Generate SHA hashes locally in your browser (SHA-1 / SHA-256 / SHA-384 / SHA-512). No upload.

Tip: Explanations come first. The tool is below. Ads are placed last.

Overview

Generate hashes locally for quick checks, fingerprints, and debugging. Hashes are one-way digests used to compare content, verify integrity, or create stable identifiers.
Enter text, choose a hash algorithm (via Web Crypto where available), and copy the output. Your input never leaves your device.

FAQ

Does this tool upload my data?
Most tools run locally in your browser. If a tool ever needs a network request (for example, to load a library), it will be mentioned on the page.

Why does the output look different from another site?
Different tools can use different defaults (timezones, whitespace rules, encoding behavior). Check the options and try a small sample first.
