# What

Remove duplicate Hashcat rules.

# How does it works ?

TL;DR: Each rule change is mapped, and a unique id is generated for each rule with functions count.

The mechanism is like this:

- A blank map is created with N ( from 1 to 36 ) slots.

- Each rule change will be applied to the map.

    Example rule: 'u', will change all characters cases from '?' ( unknown ) to 'u' ( upper case ).

    'sab', will add {'a' -> 'b'} to the map. And same logic apply for the other rules.

- An id is generated from the map.

- The ids are compared to detect duplicate rules.

- The rule with the least functions count will be selected.

# Which rules are supported ?

All rules on [this page](https://hashcat.net/wiki/doku.php?id=rule_based_attack) are supported except:

    - Memory rules: X, 4, 6, M

    - Reject plains rules

    - L, R, +, -

    - E, e

# Usage

```

Remove duplicate Hashcat rules.

Usage:

    duprule [options] < input

Reads input from STDIN and prints to STDOUT.

Options:

    -o, --output      optional	 file to write duplicate rules to

    -v, --version     optional	 print version info

    -h, --help        optional	 print this help message

    -s, --supported   optional	 list all supported rules

Examples:

duprule < rockyou.rule > rockyou.rule.uniq

duprule -o duplicates.txt < rockyou.rule > rockyou.rule.uniq

```
