Passphrase-Generator

My attempt at making security a little less... forgettable. This script generates passphrases using two distinct patterns (Adjective-Noun-Symbol-Number and Verb-Adverb-Symbol-Number) by creatively combining words and symbols. Give it a whirl and boost your memory (and maybe your security!).

This Python script provides a simple and fun way to generate memorable passphrases using two distinct patterns: Adjective-Noun-Symbol-Number (ajn) and Verb-Adverb-Symbol-Number (vas). Instead of relying on complex and easily forgotten character combinations, this script leverages the power of familiar words combined with symbols and numbers, making the generated passphrases easier to recall.

Features

• Two Passphrase Patterns:
  • Adjective-Noun-Symbol-Number (ajn): Creates passphrases by randomly selecting an adjective, a noun, a symbol, and a number, and joining them with hyphens (e.g., vibrant-sunset-$-42). This pattern leverages descriptive language to aid memory.
  • Verb-Adverb-Symbol-Number (vas): Generates passphrases by randomly picking a verb, an adverb, a symbol, and a number, connected by hyphens (e.g., quickly-jumps-@-19). This pattern uses action-oriented language for better recall.
• File-Based Word Lists: The script loads words for each part of the patterns from separate text files (adjectives.txt, nouns.txt, verbs.txt, adverbs.txt, symbols.txt, numbers.txt). This allows for easy customization and expansion of the word and symbol pools. Each word in the text file should be on a new line.
• Error Handling: The script includes basic error handling to check if the required word list files are found. If a file is missing, it prints an informative error message and returns an empty list for that word category, preventing the passphrase generation from crashing.
• User-Friendly Interface: Upon execution, the script prompts the user to choose between the two passphrase patterns (ajn or vas). Based on the user's input, it generates and displays a memorable passphrase following the selected pattern. It also provides feedback for invalid choices.
• Random Selection: The random module is used to ensure that each generated passphrase is unique and unpredictable by randomly selecting words and symbols from the loaded lists.

How to Use

1. Clone the repository (or download the Python script).
2. Create the necessary text files:
   • adjectives.txt: Contains a list of adjectives, one per line.
   • nouns.txt: Contains a list of nouns, one per line.
   • verbs.txt: Contains a list of verbs, one per line.
   • adverbs.txt: Contains a list of adverbs, one per line.
   • symbols.txt: Contains a list of symbols (e.g., @, #, $, %, &, *), one per line.
   • numbers.txt: Contains a list of numbers (you can have single digits or multi-digit numbers), one per line.
3. Populate the text files with your desired words, symbols, and numbers. The more diverse your lists, the more varied your generated passphrases will be.
4. Run the Python script:

   python your_script_name.py

5. Follow the prompts: The script will ask you to choose a passphrase pattern (ajn or vas). Enter your choice and press Enter.
6. Your memorable passphrase will be displayed on the console.

Customization

• Word Lists: You can easily customize the generated passphrases by editing the content of the text files. Add more words, different symbols, or a wider range of numbers to suit your preferences.
• File Paths: If you want to use different filenames for your word lists, you can modify the default filepath arguments in the load_words function and the adj_file, noun_file, verb_file, adverb_file, symbol_file, and num_file arguments in the generate_patterned_phrase_ajn and generate_patterned_phrase_vas functions.

Potential Enhancements

• More Passphrase Patterns: Adding more creative patterns (e.g., Adverb-Verb-Noun-Number, etc.).
• Word Filtering: Implementing options to filter words based on length or other criteria.
• GUI Interface: Creating a graphical user interface for easier interaction.
• Saving Passphrases: Adding functionality to save generated passphrases securely.
• Pronounceable Passphrases: Exploring techniques to generate passphrases that are easier to pronounce.

This script aims to strike a balance between security and memorability, offering a more human-friendly approach to password generation.
