Password-Protected Notes

If you set a password during creation, users will need to enter it before accessing the content:

• Client-side verification: Password is checked on the user's device
• No server knowledge: ZeroNote never sees the password

🔒 Security Deep Dive

Understanding ZeroNote's security model helps you use the service more effectively:

Client-Side Encryption

// Simplified encryption process
async function encryptNote(content, password) {
    // 1. Generate random encryption key
    const encryptionKey = await crypto.getRandomValues(new Uint8Array(32));
    
    // 2. Derive key from password (if provided)
    const passwordKey = password ? 
        await deriveKeyFromPassword(password) : null;
    
    // 3. Encrypt content on client side
    const encryptedContent = await crypto.subtle.encrypt(
        { name: "AES-GCM", iv: randomIV },
        encryptionKey,
        new TextEncoder().encode(content)
    );
    
    // 4. Generate fragment key for sharing
    const fragmentKey = await generateFragmentKey(encryptionKey);
    
    return {
        encryptedContent,
        fragmentKey,
        // Password key never leaves client
        clientPasswordProtection: passwordKey !== null
    };
}
