SRI Hash Generator

Generate SHA-256, SHA-384, and SHA-512 Subresource Integrity values in the browser for text or files, and build ready-to-use integrity HTML snippets.

SRI Hash Generator

The SRI Hash Generator creates SHA-256, SHA-384, and SHA-512 Subresource Integrity values for text or files locally in the browser and can also build reusable integrity HTML snippets.

How do you use it?

  1. Choose text mode or file mode.
  2. Enter the resource contents or upload the static asset file.
  3. Generate the hashes and copy the SRI value you need.
  4. If you have a resource URL, copy the generated HTML integrity snippet directly.

Features

  • Supports text and file input
  • Outputs SHA-256, SHA-384, and SHA-512 SRI values together
  • Builds HTML snippets with integrity and crossorigin

Why use this tool?

  • Useful for CDN scripts, stylesheets, and frontend asset integrity checks
  • Faster than manually converting hashes from command-line tooling and easier to paste into templates
  • Handy for verifying third-party or self-hosted asset integrity before release
