Compute SHA-1, SHA-256, SHA-384 and SHA-512 digests of any text using the browser Web Crypto API. The text never leaves your device and no data is uploaded. 100% Local
How to Use the Hash Generator
Type or paste your text, choose an algorithm (or all of them) and press Compute. The hexadecimal digest of each selected algorithm is shown below.
About hashing
Hashing is one-way: the original text cannot be recovered from a digest.
SHA-1 is shown for compatibility only; prefer SHA-256 or stronger for security.
Hashes are computed in your browser with the Web Crypto API.

All processing runs locally in your browser. Your text is not uploaded to any server.
A hash is not a password store — never treat a plain digest as protection for secrets.
