            How is this truly random?

            This tool generates cyrptographically secure random numbers using randomness from within your device.

            This is done in the browser using the web cryptography API. (If your browser doesn't support this, a warning message will display above the tool)

            If you have JavaScript turned off cryptographically secure random numbers will be generated on a server for you.
