VaultPhrase is an offline security utility designed to generate ultra-secure, highly memorable passphrases using verified random wordlists (EFF Diceware).

Unlike standard passwords filled with hard-to-remember character strings, passphrases provide mathematically superior resistance against modern brute-force attacks while remaining easy for humans to recall and type.

🔑 Key Features:

100% Offline Security: Zero internet permissions required. Your passphrases are computed locally on your device using cryptographically secure random number generation (SecureRandom).

High-Entropy Passphrase Generation: Build custom passphrases using wordlists including EFF Long, EFF Short, Tech/Cybersecurity, and Simple English words.

Full Customization Control:

Adjust word count (3 to 10 words).

Select custom separators (hyphens, underscores, dots, or spaces).

Option to append random numbers or special symbols.

Auto-capitalization toggle for improved readability.

Real-Time Strength & Entropy Analyzer: Evaluate any passphrase or custom password with instant metrics:

Theoretical entropy score in bits.

Estimated offline brute-force crack time (@ 10 Billion guesses/sec).

Estimated online attack crack time (@ 1,000 requests/sec).

Actionable security recommendations to patch weak links.

Local History & Favorites: Log your generated passphrases locally, mark high-priority combinations as favorites, filter, search, or clear history anytime.

One-Tap Actions: Instantly copy passphrases to your clipboard or regenerate new ones in milliseconds.

Modern Material 3 Design: Includes native Dark and Light themes for seamless nighttime and daylight viewing.
