Installation

npm install @hixbe/sig

Quick Start

Basic Usage

import { generateId } from '@hixbe/sig';

// Simple random ID
const id = await generateId();
console.log(id); // e.g., "xK7mP9nQ2vL8wR4tY6uI3oE5aS1dF0gH"

// With custom length
const shortId = await generateId({ length: 16 });
console.log(shortId); // e.g., "mK7P9n2vL8wR4tY6"

// Custom separator segments
const formattedId = await generateId({ 
  length: 24, 
  separator: '-', 
  separatorLength: 3 
});
console.log(formattedId); // e.g., "mK7-P9n-2vL-8wR-4tY-6uI-3oE-5aS"

Checksum Length Control

// Default: 1-character checksum (compact)
const compactId = await generateId({
  length: 20,
  prefix: 'TRX',
  separator: '-',
  checksum: true,
  checksumLength: 1,  // Default
});
console.log(compactId); // e.g., "TRX-KMTQ61DF-RLK2AGNX-4"

// 4-character checksum (balanced)
const balancedId = await generateId({
  length: 20,
  prefix: 'PAY',
  separator: '-',
  checksum: true,
  checksumLength: 4,
});
console.log(balancedId); // e.g., "PAY-6UL0A28B-IBPWQ49Q-3C7E"

// 8-character checksum (maximum security)
const secureId = await generateId({
  length: 20,
  prefix: 'ORD',
  separator: '-',
  checksum: true,
  checksumLength: 8,
});
console.log(secureId); // e.g., "ORD-KYQCZAOA-6SMRIDES-A418F0EB"

Recommended Configuration for Maximum Security:

// For payment IDs, API keys, or high-security operations:
const id = await generateId({
  length: 32,
  mode: 'hmac-hash',              // Maximum security mode
  algorithm: 'sha3-512',          // Quantum-resistant
  secret: process.env.SECRET_KEY, // HMAC signing key
  salt: generateRandomSalt(),     // Per-ID randomness
  pepper: process.env.PEPPER,     // Global secret (never in DB)
  checksum: true,
  checksumCount: 2,
  security: {
    enhanceEntropy: true,
    timestampEmbed: true,
    avoidAmbiguousChars: true,
    collisionDetection: true,
    auditLog: true,
  },
});

Security Best Practices

1. Store secrets externally: Use environment variables or secret management systems (AWS Secrets Manager, HashiCorp Vault)
2. Use quantum-resilient algorithms: Prefer SHA3, BLAKE2b, or SHAKE256 for future-proofing
3. Enable checksums: For critical IDs that need integrity verification
4. Use HMAC modes: When IDs need to be tamper-proof (payments, API keys)
5. Embed timestamps: To prevent replay attacks
6. Memory-hard mode: For high-value IDs (slower but more secure)
7. Always use random salts: Generate unique salt per ID with generateRandomSalt()
8. Separate pepper storage: Store pepper in environment, NEVER in database
9. Enable collision detection: For uniqueness guarantees in high-volume systems
10. Implement rate limiting: Prevent brute-force attempts at application level

Security Notice

⚠️ CRITICAL: User Responsibility

This package provides cryptographic tools for secure ID generation. Security depends entirely on proper configuration:

Your Responsibilities:

1. Secret Management: NEVER hardcode secrets in your application

   // ❌ WRONG - Secret in code
   const id = await generateId({ secret: 'my-secret-123' });
      
   // ✅ CORRECT - Secret from environment
   const id = await generateId({ secret: process.env.SECRET_KEY });

2. Key Storage: Store keys in:

   • ✅ Environment variables
   • ✅ Secret management systems (AWS Secrets Manager, HashiCorp Vault, Azure Key Vault)
   • ✅ Hardware Security Modules (HSM)
   • ❌ NEVER in database
   • ❌ NEVER in source code
   • ❌ NEVER in version control

3. Pepper Separation: Store pepper separately from your database

   • If database is breached, pepper remains secure
   • This is defense-in-depth security

4. Security Audits: For payment systems and critical applications:

   • Conduct regular security audits
   • Perform penetration testing
   • Review key rotation procedures
   • Monitor for anomalies

Disclaimer:

This software is provided "as is" without warranty. While we use industry-standard cryptographic practices, you are responsible for:

• Proper configuration and key management
• Security audits for your specific use case
• Compliance with regulations (PCI-DSS, HIPAA, etc.)
• Incident response and monitoring

For payment gateways and high-security applications, we recommend:

• Professional security audit before production deployment
• Compliance verification with your industry standards
• Regular security updates and monitoring

Responsible Disclosure:

Found a security vulnerability? Please report it responsibly:

1. Do NOT open a public GitHub issue
2. Email security concerns to: [email protected]
3. Allow reasonable time for fix before public disclosure

Performance

• Random mode: ~500,000 IDs/sec
• Hash mode: ~200,000 IDs/sec
• HMAC mode: ~150,000 IDs/sec
• Memory-hard mode: ~100 IDs/sec (intentionally slow)
