Crypto & Hash

Hash Generator

Suggest an improvement

Generate cryptographic hashes of any text using the Web Crypto API. Useful for fingerprinting, integrity checks, and ETag generation. Computation runs locally — your input is never uploaded.

Browser-local execution

Inputs stay inside the current tab unless you copy, download or explicitly export.

Session handoff

Magic Paste can pass input to a target tool through sessionStorage, never through the URL.

User-owned state

Favorites, recent tools and workflow history are local browser data you can clear from the browser.

FAQ

Why is MD5 not included?
MD5 (and SHA-1 to a lesser extent) is cryptographically broken. The Web Crypto API only ships secure hashes. Use SHA-256 or stronger for any security-relevant work.
Are there file hashes?
Not yet — text only for this first version. File hashing is on the roadmap.
