About Hash Generator

A hash generator computes a fixed-length fingerprint of your text using a cryptographic hash function. Type or paste text and get its SHA-1, SHA-256, SHA-384, and SHA-512 digests instantly, computed with the browser's Web Crypto API. The same input always produces the same hash, and your text is never uploaded.

Frequently asked questions

Which hash algorithm should I use?
SHA-256 is the modern default for integrity and fingerprints. SHA-384/512 give longer digests. SHA-1 is legacy and broken for security — use it only for compatibility.
Can I reverse a hash back to the text?
No. Cryptographic hashes are one-way by design; you can't recover the input from the digest.
Why isn't MD5 here?
MD5 isn't part of the browser's Web Crypto API and is cryptographically broken, so it's intentionally omitted.
