... no
Rexgen (extra cracking mode) ................ no
Memdbg memory debugging settings ............ disabled
AddressSanitizer ("ASan") ................... disabled
* Config file
In Jumbo config files may include other files. Core john has only one
file.
John built from sources searches config file (and other files) in run/
directory, john installed from package most usually looks into ~/.john
and /etc/john . While distros usually use john core, there distros
with jumbo. Also this behaviour may depend on distro.
With jumbo, you can get path to the folder with --list=build-info option:
$ jumbo/run/john --list=build-info
[...]
$JOHN is jumbo/run/
[...]
* Utilities and tools
In core
john - john
mailer - "script to send mail to all users whose passwords got cracked."
makechr - utility to make .chr files (incremental mode) from current .pot
relbench - statistics for benchmarks
unafs
unique - filter to remove dupes in wordlist saving order
unshadow
unafs and unshadow may fall into *2john category.
BTW Jumbo has bash auto-completions.
In jumbo there are various utilities:
*2john converters (including symlinks):
These tools usually read file(s) and print hashes to stdout in a form
john understands them. Some utilities perform quite non-trivial
parsing using pulled-in third party libraries.
