Hash & Encoding Utilities

A comprehensive suite of hashing, UUID, encoding, and lightweight cryptographic utilities—including JWT-style signing Signet, stream-cipher encryption Cipher, and more.

info

Does not rely on Node.js or Web APIs. Works on any JS engine

Available Utilities​

Hash Functions​

  • md5 - Compute MD5 hash (32-character hex)
  • sha1 - Compute SHA-1 hash (40-character hex)
  • sha256 - Compute SHA-256 hash (64-character hex)

UUID Utilities​

  • uuid - Generate RFC-compliant UUIDs (versions 1, 3, 4, 5, 6, 7, 8)
  • decodeUUID - Decode UUIDs into version, variant, and timestamp information
  • Version Checkers - Type-safe (branded type) validation for specific UUID versions

Encryption/Authentication Tools​

  • Signet - Sign, decode, verify tokens in JWT style
  • Cipher - Encrypt, decrypt text in stream-cipher encryption style

Other Utilities​

Quick Start​

import { uuid, md5, randomHex } from 'nhb-toolbox/hash';

// Generate a random UUID v4
const id = uuid();

// Create MD5 hash
const hash = md5('hello world');

// Generate random token
const token = randomHex(16, true);

Features​

  • Cross-platform - Works in Node.js, browsers, and edge runtimes
  • Type-safe - Full TypeScript support with branded types
  • RFC compliant - Follows UUID and hash specifications
  • No dependencies - Pure JavaScript implementation

Common Use Cases​

  • Generating unique identifiers
  • Data integrity verification
  • Creating random tokens and nonces
  • Cryptographic hashing needs
  • Encrypting/decrypting text, tokens etc.
