About This Tool

Essential backend cryptographic and token utility powered by the Web Crypto API.

Cryptographic hash generation (SHA-256, SHA-512, MD5), HMAC webhook signing, UUID v4, and Unix epoch converter.

1How to Use

  1. 1Select 'Hash & HMAC' to compute digests using SHA-256, SHA-512, SHA-384, SHA-1, or MD5 in Hex and Base64.
  2. 2Optionally provide a secret key to compute HMAC signatures for Stripe, GitHub, or Shopify webhooks.
  3. 3Switch to 'UUID & Keys' to batch generate cryptographically random UUID v4s and secure hex API keys.
  4. 4Switch to 'Unix Timestamp' to convert between epoch timestamps and human-readable UTC/local dates.

2Key Features

  • ✓High-performance native hashing via Web Crypto API with optional HMAC secret signing
  • ✓Batch UUID v4 generator with custom uppercase and no-hyphen formatting options
  • ✓Cryptographically secure random secret and API key generator (128-bit to 512-bit entropy)
  • ✓Live ticking Unix Epoch clock and bidirectional Timestamp <-> Date converter

Client-Side Privacy Guarantee

All hashes and tokens are calculated locally using the browser's hardware-accelerated Web Crypto API. SHOFIDEV_TOOLS does not transmit, store, or log any of your files, text, or tokens on external servers.
