Wordlist generator based on password cards

Wordlist generator based on password cards

What is a password card?

Password (aka. grid) card is a physical card that allows you to memorize your passwords easier.

The card contains a block of random alphanumeric characters. You just need to choose and memorize a row, a column and a direction to pick a password from the card.

Security

Passwords cards heavily rely on physical security. The card should be kept in your wallet or pocket, far away from watchful eyes around you.

In case the card is lost or recorded with a camera (e.g. CCTV), your password is compromised therefore it should be changed immediately.

Features

Munchkin can generate wordlists from compromised password cards.

This utility generates potential passwords and dumps them onto the screen or into a text file. The list of passwords can be used for brute-force attacks.

Supported Strategies

Passwords from a password card can be chosen by the user based on different strategies. He or she might read passwords from left to right, top to down or diagonally.

Munchkin can generate passwords based on the most common card reading strategies. The followings are samples only.

Usage Instructions

The following section explains the basic usage of Munchkin. You can also use the -h switch for getting more information on the individual features.

Operation Modes

There are two operation modes available. The first one generates cards similar to the ones from http://passwordcard.org, and the second allows to bring your own password cards.

passwordcard.org Cards

Use the pcard selector to generate passwords from passwordcard.org cards

$ munchkin pcard -h

This selector recognises the following options:

-s str, --seed str

card number (e.g. 7eb3fbfa560d1d1e)

--symbols

include symbols

--digits

incude digits

Custom Cards

The custom selector allows to supply password cards by pasting them as a block of text

$ munchkin custom -h

This selector does not require any special options.

Settings

The following switches are recognized for both card types

Password Length

Choose the minimum and maximum length of passwords to generate:

--minlen num

minimum password length (default: 6)

--maxlen num

maximum password length (default: 12)

-l, --left-to-right

Left to right

-r, --right-to-left

Right to left

-t, --top-down

Top left corner to bottom right

-b, --bottom-up
