Formula used
Uses the browser's built-in Web Crypto API to compute a SHA-256 hash — a one-way cryptographic fingerprint of the input text.
Example: "hello" hashes to 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824.

FAQ
Frequently asked questions
What is a hash?
A fixed-length fingerprint of input data — the same input always produces the same hash, but you can't reverse a hash back to the original text.
Is my text sent to a server?
No — the hash is computed entirely in your browser using the Web Crypto API.
What is SHA-256 used for?
Verifying file integrity, password storage (with additional salting), and blockchain applications.
Does a tiny change in input change the hash a lot?
Yes — even a single character difference produces a completely different hash.
