Hashes are everywhere in the digital world: checksums for file downloads, version control systems, fingerprints, password databases and verification, message authentication, digital signatures, blockchains etc.

As a developer, I often find myself in the situation where I quickly need to verify a hash, or generate a hash for some reason or other. That’s why I built the flrx39 hash tool: it lets you quickly evaluate some popular hashes in the browser. None of the data you input is sent to servers, all of it remains in your browser! It’s your data, after all. Check it out.
