DicewarePy

A simple and secure passphrase generator based on the Diceware™ method created by Arnold G. Reinhold.

🎲 What is Diceware?

Diceware is a method for creating passphrases, passwords, and other cryptographic variables using an ordinary dice as a source of randomness. This method ensures that your passphrases are truly random and secure against various types of attacks.

✨ Features

• 🌍 Multi-language support: English and Spanish wordlists included
• 🎯 True randomness: Uses secure random number generation
• 📝 7,776 words per language: Complete standard Diceware wordlists
• 🖥️ Simple CLI interface: Easy-to-use command-line interface
• 🔒 Secure: No internet connection required, runs completely offline

🚀 Quick Start

Prerequisites

• Python 3.6 or higher

Installation

1. Clone this repository:

git clone https://github.com/th-hoffmann/DicewarePy.git
cd DicewarePy

2. Run the script:

python3 Diceware.py

Usage

1. Run the program:

   python3 Diceware.py

2. Select your language:

   • 1 for English
   • 2 for Español (Spanish)
   • 0 to Exit

3. Choose the number of words for your passphrase (recommended: 6-8 words)

4. Your secure passphrase will be generated!

📖 Example

$ python3 Diceware.py

                        Diceware Passphrase Generator

    1. English
    2. Español
    0. Exit

Select the language: 1
Enter the number of words for your password: 6

51234 -> horse
41356 -> battery
23145 -> staple
61432 -> correct
15234 -> amount
34512 -> system

🔐 Security Considerations

• Use 6-8 words for strong security (recommended by security experts)
• Each additional word exponentially increases security
• Don't reuse passphrases across different accounts
• Store securely using a password manager when possible

Passphrase Strength

Words	Possible Combinations	Equivalent Random Password
4	~3.6 × 10¹⁵	~51 bits
5	~2.8 × 10¹⁹	~64 bits
6	~2.2 × 10²³	~77 bits
7	~1.7 × 10²⁷	~90 bits
8	~1.3 × 10³¹	~103 bits
