The shell script can be used on Linux and macOS to distribute true random bytes downloaded from an AlphaRNG device using a named pipe.

This is the simplest way to access true random bytes concurrently from a range of applications running in Linux user spaces.

It can be accomplished with the following steps:

Make sure the software kit is built with make and installed successfully.

Verify that an AlphaRNG device is plugged into an available USB port.

Open a command line window and enter the following command:


If successfully, the script will create a named pipe /tmp/alpharng and will make it available for read access.

In a new command line session verify the random bytes are available with the following command:

dd if=/tmp/alpharng of=/dev/null iflag=fullblock bs=12000000 count=1

You can now access random bytes by reading from /tmp/alpharng like a regular binary file.

To schedule the pipe server script to run as a background process at boot time then follow these steps:

Edit the crontab configuration with the following command:

sudo crontab -e

Add the following line to the existing crontab configuration:

@reboot /usr/local/bin/ >> /var/log/run-alrng-pserver.log 2>&1
