smartpasslib-js ^v4.0.0

• Zero-Storage Security — no passwords or secret phrases are ever stored or transmitted
• Decentralized Architecture — no central servers, no cloud dependency
• Cross-Platform Deterministic Generation — identical secret + parameters = identical password on any language
• Metadata Only — store only verification metadata (public keys, descriptions, lengths)
• On-Demand Regeneration — passwords are recalculated when needed
• Cryptographically Secure — uses Web Crypto API

• Decentralized & Serverless — no central database, no cloud lock-in
• Smart Password Generation — deterministic from secret phrase
• Public/Private Key System — 15-30 iterations for private key, 45-60 for public key
• Secret Verification — verify secret without exposing it
• Random Password Generation — cryptographically secure random passwords
• Authentication Codes — short codes for 2FA/MFA (4-100 chars)
• No Dependencies — pure JavaScript, uses Web Crypto API

• Proof of Knowledge — public keys verify secrets without exposing them
• Decentralized Trust — no third party needed
• Deterministic Security — same input = same output, always reproducible across platforms
• Dynamic Iteration Counts — private key: 15-30, public key: 45-60
• Zero Storage of Secrets — secret phrases exist only in your memory
• No Recovery Backdoors — lost secret = permanently lost passwords

Validation Rules: Secret phrase: min 12 chars · Password length: 12-100 chars · Code: 4-100 chars

Key derivation (same as Python/C#/Go/Kotlin versions v4.0.0):

Character Set:

!@#$%^&*()_+-=[]{};:,.<>?/ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz

Decentralized Architecture:

• No central authority required
• Metadata can be synced via any channel (USB, cloud, even paper)
• Your security depends only on your secret phrase
• Works offline — no internet connection required

Just copy smartpasslib.js to your project and include it:

<script src="path/to/smartpasslib.js"></script>

Generate Smart Password:

const secret = "MyStrongSecretPhrase2026!";
const length = 16;

const password = await SmartPassLib.generateSmartPassword(secret, length);
console.log(password);

Generate Public/Private Keys:

const secret = "MyStrongSecretPhrase2026!";

const publicKey = await SmartPassLib.generatePublicKey(secret);
const privateKey = await SmartPassLib.generatePrivateKey(secret);

console.log('Public Key (store locally):', publicKey);
console.log('Private Key (never store):', privateKey);

Verify Secret Against Public Key:

const secret = "MyStrongSecretPhrase2026!";
const storedPublicKey = "..."; // from local

const isValid = await SmartPassLib.verifySecret(secret, storedPublicKey);
if (isValid) {
    const password = await SmartPassLib.generateSmartPassword(secret, 16);
}

Generate Random Passwords:

// Strong random (cryptographically secure)
const strong = await SmartPassLib.generateStrongPassword(20);

// Base random
const base = await SmartPassLib.generateBasePassword(16);

// Authentication code (4-100 chars)
const code = await SmartPassLib.generateCode(8);

Input Validation:

Secret Phrase Requirements:

• Minimum 12 characters (enforced)
• Case-sensitive
• Use mix of: uppercase, lowercase, numbers, symbols
• Never store digitally
• NEVER use your password description as secret phrase

Strong Secret Examples:

✅ "MyStrongSecretPhrase2026!"   — mixed case + numbers + symbols
✅ "P@ssw0rd!LongSecret"         — special chars + numbers + length
✅ "GitHubPersonal2026!"         — description + extra chars

Weak Secret Examples (avoid):

❌ "short"                       — too short, raises exception
❌ "GitHub Account"              — using description as secret (weak!)
❌ "password"                    — dictionary word, too short
❌ "1234567890"                  — only digits, too short

Decentralized Nature:

There is no "forgot password" button. This is by design:

• No central server can reset your passwords
• No support team can recover your access
• Your secret phrase is the ONLY key

This is the price of true decentralization — you are completely in control.

• Pointer-Based Security Paradigm — 10.5281/zenodo.17204738
  Architectural Shift from Data Protection to Data Non-Existence
• Local Data Regeneration Paradigm — 10.5281/zenodo.17264327
  Ontological Shift from Data Transmission to Synchronous State Discovery
