About this tool
SHA-256 turns any text into a fixed 64-character hexadecimal fingerprint: the same input always gives the same hash, while even a tiny change gives a completely different one. This tool computes the hash with the browser's WebCrypto API, so the text never leaves your device. A hash is one-way, so it cannot be reversed back into the original text.
Frequently asked questions
Can I get my original text back from a hash?
No. SHA-256 is one-way by design; the only way to check a text is to hash it again and compare the two hashes.
Does changing one letter change the hash a lot?
Yes. That avalanche effect is deliberate: even a single-character change produces a hash that looks unrelated to the original.
