Unique

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):

root@kali:~# john --wordlist=/usr/share/john/password.lst --rules unshadowed.txt
Warning: detected hash type "sha512crypt", but the string is also recognized as "crypt"

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.

Options:
 -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

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

-c		Show only complete auths (incomplete ones might be wrong passwords
		but we can crack what passwords were tried).
-v		Bump verbosity (can be used several times, try -vv)
-d		Do not suppress dupe hashes (per AP/STA pair)

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


zip2john
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.
