How it works

  • Encodes text as UTF-8.
  • Hashes with crypto.subtle.digest.
  • Returns lowercase hexadecimal.

Common use cases

  • Check file manifests.
  • Create test hashes.
  • Verify deterministic strings.

Code example

crypto.subtle.digest('SHA-256', new TextEncoder().encode(input))

Hashing is one-way

SHA-256 creates a deterministic digest from input text. It is not encryption and cannot be reversed to recover the original input.

Password caution

Do not use raw SHA-256 as a password storage strategy. Password storage requires salts and slow password hashing algorithms.

FAQ

Is my input uploaded?

No. This MVP runs tool logic in your browser and does not send tool input to a server.

Can I use this on mobile?

Yes. Pages are mobile-first and designed for quick copy, paste, and share workflows.

Does the tool store history?

No. The MVP does not store tool input history or create user accounts.

Should I verify important output?

Yes. These tools are designed for productivity, but production changes and financial decisions should be independently verified.

Can the tool run after the page loads?

Yes. The interactive logic runs in the browser once the static page and JavaScript island are loaded.

What input format should I use?

Use the examples on the page as a starting point, then replace them with your own local input.
