A QUICK WALKTHROUGH

How to use it

  1. 01Choose a local file or paste the exact text.
  2. 02Generate integrity strings for all three algorithms.
  3. 03Use the hash with a trusted script or stylesheet release.

What this check can tell you

A hash identifies bytes, not their author or safety. Compare against a trusted source. Text is encoded as UTF-8; uploaded files are hashed as their exact bytes. Cross-origin SRI also requires CORS support.

The initial review processes files in this tab. If you choose the optional AI summary, the displayed findings are sent to Cloudflare AI; your raw file, result tables and decoded token claims are excluded.
