Calculate MD5, SHA-1 in your browser using HTML5 and WebWorkers

In plain words

This tool lets users compute MD5 and SHA-1 hashes directly in their web browser using HTML5 and WebWorkers technology. It's designed for anyone who needs to generate or verify file hashes without installing additional software. The application processes hashing locally in the browser, which means data stays on the user's machine rather than being sent to a server.
