Computes the hash with your browser's Web Crypto API. A hash is a one-way fingerprint: it can't be reversed. (SHA-1 is deprecated for security.)

This hash generator computes SHA-1, SHA-256, SHA-384 and SHA-512 digests of any text. Pick an algorithm, type your text, and the hexadecimal hash updates as you type.

One-way fingerprints

Hashes are used to verify file integrity, index data and store password fingerprints. They’re one-way: identical input always yields identical output, but the original text can’t be recovered. Everything runs in your browser via the Web Crypto API.

FAQ

What is a hash?

A hash is a fixed-length fingerprint of your input. The same text always produces the same hash, but you can't work backwards from the hash to the text.

Which SHA algorithm should I use?

Use SHA-256 for general purposes — it's fast and secure. SHA-384 and SHA-512 give longer digests. Avoid SHA-1 for anything security-related; it's broken for collision resistance.

Is my text sent to a server?

No. The hash is computed locally with your browser's Web Crypto API, so your text never leaves your device.
