NAME

fcrackzip - a Free/Fast Zip Password Cracker  

SYNOPSIS

fcrackzip [-bDBchVvplum2] [--brute-force] [--dictionary] [--benchmark] [--charset characterset] [--help] [--validate] [--verbose] [--init-password string/path] [--length min-max] [--use-unzip] [--method name] [--modulo r/m] file...  

DESCRIPTION

fcrackzip searches each zipfile given for encrypted files and tries to guess the password. All files must be encrypted with the same password, the more files you provide, the better.  

OPTIONS

-h, --help
Prints the version number and (hopefully) some helpful insights.
-v, --verbose
Each -v makes the program more verbose.
-b, --brute-force
Select brute force mode. This tries all possible combinations of the letters you specify.
-D, --dictionary
Select dictionary mode. In this mode, fcrackzip will read passwords from a file, which must contain one password per line and should be alphabetically sorted (e.g. using (1)).
-c, --charset characterset-specification
Select the characters to use in brute-force cracking. Must be one of

  a   include all lowercase characters [a-z]
  A   include all uppercase characters [A-Z]
  1   include the digits [0-9]
  !   include [!:$%&/()=?[]+*~#]
  :   the following characters upto the end of the spe-
      cification string are included in the character set.
      This way you can include any character except binary
      null (at least under unix).

For example, a1:$% selects lowercase characters, digits and the dollar and percent signs.

-p, --init-password string
Set initial (starting) password for brute-force searching to string, or use the file with the name string to supply passwords for dictionary searching.
-l, --length min[-max]
Use an initial password of length min, and check all passwords upto passwords of length max (including). You can omit the max parameter.
-u, --use-unzip
Try to decompress the first file by calling unzip with the guessed password. This weeds out false positives when not enough files have been given.
-m, --method name
Use method number "name" instead of the default cracking method. The switch --help will print a list of available methods. Use --benchmark to see which method does perform best on your machine. The name can also be the number of the method to use.
-2, --modulo r/m
Calculate only r/m of the password. Not yet supported.
-B, --benchmark
Make a small benchmark, the output is nearly meaningless.
-V, --validate
Make some basic checks wether the cracker works.
