XPhrase Project: Innovation Completed and Available! 🐍 XPhrase is ready to use! A powerful Python tool that generates words intelligently, safely, and versatilely!
📢 Check it out now! XPhrase💥
XPhrase Generation is a multilingual phrase generator designed for command-line interface (CLI) usage. It creates expressive, randomized phrases using words from 🇬🇧 English, 🇩🇪 German, and 🇧🇷 Portuguese, interlinked with special characters and digits.
Cryptographic-strength randomization via CSPRNG, achieved through the combination of words in different languages, special characters, and digits. This construction significantly increases the entropy of the phrase, making it unfeasible to break using traditional brute-force methods, even in shorter phrases.
Key Features:
- ✨ Interactive Network Configuration: Configurable hidden layers (1-5).
- 🔢 At least one special character: !@#$%^&*()_+-=[]{}|;:,.<>?~\.
- 🔢 At least one digit character: 0123456789.
- 💯 Written 100% in Python: Generates phrases with 3 to 21 words.
