Crypto & Hash

Hash Generator

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.

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.
