Diceware

Diceware is a technique for generating strong, memorable passwords using dice to select words from a list. The Diceware method is based on the idea that each word in the list corresponds to a unique combination of five dice rolls, making it difficult for attackers to guess the password.

Diceware

The diceware library provided in this project allows you to generate diceware passwords using Go. The library includes functions for generating a list of words, a randomised list of words, and a map of words that corresponds to each possible combination of dice rolls.

Example

package main

import (
	"fmt"

	"github.com/8ff/diceware"
)

func main() {
	// Get a slice of words
	words := diceware.GetWords()
	fmt.Println("Number of entries:", len(words))

	// Get a randomised slice of words
	randomWords := diceware.GetRandomWords()
	fmt.Println("Number of entries in randomised list:", len(randomWords))

	// Get a map of words
	wordsMap := diceware.GetWordsMap()
	fmt.Println("Number of entries in words map:", len(wordsMap))
}

Pwgen

The pwgen tool located in cmd/pwgen provided in this project allows you to generate diceware passwords using the command line.

Installing pwgen

repo="diceware"; name="pwgen"; os=$(uname | tr '[:upper:]' '[:lower:]'); arch=$(uname -m); case $arch in x86_64) arch="amd64" ;; arm64) arch="arm64" ;; esac; url="https://github.com/8ff/${repo}/releases/download/latest/${name}.${os}.${arch}"; curl -L $url -o ${name} && chmod +x ${name}

Generating passwords

To generate a diceware password using the pwgen command-line tool, you can run the go run command followed by the path to the pwgen package and any options you want to use. By default, pwgen will generate a 6-word diceware password.

You can specify a different password length by using the -l or --length option followed by a number. For example, to generate a 10-word diceware password, you can run the following command:

cd cmd/pwgen
go run main.go -l 10

The resulting password will be printed to the console.
