About Hash Generator

The KoolToolz Hash Generator produces cryptographic message digests and keyed-hash message authentication codes (HMAC) entirely in your browser using the standard Web Cryptography API. Your input text and secret keys never leave your machine.

Algorithms

  • SHA-256 / SHA-512: Modern cryptographic standards for integrity and blockchain.
  • SHA-384 / SHA-1: NIST-standard secure hash algorithms.
  • MD5: 128-bit checksum algorithm popular for file verification and cache keys.
  • HMAC: Keyed-hash authentication to verify data integrity and authenticity.

Client-Side Security

All calculations run locally using hardware-accelerated WebCrypto primitives. Ideal for hashing sensitive tokens, verification checksums, passwords, and API signatures securely.
