Hash results

Choose text or a file, then generate its hashes.

SHA-256, SHA-384 and SHA-512 use Web Crypto. Hashes are one-way fingerprints, not encryption. Hashing empty text is supported.

Frequently Asked Questions

How does Hash Generator work?

The browser Web Crypto API computes SHA hashes. Hashes are one-way fingerprints and cannot be decoded.

Does this tool upload or save my input?

Core processing happens locally in this browser tab. Input and output are not sent to a processing server or stored automatically. Copy and download only occur when you request them.

What happens with large or invalid inputs?

Input limits and errors are shown in the workspace. JSON supports up to 1 MB and 100 nesting levels; large previews can be truncated while downloads retain the full result.
