HMAX-SECURE 🔒

Enterprise-Grade Military-Level Password Hashing System

A comprehensive, bank-grade password hashing library implementing modern cryptographic best practices with HMAC, secret rotation, pepper support, and multiple KDF layers.

🚀 Features

• Multi-Layer Security: HMAC-SHA512 + Secret + Pepper + KDF (Argon2id/PBKDF2)
• Secret Rotation: Automatic key rotation without password re-entry
• Timing-Safe Verification
• Versioned Output
• NIST/FIPS compliant configurations
• Zero Dependencies
• TypeScript Ready

📦 Installation

npm install hmax-secure

🛠 Quick Start

Basic Usage

import hmax from 'hmax-secure';

await hmax.initialize({
  currentSecret: hmax.generateSecret()
});

const hash = await hmax.createHash('mySecurePassword');
console.log(hash);

const result = await hmax.verifyPassword('mySecurePassword', hash);
console.log(result.verified);

⚙️ Advanced Configuration

import hmax, { config } from 'hmax-secure';

config.setConfig({
  argon2: {
    memoryCost: 131072,
    timeCost: 4,
    parallelism: 2
  },
  secrets: {
    enablePepper: true,
    enableRotation: true,
    maxPreviousSecrets: 5
  }
});

await hmax.initialize({
  currentSecret: masterSecret,
  previousSecrets: [oldSecret1, oldSecret2]
});

const pepper = hmax.generatePepper();
const hash = await hmax.createHash('password', { pepper });

🔧 API Reference

Core Methods

• createHash(password, options?)
• verifyPassword(password, hash, pepper?)
• extractMetadata(hash)
• migrateHashIfOutdated(password, hash, pepper?)
• generateSecret(length?)
• generatePepper(length?)
• rotateSecret(newSecret?)

Config

• config.getConfig()
• config.setConfig(newConfig)

🛡 Security Features

Multi-Layer Crypto Stack

• HMAC-SHA512 sealing
• Per-password 32-byte random salt
• Optional pepper
• KDF layer (Argon2id or PBKDF2)
• Timing-safe comparison
• Versioned hash format

🔄 Secret Rotation Example

const newSecretId = hmax.rotateSecret();

const result = await hmax.verifyPassword('password', oldHash);

const migration = await hmax.migrateHashIfOutdated('password', oldHash);
if (migration.migrated) {
  // Save migration.newHash
}

🧬 Hash Format

hmax$<version>$<algorithm>$<salt>$<params>$<hash>

Examples:

hmax$2$argon2id$uTSYylWT...$3$65536$4$8A3B...
hmax$1$pbkdf2$kf8XylWT...$210000$kf8XylWT...

🔒 Security Recommendations

• Use 64+ byte master secrets
• Store secrets away from hashes
• Rotate every quarter
• Peppers: 32+ bytes
• Argon2id recommended
• Aim for 500ms–1s compute time

📋 Migration Strategy

const legacyVerified = verifyWithLegacySystem(password, legacyHash);
if (legacyVerified) {
  const newHash = await hmax.createHash(password);
}

Check version:

const metadata = hmax.extractMetadata(existingHash);

🖥 CLI Tool

npm install -g hmax-secure

hmax hash "myPassword"
hmax verify "myPassword" "hmax$2$argon2id$..."
hmax gen-secret
hmax gen-pepper
hmax inspect "hmax$2$argon2id$..."

⚠️ Security Warnings

• Never store secrets with hashes
• Use secure RNG
• Protect peppers
• Apply proper key rotation
• Always use HTTPS/TLS

🏢 Enterprise Usage

Banking

• HSM for secret storage
• Quarterly key rotation
• Dedicated peppers per microservice

Military/Government

• Multi-factor secret custody
• Extreme Argon2 parameters
• Regular penetration testing

🔍 Testing & Auditing

const audit = hmax.auditHash(storedHash);
console.log(audit.secure);
console.log(audit.issues);
