Password Generator & Vault

Core Features Explained

• Cryptographic Entropy: The code calculates password strength using the information theory formula $E = L \cdot \log_2(R)$, where $L$ is length and $R$ is the size of the character pool.

• True Randomness: Unlike Math.random(), which is pseudo-random and predictable, we use window.crypto.getRandomValues() for security-critical generation.

• Local Vault: Data is stored in the browser's localStorage. It remains there even if the page is refreshed, but never leaves your device.

• Clipboard Integration: Features a single-click copy for both the generated password and individual vault items.
