Password & Hash Tools

Hash Generator

Free hash generator for SHA-256, SHA-512, MD5, HMAC, and more. Pick an algorithm in Mode, hash text locally, and copy digests for tests.

One hash page covers the digests developers reach for in fixtures and integrity checks. Choose SHA-256, SHA-512, MD5, HMAC, or bcrypt-style output in Mode and hash text in your browser.

About Hash Generator

Checksums confirm a string did not change between systems. SHA-256 remains a common default; older MD5 and SHA-1 still appear in legacy fixtures and file manifests.

HMAC mode adds a secret key for keyed message authentication samples. Bcrypt-style output helps when a form or docs need a placeholder password hash shape.

Prefer purpose-built libraries in production. This hub is for quick digests while building tests and docs—not for storing real user passwords.

How to Use Hash Generator

  1. Paste the text to hash.
  2. Select the algorithm under Mode (use HMAC secret when required).
  3. Run the generator.
  4. Copy the digest into your fixture or ticket.

For password storage in real apps, use your framework’s password hasher—not a quick online digest demo.

Common Use Cases

Fixture digests

Create stable SHA-256 values for golden-file tests.

Legacy MD5

Reproduce older checksum formats when migrating data.

HMAC samples

Generate keyed hashes for webhook signature examples.

Tips and best practices

Hashing sits with password and secret generators for end-to-end test data prep.

Frequently Asked Questions

Quick answers about how this tool works and when to use it.

Which algorithm should I pick?

Prefer SHA-256 or SHA-512 for new work. Use MD5/SHA-1 only when matching a legacy system.

Is HMAC the same as SHA-256?

HMAC combines a hash with a secret key. Plain SHA-256 does not require a key.

Is bcrypt here production-grade?

Treat bcrypt-style output as a sample for UI and docs. Real auth stacks should hash passwords with vetted libraries and salts.

Do you keep my input?

Hashing runs in the browser for normal paste use.

Can I hash files?

This page hashes text you paste. Large binary files belong in a dedicated file-hash utility or CLI.
