root@kali:~# mailer
Usage: /usr/sbin/mailer PASSWORD-FILE


root@kali:~# unique
Usage: unique [-v] [-inp=fname] [-cut=len] [-mem=num] OUTPUT-FILE [-ex_file=FNAME2] [-ex_file_only=FNAME2]

       reads from stdin 'normally', but can be overridden by optional -inp=
       If -ex_file=XX is used, then data from file XX is also used to
       unique the data, but nothing is ever written to XX. Thus, any data in
       XX, will NOT output into OUTPUT-FILE (for making iterative dictionaries)
       -ex_file_only=XX assumes the file is 'unique', and only checks against XX
       -cut=len  Will trim each input lines to 'len' bytes long, prior to running
       the unique algorithm. The 'trimming' is done on any -ex_file[_only] file
       -mem=num.  A number that overrides the UNIQUE_HASH_LOG value from within
       params.h.  The default is 21.  This can be raised, up to 25 (memory usage
       doubles each number).  If you go TOO large, unique will swap and thrash and
       work VERY slow

       -v is for 'verbose' mode, outputs line counts during the run

john Usage Example

Using a wordlist (–wordlist=/usr/share/john/password.lst), apply mangling rules (–rules) and attempt to crack the password hashes in the given file (unshadowed.txt):

unique Usage Example

Using verbose mode (-v), read a list of passwords (-inp=allwords.txt) and save only unique words to a file (uniques.txt):

root@kali:~# unique -v -inp=allwords.txt uniques.txt
Total lines read 6089 Unique lines written 5083

John the Ripper is a tool designed to help systems administrators to find weak (easy to guess or crack through brute force) passwords, and even automatically mail users warning them about it, if it is desired.

Besides several crypt(3) password hash types most commonly found on various Unix flavors, supported out of the box are Kerberos AFS and Windows NT/2000/XP/2003 LM hashes, plus several more with contributed patches.

root@kali:~# base64conv -h
Created directory: /root/.john
base64conv: invalid option -- 'h'
Usage: base64conv [-l] [-i intype] [-o outtype] [-q] [-w] [-e] [-f flag] [data[data ...] | < stdin]
 - data must match input_type i.e. if hex, then data should be in hex
 - if data is not present, then base64conv will read data from std input)
 - if data read from stdin, max size of any line is 256k

  -q will only output resultant string. No extra junk text
  -e turns on buffer overwrite error checking logic
  -l performs a 'length' test

  -r ifname  process whole file ifname (this is the input file)
  -w ofname  The output filename for whole file processing
             NOTE, -r and -w have to be used as a pair

Input/Output types:
  raw      raw data byte
  hex      hexadecimal string (for input, case does not matter)
  mime     base64 mime encoding
  crypt    base64 crypt character set encoding
  cryptBS  base64 crypt encoding, byte swapped

Flags (note more than 1 -f command switch can be given at one time):
  HEX_UPCASE         output or length UPCASED (input case auto handled)
  HEX_LOCASE         output or length locased (input case auto handled)
  MIME_TRAIL_EQ      output mime adds = chars (input = auto handled)
  CRYPT_TRAIL_DOTS   output crypt adds . chars (input . auto handled)
  MIME_PLUS_TO_DOT   mime converts + to . (passlib encoding)
  MIME_DASH_UNDER    mime convert +/ into -_ (passlib encoding)

root@kali:~# bitlocker2john -h

root@kali:~# cprepair -h
Codepage repair (c) magnum 2014-2019

Input can be a mix of codepages, UTF-8 and double-encoded UTF-8, and with
a mix of Windows (CRLF) and Unix (LF) line endings, or missing line endings
on last lines.  If no file name is given, STDIN is used.
Output is UTF-8 with LF line endings and no silly BOM.

Usage: cprepair [options] [file(s)]
 -i <cp>   Codepage to assume for 8-bit input. Default is CP1252 (MS Latin-1)
 -f <cp>   Alternate codepage when no ASCII letters (a-z, A-Z) seen (default
           is to not treat them differently)
 -n        Do not guess (leave 8-bit as-is)
 -s        Suppress lines that does not need fixing.
 -d        Debug (show conversions).
 -l        List supported encodings.
 -p        Only convert stuff after first ':' (.pot file).
 -P        Suppress output lines with unprintable ASCII and, when used together
           with -n option, also suppress lines with invalid UTF-8

Converts PCAP or IVS2 files to JtR format.

Usage: wpapcap2john [options] <file[s]>

-c		Show only complete auths (incomplete ones might be wrong passwords

-v		Bump verbosity (can be used several times, try -vv)
-d		Do not suppress dupe hashes (per AP/STA pair)
-r		Ignore replay-count (may output fuzzed-anonce handshakes)
-f <n>		Force anonce fuzzing with +/- <n>
-e <essid:mac>	Manually add Name:MAC pair(s) in case the file lacks beacons.

-m <mac>	Ignore any packets not involving this mac address

root@kali:~# zip2john -h
zip2john: invalid option -- 'h'
Usage: zip2john [options] [zip file(s)]
 -s Scan archive from the beginning, looking for local file headers. This
    is less reliable than going by the central index, but might work better
    with corrupted or split archives.
Options for 'old' PKZIP encrypted files only:
 -a <filename>   This is a 'known' ASCII file. This can be faster, IF all
    files are larger, and you KNOW that at least one of them starts out as
    'pure' ASCII data.
 -o <filename>   Only use this file from the .zip file.
 -c This will create a 'checksum only' hash.  If there are many encrypted
    files in the .zip file, then this may be an option, and there will be
    enough data that false positives will not be seen.  Up to 8 files are
    supported. These hashes do not reveal actual file data.
 -m Use "file magic" as known-plain if applicable. This can be faster but
    not 100% safe in all situations.

NOTE: By default it is assumed that all files in each archive have the same
password. If that's not the case, the produced hash may be uncrackable.
To avoid this, use -o option to pick a file at a time.
