Questions

Good to know

Is my text sent anywhere?

No. Everything happens in your browser on your own device. Nothing you type is sent to a server or saved.

Which hash should I use?

SHA-256 for most uses. MD5 and SHA-1 are only for checking files: they are no longer safe for passwords or security.

Is my file uploaded?

No. The file is read and hashed inside your browser.
