Passphrase Generator Features

MVP (Minimum Viable Product)

• Generate passphrases using wordlists (English and Spanish)
• Accept arguments for language, word length, and vowel replacement
• Meet minimum and maximum length requirements (12-128 characters, 2-15 words)
• Randomly swap cases (uppercase) at least half of the letters on each word
• Handle errors and exceptions

Phase 1 (Easy-Moderate)

• Implement a feature to generate passphrases with a specific theme (e.g., animals, countries, foods)
• Allow users to specify a custom wordlist file
• Add a feature to generate passphrases with a specific number of syllables
• Improve performance by optimizing wordlist loading and passphrase generation
• Allow users to add a custom word to their passphrase
• Implement -help argument to display usage information

Phase 2 (Moderate-Hard)

• Implement a feature to generate passphrases with a specific pattern (e.g., alternating uppercase and lowercase letters)
• Add support for generating passphrases with a specific character set (e.g., only alphanumeric characters)
• Implement a feature to generate passphrases with a specific entropy level (e.g., using a password strength estimator)
• Allow users to specify a custom character set for vowel replacement
• Improve error handling and exception handling

Phase 3 (Hard)

• Implement a feature to generate passphrases with a specific linguistic structure:

  • Define what constitutes a linguistic structure (e.g., noun-verb-noun).
  • Create a set of rules for generating passphrases based on these structures.
  • Implement a mechanism to select words that fit the defined structure.

• Implement a feature to generate passphrases with a specific semantic meaning:

  • Research and define what types of semantic meanings can be used (e.g., themes like "adventure" or "safety").
  • Create a mapping of words to their semantic categories.
  • Develop a method to generate passphrases that align with the chosen semantic meaning.

Future Features (Graphic User Interface)

• Implement a graphic user interface (GUI) for the passphrase generator
• Allow users to interact with the passphrase generator using a GUI
• Implement features such as passphrase history, favorites, and password analysis

Future Features (Web-Based Version)

• Implement a web-based version of the passphrase generator
• Allow users to access the passphrase generator through a web interface
• Include features such as:
  • User authentication to save favorite passphrases
  • A history of generated passphrases for easy access
  • Responsive design for mobile and desktop users
