Random Hash Generator - Hex & Alphanumeric
Generate a random hash-like string in hex or alphanumeric format at a chosen length, using crypto.getRandomValues for genuine randomness.

How the Random Hash Generator Works
This tool generates a random hex or alphanumeric string of your chosen length (16, 32, or 64 characters), using your browser's cryptographically secure random number source (crypto.getRandomValues) so the output is genuinely random and unpredictable, not just a pseudo-random sequence.
How to Use It
- Choose a character set — Hex (0-9 and a-f) or Alphanumeric (letters and numbers).
- Choose a length — 16, 32, or 64 characters.
- Click "Generate Random Hash" and copy the result.
Example
A 32-character hex result might look like "a13f9c2e8b0d47f6a91c5e3d2b7f8016" — a random string the same length and shape as many real hash outputs, but not derived from any input.
Common Use Cases
- Generating placeholder IDs or tokens for testing an app or API.
- Creating random-looking identifiers for mock data or sample database records.
- Filling in a field that expects a hash-shaped value during development or QA.
- Producing a random string for a temporary file name, cache key, or test fixture.
FAQs
Is this a real hash of something I typed?
No — this tool does not accept any input to hash. It generates a random-looking string of the length and character set you choose, for use as a test identifier or token, not a cryptographic hash (like SHA-256) of actual data. If you need to hash real input, use a dedicated hash generator tool instead.
How random is the output?
It uses your browser's crypto.getRandomValues API, a cryptographically secure random number source, rather than the weaker Math.random(), so the output is genuinely unpredictable.
Can two generated hashes be the same?
It is possible in theory, but extremely unlikely at 32 or 64 characters — the pool of possible combinations is astronomically large.
