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

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

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 });

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
Pepper Separation: Store pepper separately from your database
- If database is breached, pepper remains secure
- This is defense-in-depth security
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:

Do NOT open a public GitHub issue
Email security concerns to: security@hixbe.com
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)
