Hash Inspector

Create SHA digests without leaving your browser.
Waiting for input.

Hash Inspector is a local browser utility for checksum notes, content fingerprints, deployment notes, and quick integrity checks.

What it does

  • Creates SHA-1, SHA-256, SHA-384, and SHA-512 digests.
  • Shows digest output in hexadecimal and base64.
  • Keeps copied text in the browser while the digest is created.
  • Gives a small repeatable surface for release notes and support documentation.

Use cases

  • Generate a quick SHA-256 digest for a copied value.
  • Record a content fingerprint in a deployment note.
  • Compare digest formats while documenting a release artifact.
  • Check a short integrity value without pasting data into a remote utility.

Local privacy boundary

The input is processed with the browser's Web Crypto API. The text you paste is not uploaded to graysond.xyz, sent to analytics, or stored by this site.

How to read the output

Use the same algorithm on both sides when comparing values. A digest only matches the exact input and algorithm used to create it.

Limits

Hash Inspector does not prove that a downloaded file came from a trusted source. It only creates a digest for the exact input you provide.

Use Passphrase Review for human secret checks, or Security for the site's local-tool boundary.
