Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text or files. Compare hashes, generate HMACs, and verify checksums.

How to use it

  1. Type or paste text, or switch to File and drop a file — every hash is computed in your browser.
  2. Pick an algorithm to put its digest first, and choose hex, upper-case hex or Base64 output.
  3. Copy one digest or all of them, or use HMAC, Compare and Verify to sign messages and check downloads.

What is a Hash Generator?

A hash generator computes cryptographic hash values from text or files. A hash function takes input of any size and produces a fixed-size output (digest) that uniquely represents the input. This tool supports MD5, SHA-1, SHA-256, SHA-384, SHA-512, and HMAC variants using the Web Crypto API for secure client-side computation.

Common use cases

  • Generating checksums to verify file integrity
  • Creating password hashes for security testing
  • Computing HMAC signatures for API authentication
  • Verifying downloaded files against published hashes
  • Hashing sensitive data for comparison without exposing originals

Frequently asked questions

What is the difference between MD5 and SHA-256?

MD5 produces a 128-bit hash and is fast but cryptographically broken — collisions can be generated easily. SHA-256 produces a 256-bit hash and is currently considered secure. Use SHA-256 or SHA-512 for any security-sensitive application.

What is HMAC?

HMAC (Hash-based Message Authentication Code) combines a hash function with a secret key to verify both data integrity and authenticity. Unlike a plain hash, HMAC proves the message was created by someone who knows the secret key.
