A: If you're using the '--format' option, try dropping it. Except for
the special case mentioned in the answer above, '--format' is normally a
way to choose one of multiple hash/cipher types found in the same file
or to clarify the hash/cipher type if it would otherwise be ambiguous
(e.g., a 32 hexadecimal character string may correspond to one of many
distinct hash types). That is, you normally only need to use '--format'
when John would otherwise misdetect your hash/cipher type (e.g., when it
says LM and you know that your hashes are in fact raw MD5, you'd use
'--format=raw-md5' with -jumbo) or if it would load undesired entries
from the file. If John does not load anything, then your use of
'--format' is probably unreasonable (or you should be using a different
version/build of John - see the answer below).
A: Your password hash or cipher type(s) might not be supported by John,
or at least by the version and build of John that you're using. If
you're using a non-jumbo version, you will likely want to try -jumbo
instead, which supports a lot of additional hash and cipher types (e.g.,
you currently need -jumbo for raw MD5). If unsuccessful with that and
if other answers (above and below this one) don't apply, please post a
note to the mailing list (see CONTACT) including a sample password file
line that John does not load (please make sure that the password is
already changed by the time you post).
A: John only loads properly formatted text files directly. It can load
/etc/passwd and PWDUMP format files. Starting with version 1.7.6, it
can also load text files containing one password hash per line (and
nothing else on that line). Some other file formats are supported via
extra tools (supplied with John): unafs (Kerberos AFS database files),
undrop (Eggdrop IRC bot userfiles), ssh2john (OpenSSH private keys),
pdf2john (some password-protected PDF files), rar2john (some
password-protected RAR archives), zip2john (some password-protected
PKZIP and WinZip archives). You need -jumbo for most of these. To use
the proper one of these (for your file format), run it on your file(s)
and redirect the output to a new file (using your shell's output
redirection feature - e.g., './ssh2john ~/.ssh/id_rsa > sshpasswd').
Then run John on the resulting file (e.g., './john sshpasswd').

(because they could in fact be LM, as well as for compatibility with
non-jumbo), but it suggests that you use '--format=raw-md5', which is
what you should in fact use in this case. It makes other suggestions as
well because it does not know whether your hashes are raw MD5 or
something else. You're supposed to know this and choose the right one
of the suggested '--format=...' options. If you're not getting a
suggestion like this from John 1.7.7 or newer even though you're not yet
using the '--format' option, this means that your version and build of
John does not recognize the encodings as ambiguous, which may mean that
it does not support the actual hash or cipher type that you have in
mind. If you're already using the '--format' option, try dropping the
option to receive the suggestions. If you're using a non-jumbo version
of John, the first step is for you to try -jumbo instead. As of this
writing, you do need -jumbo for some popular hash types such as raw MD5
and NTLM.
Q: What do the various numbers printed on the status line mean?
A: As of version 1.8.0, the status line may include: successful guess
count ('g'), session duration (in the D:HH:MM:SS format for days, hours,
minutes, and seconds), progress indicator (percent done and optionally
pass number out of the total number of passes), up to four speed metrics
('g/s', 'p/s', 'c/s', and 'C/s'), and the current (range of) candidate
password(s) being tested (John is often able to test multiple candidate
passwords in parallel for better performance, hence a range). The four
speed metrics are as follows: g/s is successful guesses per second (so
it'll stay at 0 until at least one password is cracked), p/s is
candidate passwords tested per second, c/s is 'crypts' (password hash or
cipher computations) per second, and C/s is combinations of candidate
password and target hash per second. Versions of John prior to 1.8.0
displayed only the C/s rate (calling it c/s). When you restore a
pre-1.8.0 session with version 1.8.0 or newer, only the g/s and C/s
rates will be displayed, because the older .rec file format lacked
information needed to compute p/s and c/s.
Q: I am running John for 10 days and it is still not finished?!
Q: How long should I expect John to run?
A: It primarily depends on the cracking mode(s) and on your password
files (in particular, the type of hashes and the number of different
salts, if applicable). Most importantly, you should note that the
'incremental' mode, which a default John run (with no command line
options) proceeds with after being done with the quicker checks, is not
supposed to terminate in a reasonable time. It is up to you to decide
how long you're going to let it run, then consider any uncracked
passwords strong enough. 'Single crack' mode runs typically take from
under a second to one day (depending on the type and number of password
hashes). Wordlist mode runs may also be quick (under a second) for
tiny wordlists and fast hashes or they may take multiple days with large
wordlists, with word mangling rules, and with slow hash types and
substantial numbers of different salts. The status line John reports
whenever you hit a key includes a progress indicator (percent complete)
for 'single crack' and wordlist modes. With no cracking mode requested
explicitly, John will start with 'single crack' mode (pass 1), then
proceed with wordlist mode (pass 2), and finally with 'incremental' mode
(pass 3). The pass numbers are reported on the status line, too. It is
reasonable to let John reach 'incremental' mode (pass 3) and run that
for a while (some days). You will notice that John's success rate (the
number of passwords cracked per hour or per day) will be dropping
rapidly. When you determine that the success rate is low enough, you
interrupt John.
Q: Does John support multi-processing or distributed processing?
A: Yes, but you need to explicitly enable this if desired. Starting
with version 1.8.0, there's the '--fork' option on Unix-like systems (to
make use of multiple CPUs and/or CPU cores in a single system) and the
'--node' option on all systems (this one allows for a trivial form of
distributed processing). The '--fork' and '--node' options may also be
used together. Please refer to OPTIONS for a description of these
options. Additionally, there's built-in parallel processing support
using OpenMP for all crypt(3) hash flavors (DES-, MD5-, and
Blowfish-based) supported by John natively, and when running on Linux or
Solaris also for the underlying system's thread-safe password hashing
function. The latter is only reasonable to use for crypt(3) hash types
not yet supported by John natively (such as for glibc 2.7+ SHA-crypt
hashes as used by recent versions of Fedora and Ubuntu, and for SunMD5
hashes, which may optionally be enabled on Solaris). In 'community
enhanced' -jumbo versions, parallelization with OpenMP is also supported
for many (but not all) of the hash and cipher types added in those
versions (including for their built-in implementation of SHA-crypt).
To use John's OpenMP support, you need to either use an existing
OpenMP-enabled build (e.g., 'john-omp.exe' on Windows) or make an
OpenMP-enabled build by uncommenting one of the OMPFLAGS lines near the
beginning of Makefile. This requires GCC 4.2 or newer, or another
OpenMP-capable C compiler. For other hash or cipher types and/or to
distribute the workload between multiple machines, other approaches need
to be used. One of those approaches is to use the '--fork' and '--node'
options. For a very small number of nodes (CPUs, CPU cores, and/or
machines), it is also reasonable to use a manual approach, such as to
have your nodes try different password lengths. This is easily
accomplished with 'incremental' mode's 'MinLen' and 'MaxLen' settings
(see CONFIG). You might not need to split the workload for 'single
crack' and wordlist modes since these are typically relatively quick,
although '--fork' and '--node' are supported for these modes too. You
may safely run multiple instances of John in the same working directory,
all writing to the same 'pot file' (this is a feature). You do,
however, need to assign each of them a unique session name, with
'--session' (please note that doing so does not eliminate the need to
also distribute the workload with '--node' or otherwise, as discussed
above). Other approaches, such as splitting password files naively
(without regard to salts), are typically less efficient (in some cases
to the extent where there's no speedup from using multiple nodes at
all). Some other approaches, such as using MPI, are listed on the wiki

'incremental' mode, which a default John run (with no command line

supposed to terminate in a reasonable time. It is up to you to decide
how long you're going to let it run, then consider any uncracked

for a while (some days). You will notice that John's success rate (the
number of passwords cracked per hour or per day) will be dropping
rapidly. When you determine that the success rate is low enough, you
interrupt John.
Q: Why does John display meaningless c/s values while cracking, instead
of real 'crypts per second' rate?
A: The values displayed by John mean combinations (of username and
password) per second, not crypts per second. This is the effective
cracking speed that you get on a particular set of password hashes, and
it may be useful, for example, to tune the '--salts=...' threshold and
other settings. If you want a benchmark of the low-level password
hashing routines only, use '--test'. (Future versions of John the
Ripper might report effective and raw c/s rates for different time
intervals. These won't fit on the current status line, though.)
Q: I just noticed that the c/s rate reported while using 'incremental'

(to make use of multiple CPUs and/or CPU cores in a single system) for
all crypt(3) hash flavors (DES-, MD5-, and Blowfish-based) supported by
John natively, as well as for LM hashes and, when running on Linux or

Practice ntds.dit File Part 6: Password Cracking With John the Ripper – Wordlist

After password cracking examples with hashcat, I want to show you how to crack passwords with John the Ripper (remember we also produced hashes for John the Ripper: lm.john.out and nt.john.out).

First we use the rockyou wordlist to crack the LM hashes:
